常用螺栓的标准及规格表VIP专享VIP免费

常用螺栓的标准及规格表国家标准规定了螺纹规格为M3~M64,A和B级的六角头螺栓.A级用于D<=24和L<=10D或L<=150mm(按较小值)的螺栓;B级用于D>24或L>10D或L>150(按较小值)的螺栓外六角螺栓尺寸规格(如图)钢结构连接用螺栓性能等级分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余个等级，其中8.8级及以上螺栓材质为低碳合金钢或中碳钢并经热处理（淬火、回火），通称为高强度螺栓，其余通称为普通螺栓。螺栓性能等级标号有两部分数字组成，分别表示螺栓材料的公称抗拉强度值和屈强比值。例如，性能等级4.6级的螺栓，其含义是：1、螺栓材质公称抗拉强度达400MPa级；2、螺栓材质的屈强比值为0.6；3、螺栓材质的公称屈服强度达400×0.6=240MPa级性能等级10.9级高强度螺栓，其材料经过热处理后，能达到：1、螺栓材质公称抗拉强度达1000MPa级；2、螺栓材质的屈强比值为0.9；3、螺栓材质的公称屈服强度达1000×0.9=900MPa级螺栓性能等级的含义是国际通用的标准，相同性能等级的螺栓，不管其材料和产地的区别，其性能是相同的，设计上只选用性能等级即可。常用螺丝规格表类别规格牙距成品外径线径类别规格牙数(每英寸)成品外径线径最大最小±0.02mm最大最小±0.02mm国标粗牙60°M1.40.301.381.341.16英制粗牙55°1/8403.1453.032.70M1.70.351.681.611.425/32323.9453.7953.38M2.00.401.981.891.683/16244.7324.5924.00M2.30.402.282.191.981/4206.326.1655.45M2.50.452.482.382.155/16187.9057.7376.94M3.00.502.982.882.603/8169.499.3128.40M3.50.603.473.363.027/161411.0710.889.84M4.00.703.983.833.401/21212.6612.4611.22M4.50.754.474.363.889/161214.2514.0412.81M5.00.804.984.834.305/81115.8315.6114.27M6.01.005.975.825.18美制粗牙60°4#402.8242.6952.37M7.01.006.976.826.185#403.1543.0262.69M8.01.257.967.797.026#323.4843.3332.91M9.01.258.968.798.018#324.1423.9913.57M101.509.969.778.8410#244.84.6184.05M111.5010.9710.739.8412#245.4615.2794.70M121.7511.9511.7610.71/4206.3226.1175.45M142.0013.9513.7412.55/16187.9077.6876.93M162.0015.9515.7414.53/8169.4919.2548.40M182.5017.9517.7116.27/161411.0810.829.83M202.5019.9519.7118.21/21312.6612.3911.32国标细牙60°M4.00.503.973.863.589/161214.2513.9612.80M4.50.504.474.364.075/81115.8315.5314.26M5.00.504.974.864.57美制粗牙60°4#482.8772.7132.44M6.00.755.975.855.415#443.1573.0362.73M7.00.756.976.856.416#403.4843.3563.02M8.01.007.977.837.248#364.1454.0063.63M9.01.008.978.838.2410#324.8034.6514.23M101.009.979.829.2312#285.4615.2964.81M101.259.969.819.071/4286.3246.165.68M121.2511.9711.7611.075/16247.9097.7277.16M121.5011.9611.7910.893/8249.4979.3158.74M141.5013.9613.7912.897/162011.0810.8710.18M161.5015.9615.7914.891/22012.6712.4611.76M181.5017.9517.7316.869/161814.2514.0313.25M201.5019.9519.6518.855/81815.8315.6214.83类别规格牙数或牙数成品外径线径类别规格牙数或牙数成品外径线径最大最小±0.02mm最大最小±0.02mm国标76M3.01.23.02.852.38美制铁板2#322.232.131.78M3.51.43.53.352.753#282.562.462.08M4.01.64.03.853.154#242.892.792.28M4.51.84.54.353.475#203.303.202.606A牙60°M5.025.04.853.906#183.583.452.78M6.02.56.05.854.677#164.013.863.10日制A牙铁铁钉60°M2.0322.102.001.708#154.264.113.30M2.3322.402.301.959#144.554.403.45M2.6282.702.602.1010#124.924.773.75M3.0243.103.002.4212#115.605.464.30M3.5183.653.502.8314#106.456.295.05M4.0164.154.003.25美制铁板AB牙60°2#322.232.081.78M4.5144.654.503.603#282.562.462.05M5.0125.205.004.004#242.892.742.28M6.0106.206.004.855#203.303.202.57M8.098.208.006.486#203.533.432.80日制AB牙铁铁钉60°M2.0402.001.901.657#193.913.783.13M2.3322.302.201.858#184.214.043.38M2.6282.602.502.1010#164.804.653.80M3.0243.002.902.4012#145.405.314.38M3.5203.503....
