Provides a low large diameter head, butwith characteristically high outer edge alongthe-outer periphery of the head where drivingaction is most effective for high tightening'torques. Slightly different head contour wheresupplied with recessed head.FLAT HEAD: Supplied to standarddimensions with an 80' to 82' angle to be usedwhere finished surfaces require a flush fasteningunit. The countersunk portion offers goodcentering possibilities.ROUND HEAD: Not recommended for newdesign (see pan head). This head was the mostuniversally used design in the past.OVAL HEAD: Fully specified as "ovalcountersunk", this head is identical to thestandard flat head. but possesses. in addition, arounded, neat appearing upper surface forattractiveness of design.FILLISTER HEAD: The-standard oval fillister head has a smaller diameter than the round head. but is higher with a correspondingly deeper slot. The smaller diameter head increases the pressure applied on the smaller area and can be assembled close to flanges and raised surfaces. Headed in counter bored dies to Insure concentricity, they may be used successfully in counter bored holes. BINDING HEAD (Straight Side): Most generally used in electrical and radio work because of its identifying undercut beneath the head, which binds and eliminates fraying of stranded wire. Offers an attractively designed, medium-low head with ordinarily sufficient bearing surface. 'Not ordinarily recommended as a Phillips Recessed head-see Pan Head for better functional design.TRUSS HEAD: Also known as oven head, stove head, and oval binding head. A low, neat appearing, large diameter head having excellent design qualities, and as illustrated can be used to cover larger diameter clearance holes in sheet metal when additional play In assembly tolerance is required. Suggest pan head as a substitute.HOLT HEAD (PATENTED): Provides the perfect tamper-proof assembly. Theft-proof-decorative, yet inexpensive. Special drivers available for field removal or power driven assembly machines.ONE-WAY HEAD: This ingenious, tamper-proof type of head, once assembled cannot be removed. yet is driven with a standard screw driver. Manufactured with amazing economy in productive quantities, this, simple design can frequently solve costly assembly problem.PHILIPS FINISHING WASHER HEAD: Designed as a neat appearance product for the electronic and appliance trade with all threaded styles.WASHER HEAD: This design has the finished appearance of a conventional round head plus washer and was originality created to provide extra large bearing surface under the head. The modern "truss" head (carried in stock) normally answers this purpose. When a. larger diameter is required this washer head is recommended.FLAT AND OVAL HEADS (UNDERCUTI: This Is the standard flat or oval head SO' to 82' countersunk screw which has the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths. As Illustrated, it will fit a standard counterbored hole and Is particularly adaptable to flush assemblies in thin stock.FLAT HEAD (100' COUNTERSUNK): This special flat head screw has been developed for applications requiring flush surfaces, and is recommended for use In soft materials. to distribute pressure over a larger and less angular surface.

Provides a low large diameter head, butwith characteristically high outer edge alongthe-outer periphery of the head where drivingaction is most effective for high tightening'torques. Slightly different head contour wheresupplied with recessed head.FLAT HEAD: Supplied to standarddimensions with an 80' to 82' angle to be usedwhere finished surfaces require a flush fasteningunit. The countersunk portion offers goodcentering possibilities.ROUND HEAD: Not recommended for newdesign (see pan head). This head was the mostuniversally used design in the past.OVAL HEAD: Fully specified as "ovalcountersunk", this head is identical to thestandard flat head. but possesses. in addition, arounded, neat appearing upper surface forattractiveness of design.FILLISTER HEAD: The-standard oval fillister head has a smaller diameter than the round head. but is higher with a correspondingly deeper slot. The smaller diameter head increases the pressure applied on the smaller area and can be assembled close to flanges and raised surfaces. Headed in counter bored dies to Insure concentricity, they may be used successfully in counter bored holes. BINDING HEAD (Straight Side): Most generally used in electrical and radio work because of its identifying undercut beneath the head, which binds and eliminates fraying of stranded wire. Offers an attractively designed, medium-low head with ordinarily sufficient bearing surface. 'Not ordinarily recommended as a Phillips Recessed head-see Pan Head for better functional design.TRUSS HEAD: Also known as oven head, stove head, and oval binding head. A low, neat appearing, large diameter head having excellent design qualities, and as illustrated can be used to cover larger diameter clearance holes in sheet metal when additional play In assembly tolerance is required. Suggest pan head as a substitute.HOLT HEAD (PATENTED): Provides the perfect tamper-proof assembly. Theft-proof-decorative, yet inexpensive. Special drivers available for field removal or power driven assembly machines.ONE-WAY HEAD: This ingenious, tamper-proof type of head, once assembled cannot be removed. yet is driven with a standard screw driver. Manufactured with amazing economy in productive quantities, this, simple design can frequently solve costly assembly problem.PHILIPS FINISHING WASHER HEAD: Designed as a neat appearance product for the electronic and appliance trade with all threaded styles.WASHER HEAD: This design has the finished appearance of a conventional round head plus washer and was originality created to provide extra large bearing surface under the head. The modern "truss" head (carried in stock) normally answers this purpose. When a. larger diameter is required this washer head is recommended.FLAT AND OVAL HEADS (UNDERCUTI: This Is the standard flat or oval head SO' to 82' countersunk screw which has the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths.
