style="text-indent:25px">螺栓是指普通粗牙螺紋。知識(shí)擴(kuò)展：1、普通螺栓與**螺栓的區(qū)別：栓的等級(jí)分為4.8級(jí)、8.8級(jí)、9.8級(jí)、12.9級(jí)，普通螺栓就是4.8級(jí)的螺栓，其余的統(tǒng)稱(chēng)為**螺栓；強(qiáng)度等級(jí)與螺紋直徑無(wú)關(guān)。2、什么是**螺栓：用**度鋼制造的，或者需要施以較大預(yù)緊力的螺栓，皆可稱(chēng)為**度螺栓。**度螺栓多用于橋梁、鋼軌、高壓及超高壓設(shè)備的連接。這種螺栓的斷裂多為脆性斷裂。應(yīng)用于超高壓設(shè)備上的**度螺栓，為了保證容器的密封，需要施以較大的預(yù)應(yīng)力。常用螺栓生產(chǎn)廠家</p><p
