常用螺栓实用标准规格表.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阀口B级的六角头螺栓.A级用于D<=24和L<=10D或L<=150mm（e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400X0.6=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>;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1000X0.9=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。
