1.從原材料看，**度螺栓采用**度材料制造。**螺栓的螺桿、螺帽和墊圈都由**鋼材制作，常用 45號鋼、40硼鋼、20錳鈦硼鋼。普通螺栓常用Q235鋼制造。 </p> <p> <br /> </p> <p> 2.從強度等級上看，**螺栓，使用日益普遍。常用8.8s和10.9s兩個強度等級，其中10.9級居多。普通螺栓強度等級要低，一般為4.4級、4.8級、5.6級和8.8級。 </p> <p> <br /> </p> <p> 3.從受力特點來看，普通螺栓連接靠栓桿抗剪和孔壁承壓來傳遞剪力，而**螺栓除了其材料強度很高之外，還給螺栓施加很大預拉力，使連接構件間產生擠壓力，從而使垂直于螺桿方向有很大摩擦力。 </p> <p> <br /> 螺栓的型號和螺母的型號怎么對應？樂山螺栓商家</p><p style="text-indent:25px">螺栓的符號表示有哪些？三門峽美標螺栓</p><p style="text-indent:25px">普通螺栓按照制作精度可分為A、B、C三個等級，A、B級為精制螺栓，C級為粗制螺栓。對于鋼結構用連接螺栓，除特別注明外，一般為普通粗制C級螺栓。不同的級次加工的方法存在差異，通常對應加工方式如下：①A、B級螺栓的栓桿由車床加工而成，表面光滑，尺寸精確，其材料性能等級為8.8級，制作安裝復雜，價格較高，很少采用;②C級螺栓用未加工的圓鋼制成，尺寸不夠精確，其材料性能等級為4.6級或4.8級?？辜暨B接時變形大，但安裝方便，生產成本低，多用于抗拉連接或安裝時的臨時固定。三門峽美標螺栓</p><p
