【标准】常用螺栓的标准及规格表.docx

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，其余通称为一般螺栓；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 4000.6=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 10000.9=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分，其性能是相同的，设计上只选用性能等级即可；精品文档沟通常 用 螺 丝 规 格 表类 规格 牙距别成品外径 线径类最大 最小 0.02mm 别牙数规格 〔 每英寸〕成品外径 线径 最大 最小 0.02mmM1.4 0.30 1.38 1.34 1.16 1/8 40 3.145 3.03 2.70M1.7 0.35 1.68 1.61 1.42 5/32 32 3.945 3.795 3.38M2.0 0.40 1.98 1.89 1.68 3/16244.7324.5924.00M2.3 0.40 2.28 2.19 1.98 英 1/4206.326.1655.45M2.5 0.45 2.48 2.38 2.15 制 5/16187.9057.7376.94M3.0 0.50 2.98 2.88 2.60 粗 3/8169.499.3128.40M3.5 0.60 3.47 3.36 3.02 牙 7/161411.0710.889.84M4.00.703.983.833.401/21212.6612.4611.22M4.50.754.474.363.889/161214.2514.0412.81M5.00.804.984.834.305/81115.8315.6114.27M6.01.005.975.825.184#402.8242.6952.37M7.01.006.976.826.185#403.1543.0262.6955 国标粗牙60 M8.0 1.25 7.96 7.79 7.02 6# 32 3.484 3.333 2.91M9.0 1.25 8.96 8.79 8.01 8# 32 4.142 3.991 3.57M10 1.50 9.96 9.77 8.84 美 10#244.84.6184.05M111.5010.9710.739.84制12#245.4615.2794.70M121.7511.9511.7610.7粗1/4206.3226.1175.45M142.0013.9513.7412.5牙5/16187.9077.6876.93M162.0015.9515.7414.560 3/8169.4919.2548.40M182.5017.9517.7116.27/161411.0810.829.83M202.5019.9519.7118.21/21312.6612.3911.32M4.00.503.973.863.589/161214.2513.9612.80M4.50.504.474.364.075/81115.8315.5314.26M5.00.504.974.864.574#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#364.1454.0063.63M9.0 1.00 8.97 8.83 8.24 美 10#324.8034.6514.23M10 1.00 9.97 9.82 9.23 制 12#285.4615.2964.81国标细牙60 M10 1.25 9.96 9.81 9.07M121.5011.9611.7910.8960 3/8249.4979.3158.74M141.5013.9613.7912.897/162011.0810.8710.18M161.5015.9615.7914.891/22012.6712.4611.76M181.5017.9517.7316.869/161814.2514.0313.25M201.5019.9519.6518.855/81815.8315.6214.83M12 1.25 11.97 11.76 11.07粗 1/4 28 6.324 6.16 5.68牙 5/16 24 7.909 7.727 7.16精品文档沟通类 规格别牙数 成品外径 线径牙数牙数M3.01.23.02.852.382#322.232.131.78M3.51.43.53.352.753#282.562.462.08类或 最大 最小 0.02mm 别牙数规格 或成品外径 线径最大 最小 0.02mm国4#242.892.792.285#203.303.202.606#183.583.452.781.64.03.853.151.84.54.353.4725.04.853.90标 M4.0 美76 M4.5 制60 M5.0 铁M6.02.56.05.854.67板7#164.013.863.10M2.0322.102.001.70A8#154.264.113.30M2.3322.402.301.95牙9#144.554.403.45M2.6282.702.602.1060 10#124.924.773.75M3.0243.103.002.4212#115.605.464.30M3.5183.653.502.8314#106.456.295.05M4.0164.154.003.252#322.232.081.78M4.5144.654.503.603#282.562.462.05M5.0125.205.004.00美4#242.892.742.28日制 A牙铁铁钉5#203.303.202.576#203.533.432.8060 M6.0 10 6.20 6.00 4.85 制M8.0 9 8.20 8.00 6.48 铁M2.0402.001.901.65 板7#193.913.783.13日 M2.3 32 2.30 2.20 1.85 AB 8#184.214.043.38制 M2.6 28 2.60 2.50 2.10 牙 10#164.804.653.80AB M3.0243.002.9060 2.4012#145.405.314.38牙 M3.5203.503.402.831/4146.256.055.18铁 M4.0184.003.853.25 墙板 6# 17 3.60 3.40 2.70M4.5钉164.504.353.60钉细7#164.003.753.03M5.0165.004.854.03牙8#154.304.053.2060 M6.0146.005.854.9560 10#124.954.703.72M8.0128.007.856.70墙板6#93.903.652.65M2.71.22.772.632.10钉粗7#94.203.902.90M3.11.33.173.032.40牙8#94.604.303.20日 M3.51.43.603.402.7560 10#85.304.903.70制 M3.81.63.903.703.00M2.5。
