螺丝攻牙径对照表.xls

螺螺丝丝攻攻牙牙钻钻孔孔径径和和滚滚造造径径对对照照表表 本表所推选之钻头孔径，是针对攻牙加工时，能够很容易的了解钻孔直径；而依据市售之标准钻头所选定的。在使用钻头的情况下，由于钻头的形状及尺寸、精度、被钻孔之材质等，对于所钻孔 的尺寸、精度有很大的影响，所以使用本表之钻孔径，若有不当之处，应视实际状况适当的变更钻头直径。本表是依据 2 级牙制订。 无无 沟沟 丝丝 攻攻 钻钻 孔孔 径径 规规 格格标标准准径径 2 级级牙牙钻钻孔孔径径 规规 格格标标准准径径 2 级级牙牙钻钻孔孔径径 规规 格格 精精 度度 等等 级级 最最 大大最最 小小最最 大大最最 小小G4-G6 G7-G8 M1.00.250.750.7850.729M121.011.0011.15310.917M1.00.250.860.88 M1.10.250.850.8850.829M120.511.5011.52011.400M1.10.250.960.98 M1.20.250.950.9850.929M141.512.5012.67612.376M1.20.251.061.08 M1.40.31.101.1421.075M141.013.0013.15312.917M1.40.31.241.25 M1.60.351.251.3211.221M151.513.5013.67613.376M1.60.351.411.43 M1.70.351.351.4211.321M151.014.0014.15313.917M1.70.351.511.53 M1.80.351.451.5211.421M161.514.5014.67614.376M1.80.351.611.63 M2.00.41.601.6791.567M161.015.0015.15314.917M2.00.41.781.80 M2.20.451.751.8381.713M171.515.5015.67615.376M2.20.451.951.98 M2.30.41.901.9791.867M171.016.0016.15315.917M2.30.42.082.10 M2.50.452.102.1382.013M182.016.0016.21015.835M2.50.452.252.28 M2.60.452.202.2382.113M181.516.5016.67616.376M2.60.452.352.38 M3.00.52.502.5992.459M181.017.0017.15316.917M3.00.52.732.75 M3.00.62.402.4402.280M202.018.0018.21017.835M3.50.63.173.20 M3.50.62.903.0102.850M201.518.5018.67618.376M4.00.73.623.65 M4.00.73.303.4223.242M201.019.0019.15318.917M5.00.84.564.60 M4.00.753.253.3263.106M222.020.0020.21019.835M6.01.05.455.50 M4.50.753.803.8783.688M221.520.5020.67620.376M7.01.06.456.50 M5.00.84.204.3344.134M221.021.0021.15320.917M8.01.257.317.38 M5.00.94.104.1703.930M242.022.0022.21021.835M101.59.189.25 M6.01.05.005.1534.917M241.522.5022.67622.376M101.259.319.38 M7.01.06.006.1535.917M241.023.0023.15322.917M121.7511.0411.12 M8.01.256.806.9126.647M252.023.0023.21022.835M121.2511.3111.38 M9.01.257.807.9127.647M251.523.5023.67623.376 注：无槽沟丝攻之钻孔径，在上表所列 之数值，由于被加工材料之材质、 硬度、形状、尺寸等这影响，多少 会有所变动，因此于参考上表之同 时，亦请增减若干。 M101.58.508.6768.376M251.024.0024.15323.917 M111.59.509.6769.376M261.524.5024.67624.376 M121.7510.3010.44110.106M272.025.0025.21024.835 M142.012.0012.21011.835M271.525.5025.67625.376 M162.014.0014.21013.835M271.026.0026.15325.917 美美 制制 细细 牙牙 螺螺 纹纹 M182.515.5015.74415.294M282.026.0026.21025.835 M202.517.5017.74417.294M281.526.5026.67626.376 规规 格格 (UNC) 标标准准径径 2 级级牙牙钻钻孔孔径径 M222.519.5019.74419.294M281.027.0027.15326.917最最 大大 M243.021.0021.25220.752M303.027.0027.25226.752No.1-64(1.854)1.551.582 M273.024.0024.25223.752M302.028.0028.21027.835No.2-56(2.184)1.801.871 M303.526.5026.77126.211M301.528.5028.67628.376No.3-48(2.515)2.102.146 M301.029.0029.15328.917No.4-40(2.845)2.302.385 规规 格格标标准准径径 2 级级牙牙钻钻孔孔径径M322.030.0030.21029.835No.5-40(3.175)2.602.697 最最 大大最最 小小M321.530.5030.67630.376No.6-32(3.505)2.802.895 M1.00.20.800.8210.783M333.030.0030.25229.752No.8-32(4.166)3.403.530 M1.10.20.900.9210.883M332.031.0031.21030.835No.10-24(4.826)3.903.962 M1.20.21.001.0210.983M331.531.5031.67631.376No.12-24(5.486)4.504.597 M1.40.21.201.2211.183M351.533.5033.67633.3761/4 -
