TAPTITEII三角自攻螺丝标准DUO-TAPTITE CORFLEX ?DUO-TAPTITEReduced In-Place Cost!!TAPTITE II ? and DUO-TAPTITE ? thread rolling screws reduce in-place fastener costs and provide vibration resistant assemblies. TAPTITE II ? and DUO-TAPTITE ? thread rolling screws are used to create strong, uniform load carrying internal threads into untapped nut members upon installation. When REMINC developed the original TAPTITE ? TRILOBULAR? shape thread rolling screw, it revolutionized the use of threaded fasteners in high production assembly. Assembly efficiency and joint performance along with lower in-place fasten-ing cost, havebeen the benefits of using TAPTITE ? screws. TAPTITE II ? and DUO-TAPTITE ? screws and bolts continue these benefits along with meeting the quality and performance needs of the future.Lower In-Place Fastening CostsOnly 15% of the total in-place cost of a fastening is the cost of the screw or bolt. TAPTITE II ? and DUO-TAPTITE ? screws and bolts lower the cost of the remaining 85%.The following is a list of some of the cost-savings advantages of using TAPTITE II ? and DUO-TAPTITE ? thread rolling screws.-Elimination of separate tapping operations and associated costs. -Built-in resistance to vibrational loosening eliminates the need for lock washers, adhesives, or plastic patches and plugs. - Generates stronger mating threads with uninterrupted grain flow due to work hardening of the nut for higher stripping resistance. -Accepts larger pilot hole variations than drilled and tapped holes. -Works in punched, drilled, cored and extruded holes in many different metals. -With use of CORFLEX ? metallurgy, can be provided in grade strengths of high tensile bolts for use in struc-tural applications in deep thread lengths of engagement. -No assembly line cross threading. -Prevailing torque often equals or exceeds locking screw standards. - Manufactured to REMINC standards all over the world by over 68 of the world’s leading fastener, fastenerprocessing and tooling companies.Originators of the TRILOBULAR?

COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Why TAPTITE II ? Over TAPTITE ?Screws? TAPTITE II ? screws bring benefits to both fastener manufacturer and end user. TAPTITE II ? screws were designed to: - Provide a more efficient manufacturing method and tool design to result in a more consistent product.- Be applicable to the quality and SPCphilosophies of today’s market by utilizing the capabilities of today’s state of the art tooling and fastener manufacturing equipment. - Provide more consistent torque performance, lowerthread forming torque and lower end load necessary to initiate thread forming, thanany other thread forming or thread rollingscrew including the original TAPTITE ? screw.Behind the scenes, REMINC has provided its licensed manufacturers with a total quality system for manu-facturing TAPTITE II ? fasteners. Included are design and processing failure mode and effects analysis pro-cedures, statistical in process control data collectionsystem, and improved inspection procedures and cri-teria. Although all REMINC products are designed for consistent manufacture and performance, TAPTITE II ? fasteners were physically re-designed tomeet the above quality system, to be the quality flag-ship of TRILOBULAR? products.Note: TAPTITE II ? is often designated TYPE TT AND TT-II“The Controllable Product ?”COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Better starting stability – Axial AlignmentLess misalignment at start of driving operation . . . the self-aligning characteristic of DUO-TAPTITE ? screws reduces operator fatigue; eliminates interruptions in produc-tion; adds speed to every fastening opera-tion. Suitable for automated and robotic assembly. B – Higher prevailing torque Superior elastic action of a DUO-TAPTITE ? screw gives it better lock-ing characteristics than many fasteners specifically designed aslocking screws!

End pressure wasmanually developed, measured and recorded by anelectronic load cell and recorder. Drive, prevailingand strip torque values, and torque-tension valueswere measured with a GSE torque cell and re-corded on a BLH electronic recorder. All test datais based on 5/16 - 18 or M8 x 1.25 screws.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Suggested hole sizes for TAPTITE II ? & DUO-TAPTITEScrews and Bolts at various percentages of thread engagementEXAMPLE - The shaded areaindicates that an M5 - 0.8 screw size in a 4.58 hole size provides 80% threadengagement.Because the above values are based on a linear relation between hole size and percentage thread engagement, the hole data becomes less accurate for engagements less than 70%.Note also, these hole sizes are based on the U.S. basic thread depth of .6495 times the pitch and are calculated using nominal screw diameters.Hole = D - (0.6495 x P x %), where D = nominal screw diameter.(1) Pilot holes listed under 90% & 85% (Thread Percent) also recommended for single punch extruded holes.See Page 11For Pilot Hole Tolerance in terms of thread percentage, we suggest +5% to -10% of the nominal value, percent thread value.EXAMPLE: If 80% is the percent thread for the nominal hole, the minimum hole would yield 85% thread and themaximum hole would yield 70% thread.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Recommended pilot hole sizes forTAPTITE II ? & DUO-TAPTITE ?Screws and Bolts for steel nut member thicknesses (Expressed in terms of screw diameters)APPLICATION DUTY CLASS - A general term used here to group material thickness in terms of screw diameters. For example, the average material thicknesslisted under "medium-heavy" equals 75% of the screw diameter.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.NOTES: - Torque values for metric sizes in New-ton-meters - Torque values for inch sizes in pound-inches - Plate dimensions for metric sizes in mil-limeters and for inch sizes in inches - Torque values were developed using hex washer head screws,zinc plated plus lubricity wax, driven at low speed underlaboratory-controlled conditions. - Values shown represent the above con-ditions only and should not be used in lieu of proper application testing. The data is presented to provide the user with an estimate of what could be achieved in an actual application having a thicker or thinner nut member harder or softer material, different hole or fas-tener all contribute to variations in torque performance. - Recommended tightening torque is in-tended to induce approximately 30,000 to 50,000 psi clamping force. - Prevailing first removal torque, the torque necessary to remove the screw after the head has been un-seated, is an indication of TAPTITE II ? screws inherent resistance of free turning which is an indication of resistance to loosen-ing under vibration, even without screw head being seated. * Indicates probability that nut threads will strip. ? Indicates probability that screw will break.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.The above hole sizes are suggested starting points to be confirmed by actual testing. Extrusion Dimensions can vary due to tooling design and material being extruded.Approximate Material Thickness "T"Suggested extruded holes in light-gauge steel for TAPTITE II ? and DUO-TAPTITE ?Screws & Bolts (Continued from page 11)COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Lengths greater than 25mm ± 1.3mmCOPYRIGHT 2001, Research Engineering & Manufacturing Inc.Self-aligning point feature‘finds’ the holes, lines them upand fastens them in oneoperation.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.TEST PARAMETERS -Test material: cold-rolled draw qualityaluminum killed steel platehardened to Rb 50-55Test washer: .063 thick steelClearance hole: .180(#6), .200(#8), .220(#10),.280(1/4”)Drive speed: 250 RPM under loadDriver end load: 8lbs.- These values may vary proportionately to application.Smaller hole sizes for example, will increase drive, first off,strip torques, etc. Material thickness will also effect torque/ tension values as indicated in the table. These values were derived from averages of over 1800 laboratory tests under specific conditions. These values are to be used only as aguide since actual application performance results may vary.Reusable - Subjecting the POWERLOK? screw to increasingclamp load results in continuously in-creasing thread flankcontact so that unit pressure between mating surfaces tends to remain constant, an important factor in diminishing galling and abra-sion. Together with the burnishing action of the TRILOBULAR? crests means continued locking ef-fectiveness, after repeated insertions and removals. Locking performance - Will meet or exceed IFI 124 (inch) or IFI 524 (metric) Specifications for Pre-vailing Torque Locking Screws. Transverse vibration test data available upon request. Actual perform-ance will vary depending on effective finish lubricity and nut condition.No special taps - You save time and money by using a regular nut or Class 2B (6G) tapped hole. POWERLOK? is precision made - so the hole thread doesn’t have to be. Applications - Widely used in automotive and other mass-assembly operations. You can use POWERLOK?screws wherever you need reliable vibration resistance, continued high performance, despite repeated assem-bly/disassembly using normal tapped holes. They can be used in pre-tapped holes in ductile metals. STANDARD MATERIAL - Depending on part size, low carbon, medium carbon or alloy steel is selected. Then the steel is hardened and tempered to the optimum combination of tensile strength and toughness. Ten-sile or torsional strength can be more than twice that of machine screws. Screws can be made in strength levels to suit a wide range of application requirements. Property Class 10.9 is often preferred. Finishes can be supplied as required.The PLASTITE ? family of TRILOBULAR? screws for fastening in plastic The following is intended as a guide tochoosing threaded fasteners which will provide optimum application and per-formance characteristics in a wide range of plastics. It contains detailed information on PLASTITE ? thread- rolling screws. Because of the variations in the manu-facture of individual grades of plastics,particularly in the quantity of filler used, it is imperative that tests be conducted on each proposed application by a com-petent engineering laboratory.

三角自攻螺丝标准
三角自攻螺丝是一种具有特殊形状的螺纹成型螺丝，主要用于提高螺丝锁付作业的可靠性和降低成本。
它的螺纹为三角形，底孔攻牙时以三角形顶点进行塑性加工，可一面攻牙，一面完成锁付作业。
三角自攻螺丝的标准涉及多个方面。
首先，其螺纹型号分为TA、TB、TC、TD、TE、TF、TG、TH、TJ、TK、TL、TM、TN、TP、TQ、TR等16种，其中TA、TB、TC、TD为常规型号。
这些不同型号的螺丝具有不同的牙距和长度，一般而言，螺丝的牙距为0.9mm或1.0mm，而长度则在6mm-100mm之间。
在材质方面，三角自攻螺丝包括碳钢、不锈钢、合金钢等多种材质。
不同的使用环境和要求需要选择合适的材质。
例如，在户外或潮湿的环境中，不锈钢螺丝可能是更好的选择，而在一些高温或腐蚀性的环境中，合金钢螺丝则更适合。
此外，三角自攻螺丝的设计标准也十分重要。
其标称直径、螺距或牙数、圆形直径、三角形直径、底孔径、标称长度、破坏扭力、抗张力、表面硬度、心部硬度以及渗碳硬化层深度等都是需要考虑的因素。
这些因素决定了螺丝的性能和使用寿命。
与公制机械牙螺丝相比，三角自攻螺丝具有底孔不需预先攻牙、防松力强、不需使用防松垫圈、强度好可用较小直径螺丝等优点。
而与一般自攻螺丝相比，三角自攻螺丝具有锁进扭力小、锁付钮力大、保持力大、防松效果好、无切屑粉锁付发热量小等优点。
总的来说，三角自攻螺丝是一种高效且可靠的螺丝锁付方式，能够降低成本并提高作业效率。

TAPTITE II 三角自攻螺丝标准
DUO-TAPTITE CORFLEX ®DUO-TAPTITEReduced In-Place Cost!!TAPTITE II ® and DUO-TAPTITE ® thread rolling screws reduce in-place fastener costs and provide vibration resistant assemblies. TAPTITE II ® and DUO-TAPTITE ® thread rolling screws are used to create strong, uniform load carrying internal threads into untapped nut members upon installation. When REMINC developed the original TAPTITE ® TRILOBULAR™ shape thread rolling screw, it revolutionized the use of threaded fasteners in high production assembly. Assembly efficiency and joint performance along with lower in-place fasten-ing cost, have been the benefits of using TAPTITE ® screws. TAPTITE II ® and DUO-TAPTITE ® screws and bolts continue these benefits along with meeting the quality and performance needs of the future.Lower In-Place Fastening CostsOnly 15% of the total in-place cost of a fastening is the cost of the screw or bolt. TAPTITE II ® and DUO-TAPTITE ® screws and bolts lower the cost of the remaining 85%.The following is a list of some of the cost-savings advantages of using TAPTITE II ® and DUO-TAPTITE ® thread rolling screws.-Elimination of separate tapping operations and associated costs. -Built-in resistance to vibrational loosening eliminates the need for lock washers, adhesives, or plastic patches and plugs. -Generates stronger mating threads with uninterrupted grain flow due to work hardening of the nut for higher stripping resistance. -Accepts larger pilot hole variations than drilled and tapped holes. -Works in punched, drilled, cored and extruded holes in many different metals. -With use of CORFLEX ® metallurgy, can be provided in grade strengths of high tensile bolts for use in struc-tural applications in deep thread lengths of engagement. -No assembly line cross threading. -Prevailing torque often equals or exceeds locking screw standards. - Manufactured to REMINC standards all over the world by over 68 of the world’s leading fastener, fastenerprocessing and tooling companies.Originators of the TRILOBULAR™ Family of Fasteners Providing Technical Support, Marketing Support and Innovative Fastener DesignCOPYRIGHT 2001, Research Engineering & Manufacturing Inc.level bolts are required. COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Why TAPTITE II ® Over TAPTITE ®Screws? TAPTITE II ® screws bring benefits to both fastener manufacturer and end user. TAPTITE II ® screws were designed to:- Provide a more efficient manufacturing method and tool design to result in a more consistent product.- Be applicable to the quality and SPCphilosophies of today’s market by utilizing the capabilities of today’s state of the art tooling and fastener manufacturing equipment. - Provide more consistent torque performance, lower thread forming torque and lower end load necessary to initiate thread forming, thanany other thread forming or thread rollingscrew including the original TAPTITE ® screw.Behind the scenes, REMINC has provided its licensed manufacturers with a total quality system for manu-facturing TAPTITE II ® fasteners. Included are design and processing failure mode and effects analysis pro-cedures, statistical in process control data collectionsystem, and improved inspection procedures and cri-teria. Although all REMINC products are designed for consistent manufacture and performance, TAPTITE II ® fasteners were physically re-designed tomeet the above quality system, to be the quality flag-ship of TRILOBULAR™ products.Note: TAPTITE II ® is often designated TYPE TT AND TT-II“The Controllable Product ®”COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Better starting stability – Axial AlignmentLess misalignment at start of driving operation . . . the self-aligning characteristic of DUO-TAPTITE ® screws reduces operator fatigue; eliminates interruptions in produc-tion; adds speed to every fastening opera-tion. Suitable for automated and robotic assembly. B – Higher prevailing torque Superior elastic action of a DUO-TAPTITE ® screw gives it better lock-ing characteristics than many fasteners specifically designed aslocking screws! Competitive round-bodied, thread-forming fasteners have nolocking torque. Graph shows comparison of DUO-TAPTITE ® screw with IFI-124 minimum requirement for self-locking screws.TYPICAL ANGULARITY** Starting angle of four specimens of each type measured at 20x full size on an optical comparator.Lower starting end pressureLower starting end pressure combines with lower driving torque to reduce time and power costs right down the line. A – Higher strip-to-drive ratio The higher, more uniform, strip-to-drive torque ratio of DUO-TAPTITE® screws pro-vides a built-in safety factor against over-driving. Eliminates broken screws, dam-aged mating threads and inferior fastenings.Torque-tension comparison M8 x 1.25 DUO-TAPTITE ® vs.TAPTITE ® FastenerSuperior tension at any given applied torque (with normal clamping pressure) is a major factor in the better holding capa-bility of a DUO-TAPTITE ® screw.NOTE: All screws were tested in unthreaded weld nuts of uniform hardness (Rockwell B 82-84) hav-ing 7.1mm hole diameters. End pressure wasmanually developed, measured and recorded by anelectronic load cell and recorder. Drive, prevailingand strip torque values, and torque-tension valueswere measured with a GSE torque cell and re-corded on a BLH electronic recorder. All test datais based on 5/16 - 18 or M8 x 1.25 screws.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Suggested hole sizes for TAPTITE II ® & DUO-TAPTITE®Screws and Bolts at various percentages of thread engagementEXAMPLE - The shaded areaindicates that an M5 - 0.8 screw size in a 4.58 hole size provides 80% threadengagement.Because the above values are based on a linear relation between hole size and percentage thread engagement, the hole data becomes less accurate for engagements less than 70%.Note also, these hole sizes are based on the U.S. basic thread depth of .6495 times the pitch and are calculated usingnominal screw diameters.Hole = D - (0.6495 x P x %), where D = nominal screw diameter.(1) Pilot holes listed under 90% & 85% (Thread Percent) also recommended for single punch extruded holes.See Page 11For Pilot Hole Tolerance in terms of thread percentage, we suggest +5% to -10% of the nominal value, percent threadvalue.EXAMPLE: If 80% is the percent thread for the nominal hole, the minimum hole would yield 85% thread and themaximum hole would yield 70% thread.COPYRIGHT 2001, Research Engineering & Manufacturing Inc.Recommended pilot hole sizes forTAPTITE II ® & DUO-TAPTITE ®Screws and Bolts for steel nut member thicknesses (Expressed in terms of screw diameters)APPLICATION DUTY CLASS - A general term used here to group material thickness in terms of screw diameters.

These values werederived from averages of over 1800 laboratory tests underspecific conditions. These values are to be used only as aguide since actual application performance results may vary.Exceed IFI locking screw standards Have locking action you can’t wear out!Reusable - Subjecting the POWERLOK® screw to increasing clamp load results in continuously in-creasing thread flank contact so that unit pressure between mating surfaces tends to remain constant, an important factor in diminishing galling and abra-sion. Together with the burnishing action of the TRILOBULAR™ crests means continued locking ef-fectiveness, after repeated insertions and removals. Locking performance - Will meet or exceed IFI 124 (inch) or IFI 524 (metric) Specifications for Pre-vailing Torque Locking Screws. Transverse vibration test data available upon request. Actual perform-ance will vary depending on effective finish lubricity and nut condition.No special taps - You save time and money by using a regular nut or Class 2B (6G) tapped hole. POWERLOK® is precision made - so the hole thread doesn’t have to be. Applications - Widely used in automotive and other mass-assembly operations. You can use POWERLOK®screws wherever you need reliable vibration resistance, continued high performance, despite repeated assem-bly/disassembly using normal tapped holes. They can be used in pre-tapped holes in ductile metals. STANDARD MATERIAL - Depending on part size, low carbon, medium carbon or alloy steel is selected. Then the steel is hardened and tempered to the optimum combination of tensile strength and toughness. Ten-sile or torsional strength can be more than twice that of machine screws. Screws can be made in strength levels to suit a wide range of application requirements. Property Class 10.9 is often preferred. Finishes can be supplied as required.The PLASTITE ® family of TRILOBULAR™ screws for fastening in plasticThe following is intended as a guide to choosing threaded fasteners which will provide optimum application and per-formance characteristics in a wide range of plastics. It contains detailed information on PLASTITE ® thread-rolling screws.Because of the variations in the manu-facture of individual grades of plastics, particularly in the quantity of filler used, it is imperative that tests be conducted on each proposed application by a com-petent engineering laboratory.REMINC/CONTI’s network of licensees provide this testing service usually wit out obligation.

The past limitation in exploiting the in-place c o s t s a v i n g s o f l a r g e s i z e TRILOBULAR™ products was that the required screw hardness was achieved through case hardening. Case harden-ing is detrimental to structural appli-cations as the fastener would be sus-ceptible to differing modes of “brittle” failure. Tougher! That’s the whole reason why CORFLEX ® fasteners were invented! Screws come in many different strengths; ordinary machine screws are manufactured from non-hardened, low-carbon steel. Regular tapping screws are manufac-tured from low-carbon steel case hardened to 107 ksi minimum strength. Metric Grade 9.8 or inch Grade 5 ma-chine screws are manufactured to 930 MPA and 120 ksi minimum respec-tively. They are manufactured from low to medium carbon alloy or boron intensified steel. Metric Grade 10.9 or inch Grade 8 ma-chine screws are manufactured from medium carbon alloy steel to 1040 MPA and 150 ksi strength respec-tively.But until CORFLEX ®-I technology, there was no thread-forming orthread-rolling fastener with both the thread forming hardness of a tapping screw and the toughness of a grade strength machine screw!CORFLEX ®-I, TAPTITE II ®, TAPTITE ® CA and DUO-TAPTITE ® and screws and bolts are unique: They are manu-factured from 4037 alloy steel and custom heat treated throughout towhatever strength is required! Thiscould be Grade 8.8, 9.8, 10.9, 12.9 or anything in between! CORFLEX ®-I screws are neutral hard-ened so the bolt or screw has uniformstructure similar to grade strength machine screws. Then, after bolt strength is heat treated to the re-quired properties of applications, the thread rolling zone is induction hard-ened for thread forming capability.This selective zone heat treating isdone on customized automatic feed induction hardening machines. It is this two stage heat treatment that makes the CORFLEX ®-I version TAPTITE II ®, TAPTITE ® CA and DUO-TAPTITE ® screws unique; strong and tough in the load bearing areas but very hard in the thread rolling area. The combination of strength and t o u g h n e s s e n a b l e s , t h e CORFLEX ®-I screw to bend without breaking and withstand alternating or cyclical loads. Tension can be applied and relaxed almost indefinitely with-out encouraging fatigue cracking. C O R F L E X ®-N v e r s i o n s o f TAPTITE II ®, TAPTITE ® CA and DUO-TAPTITE ® screws are neutral hardened and tempered to desired strength or grade level. A subsequent zone hardening of the thread rollingpoint is not necessary as the intended use of CORFLEX ®-N screws and bolts is in soft ductile non-ferrous materials, such as zinc and aluminum. Addition-ally, POWERLOK ® screws are heat treated to CORFLEX ®-N Metallurgy. Above is an illustration of the excellent thread forming capability of a CORFLEX ®-I TAPTITE II ® bolt in producing deep threads of one diameter length or greater in heavy (multiple punch) extrusions as required for structural applications.
