常用螺栓的标准及规格表

常用螺栓的标准和规格表在国家标准中，螺纹规格为M3M64、A和b等级的六角头螺栓。a额定值用于D=24和L=10D或L=150mm(按较小值)的螺栓。级别b用于D24或L10D或L150(按较小值)的螺栓外六角螺栓尺寸规格(图)钢结构连接的螺栓性能等级分为3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10多个等级，其中8.8以上螺栓材料为低碳合金钢或中碳钢，热处理(淬火、回火)为高强度螺栓性能等级标签由两部分组成，分别表示螺栓材料的公称拉伸强度值和屈服比值。例如，性能级别4.6的螺栓意味着：1、螺栓材料公称拉伸强度400MPa级；2、螺栓材料的降伏比值为0.6。3、螺栓材料的公称屈服强度达到4000.6=240MPa热处理后材料可以达到的性能水平10.9高强度螺栓：1、螺栓材料公称拉伸强度1000MPa水平；2、螺栓材料的降伏比值为0.9。3、螺栓材料的公称屈服强度达到10000.9=900MPa螺栓性能等级的含义是国际通用的标准，同一性能等级的螺栓的性能相同，无论其材料和原产地的差异如何，设计上只需选择性能等级即可。使用速度表类别规格牙齿距离成品的外径实线类别规格牙齿数(每英寸)成品的外径实线最大最小0.02mm最大最小0.02mm国家标记粗的牙齿60M1.40.301.381.341.16英国系统粗的牙齿55八分之一403.1453.032.70M1.70.351.681.611.425/32323.9453.7953.38M2.00.401.981.891.683/16244.7324.5924.00M2.30.402.282.191.98四分之一206.326.1655.45M2.50.452.482.382.155/16187.9057.7376.94M3.00.502.982.882.603/8169.499.3128.40M3.50.603.473.363.027/161411.0710.889.84M4.00.703.983.833.40二分之一1212.6612.4611.22M4.50.754.474.363.889/161214.2514.0412.81M5.00.804.984.834.305/81115.8315.6114.27M6.01.005.975.825.18美国系统粗的牙齿604#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#245.4615.2794.70M121.7511.9511.7610.7四分之一206.3226.1175.45M142.0013.9513.7412.55/16187.9077.6876.93M162.0015.9515.7414.53/8169.4919.2548.40M182.5017.9517.7116.27/161411.0810.829.83M202.5019.9519.7118.2二分之一1312.6612.3911.32国家标记去牙齿60M4.00.503.973.863.589/161214.2513.9612.80M4.50.504.474.364.075/81115.8315.5314.26M5.00.504.974.864.57美国系统粗的牙齿604#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#285.4615.2964.81M101.259.969.819.07四分之一286.3246.165.68M121.2511.9711.7611.075/16247.9097.7277.16M121.5011.9611.7910.893/8249.4979.3158.74M141.5013.9613.7912.897/162011.0810.8710.18M161.5015.9615.7914.89二分之一2012.6712.4611.76M181.5017.9517.7316.869/161814.2514.0313.25M201.5019.9519.6518.855/81815.8315.6214.83类别规格牙齿数或者牙齿数成品的外径实线类别规格牙齿数或者牙齿数成品的外径实线最大最小0.02mm最大最小0.02mm国家标记7660M3.01.23.02.852.38美国系统铁板块a牙齿602#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#203.303.202.60M5.025.04.853.906#183.583.452.78M6.02.56.05.854.677#164.013.863.10工作系统a牙齿铁铁钉钉子60M2.0322.102.001.708#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美国系统铁板块AB牙齿602#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工作系统AB牙齿铁铁钉钉子60M2.0402.001.901.657#193.913.783.13M2.3322.302.201.858#184.214.043.38M2.6282.602.502.1010#164.804.653.80M3.0243.002.902.4012#145.405.314.38M3.5203.503.402.83四分之一146.256.055.18M4.0184.003.853.25墙板细钉钉子牙齿606#173.603.402.70M4.5164.504.353.607#164.003.753.03M5.0165.004.854.038#154.304.053.20M6.0146.005.854.9510#124.954.703.72M8.0128.007.856.70墙板钉子很粗牙齿606#93.903.652.65工作系统树蜗牛丝绸60M2.71.22.772.632.107#94.203.902.90M3.11.33.173.032.408#94.604.303.20M3.51.43.603.402.7510#85.304.903.70M3.81.63.903.703.00德国标记(C/B)钉钉子40M2.51.12.52.251.80M4.11.84.204.003.20M3.01.353.02.752.10M4.524.604.403.50M3.51.63.53.202.45M4.82.14.924.683.70M4.01.84.03.702.78M5.12.25.224.983.95M4.524.54.203.10M5.52.45.625.384.30M5.02.25.04.703.45M5.82.65.925.684.45M6.02.66.05.704.20强度等级所谓的8.8和10.9等级表示螺栓的剪切应力等级8.8GPa和10.9Gpa，8.8公称拉伸强度800N/MM2公称屈服强度640N/MM2一般螺栓以X.Y表示强度，X*100=此螺栓的抗拉强度，X*100*(Y/10)=此螺栓的降伏强度(标识规定：降伏强度/抗拉强度=Y/10)在4.8级，此螺栓的拉伸强度为400 * 8/10=400MPa另外：不锈钢螺栓通常标记为A4-70、A2-70，其含义另作解释测量在当今世界，长度测量单位主要有两种：公制、厘米、毫米(mm)，常用于欧洲、我国、日本等东南亚地区；另一种常用于英国，测量单位主要用英寸(inch)，常用于美国旧品尝美国、英国等欧洲和美国。1，公制测量： (十进制)1m=100 cm=1000 mm2，英制数量： (八进制)1英寸=8字母数字1英寸=25.4毫米3/825.4=9.523、1/4以下的产品使用板弧表示其称号，如下所示：4#、5#、6#、7#、8#、10#、12#蜗牛首先，螺纹是均匀螺旋上升到固体外表面或内表面部分的形状。根据结构特征和用途，可分为三类。(a)，普通螺纹：用于连接或拧紧零件的牙齿是三角形。普通螺纹根据螺距分为粗齿和细齿螺纹，细齿
