螺栓按螺紋的牙型分為粗牙和細(xì)牙兩類，粗牙型在螺栓的標(biāo)志中不顯示。螺栓按照性能等級(jí)分為3.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9八個(gè)等級(jí)。 </p> <p> <br /> </p> <p> 其中8.8級(jí)以上(含8，泉州螺栓電話.8級(jí))螺栓材質(zhì)為低碳合金鋼或中碳鋼并經(jīng)熱處理(淬火+回火)，通稱**度螺栓，8.8級(jí)以下(不含8.8級(jí))通稱普通螺栓。 </p> <p> <br /> </p> <p>

**螺栓的施工必須先初擰后終擰，初擰**螺栓需用沖擊型電動(dòng)扳手或扭矩可調(diào)電動(dòng)扳手；而終擰**螺栓有嚴(yán)格的要求，終擰扭剪型**螺栓必須用扭剪型電動(dòng)扳手，終擰扭矩型**螺栓必須用扭矩型電動(dòng)扳手。 </p> <p>

六角頭螺栓分外六角螺栓和內(nèi)六角螺栓，是常用的緊固件，主要用作機(jī)械設(shè)備的緊固。無論是外六角還是內(nèi)六角，它們的規(guī)格尺寸表示方法都是類似的。外六角螺栓國家標(biāo)準(zhǔn)GB/T5782-86，這個(gè)標(biāo)準(zhǔn)規(guī)定了螺紋規(guī)格為M3~M64，A和B級(jí)的六角頭螺栓，A級(jí)用于D<=24和L<=10D或L。 </p> <p> <br /> </p> <p> 六角頭螺栓產(chǎn)品等級(jí)分為A、B、C三級(jí)，表示精度，其中A級(jí)精確，C級(jí)精度差。精度不同，作用的地方也不同，A級(jí)比B級(jí)高，要求高的地方用A級(jí)，大多數(shù)都選用B級(jí)。A級(jí)用于承載較大，要求精度高或受沖擊、振動(dòng)載荷的場(chǎng)合。 </p> <p> <br /> </p><p> 螺栓的材料即強(qiáng)度級(jí)別需在頭部頂面用凸字或凹字標(biāo)志，或在頭部側(cè)面用凹字標(biāo)志。包括性能等級(jí)、廠標(biāo)。強(qiáng)度等級(jí)標(biāo)記代號(hào)由“·”隔開的兩部分?jǐn)?shù)字組成。標(biāo)記代號(hào)中“·”前數(shù)字部分的含義表示公稱抗拉強(qiáng)度，如4.8 級(jí)的“4”表示公稱抗拉強(qiáng)度400N/MM2 的 1/100。標(biāo)記代號(hào)中“·”和點(diǎn)后數(shù)字部分的含義表示屈強(qiáng)比，即公稱屈服點(diǎn)或公稱屈服強(qiáng)度與公稱抗拉強(qiáng)度之比。 </p> <p> 螺栓：機(jī)械零件，配用螺母的圓柱形帶螺紋的緊固件。由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開，故螺栓連接是屬于可拆卸連接。螺栓的型號(hào)都有哪些表示方法？</p><div style="width:100%;text-align:

<br /> </p> <p> 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(hào)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(qiáng)度等級(jí)上看，**螺栓，使用日益普遍。常用8.8s和10.9s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)。 </p> <p> <br /> </p> <p> 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> <br /> 六角頭螺栓分外六角螺栓和內(nèi)六角螺栓，是常用的緊固件，主要用作機(jī)械設(shè)備的緊固。株洲**度螺栓</p><p
