45號(hào)鋼、40硼鋼、20錳鈦硼鋼。普通螺栓常用Q235鋼制造。2.從強(qiáng)度等級(jí)上看，**螺栓，使用日益普遍。常用8.8和10.9兩個(gè)強(qiáng)度等級(jí)，其中10.9級(jí)居多。普通螺栓強(qiáng)度等級(jí)要低，一般為4.4級(jí)、4.8級(jí)、5.6級(jí)和8.8級(jí)。3.從受力特點(diǎn)來看，普通螺栓連接靠栓桿抗剪和孔壁承壓來傳遞剪力，而**螺栓除了其材料強(qiáng)度很高之外，還給螺栓施加很大預(yù)拉力，使連接構(gòu)件間產(chǎn)生擠壓力，從而使垂直于螺桿方向有很大摩擦力。</p><p style="text-indent:25px">螺栓主要用于連接機(jī)械的固定連桿功能。螺栓兩端有螺紋，中間的螺釘又厚又薄。粗的稱為粗桿或A型，薄的稱為細(xì)桿或B型。一般用于礦山機(jī)械、橋梁、汽車、摩托車、鍋爐、鋼結(jié)構(gòu)、吊塔、大跨度鋼結(jié)構(gòu)和大型建筑物。主要用于連接厚度過大而不能使用螺栓或因頻繁拆裝而不宜使用螺栓的零件。通常螺栓的一端擰入螺孔，另一端用螺母連接。等長螺栓兩端均配有螺母。當(dāng)主體是大型設(shè)備時(shí)，需要安裝附件，如鏡子、機(jī)械密封座、減速器框架等。這是使用的螺栓。一端擰入主體，另一端在附件安裝后安裝螺母。由于附件經(jīng)常被拆下，螺紋會(huì)磨損或損壞，因此更換螺栓非常方便。<span
