螺纹与孔径对照表
螺纹与孔径对照表
螺纹（Thread）和孔径（Aperture）是两个不同的概念，在不同的领域有着不同的定义和用途。
以下是一些常见的螺纹与孔径对照表，但请注意具体的对应关系可能因应用场景和标准的不同而有所差异。
1. 螺纹与内孔：
- M2.5：2.5mm 孔径
- M3：3.0mm 孔径
- M4：4.0mm 孔径
- M5：5.0mm 孔径
- M6：6.0mm 孔径
- M8：8.0mm 孔径
- M10：10.0mm 孔径
- M12：12.0mm 孔径
- M14：14.0mm 孔径
- M16：16.0mm 孔径
- M20：20.0mm 孔径
2. 螺纹与外径：
- 1/4-20：1/4 英寸外径，20 TPI（每英寸的螺纹数）
- 3/8-16：3/8 英寸外径，16 TPI
- 1/2-13：1/2 英寸外径，13 TPI
- 5/8-11：5/8 英寸外径，11 TPI
- 3/4-10：3/4 英寸外径，10 TPI
- 1-8：1 英寸外径，8 TPI
- 1 1/4-7：1 1/4 英寸外径，7 TPI
- 1 1/2-6：1 1/2 英寸外径，6 TPI
- 2-4 1/2：2 英寸外径，4 1/2 TPI
- 2 1/2-4：2 1/2 英寸外径，4 TPI
- 3-3 1/2：3 英寸外径，3 1/2 TPI
这只是一个示例表格，实际应用中具体的对照关系可能会有所不同。
