style="text-indent:25px">普通螺栓按照制作精度可分為A、B、C三個(gè)等級(jí)，A、B級(jí)為精制螺栓，C級(jí)為粗制螺栓。對(duì)于鋼結(jié)構(gòu)用連接螺栓，內(nèi)六角螺釘，除特別注明外，一般為普通粗制C級(jí)螺栓。不同的級(jí)次加工的方法存在差異，通常對(duì)應(yīng)加工方式如下： ①A、B級(jí)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(jí)為8.8級(jí)，制作安裝復(fù)雜，價(jià)格較高，很少采用; ②C級(jí)螺栓用未加工的圓鋼制成，尺寸不夠精確，其材料性能等級(jí)為4，內(nèi)六角螺釘，內(nèi)六角螺釘.6級(jí)或4.8級(jí)。抗剪連接時(shí)變形大，但安裝方便，生產(chǎn)成本低，多用于抗拉連接或安裝時(shí)的臨時(shí)固定。螺栓按照制作精度可分為A、B、C三個(gè)等級(jí)。內(nèi)六角螺釘</p><div
