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(guó)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。

螺栓檢測(cè)分為人工和機(jī)器兩種。人工是原始也是使用為普遍的一致檢測(cè)方式。為了盡量減少不良品的流出，一般生產(chǎn)企業(yè)人員通過目視的方式對(duì)待包裝或者發(fā)貨的產(chǎn)品進(jìn)行檢驗(yàn)，以排除不良品（不良包括牙傷、混料、生銹等）。 </p> <p> <br /> </p> <p> 另一種方式為機(jī)器全自動(dòng)檢測(cè)，主要是磁粉探傷。磁粉探傷是利用螺栓缺陷處的漏磁場(chǎng)與磁粉的相互作用，針對(duì)螺栓可能存在的缺陷（如裂紋，夾渣，混料等）磁導(dǎo)率和鋼鐵磁導(dǎo)率的差異，磁化后這些材料不連續(xù)處的磁場(chǎng)將發(fā)生崎變。 </p> <p> <br /> </p> <p> 形成部分磁通泄漏處工件表面產(chǎn)生了漏磁場(chǎng)，從而吸引磁粉形成缺陷處的磁粉堆積——磁痕，在適當(dāng)?shù)墓庹諚l件下，顯現(xiàn)出缺陷位置和形狀，對(duì)這些磁粉的堆積加以觀察和解釋，已達(dá)到剔除不良品的目的。 </p> <p> <br /> </p><p> 1、螺絲：螺絲為日常生活中不可或缺的工業(yè)必需品：如照相機(jī)、眼鏡、鐘表、電子等使用微型螺絲；電視、電氣制品、樂器、家具等之一般螺絲；至于工程、建筑、橋梁則使用大型螺絲、螺帽；交通器具、飛機(jī)、電車、汽車等則為大小螺絲并用。 </p> <p> <br /> </p> <p> 2、螺栓：螺栓在日常生活當(dāng)中和工業(yè)生產(chǎn)制造當(dāng)中，是少不了的，螺栓也被稱為工業(yè)之米。可見螺栓的運(yùn)用之普遍。螺栓的運(yùn)用范圍有電子產(chǎn)品，機(jī)械產(chǎn)品，數(shù)碼產(chǎn)品，電力設(shè)備，機(jī)電機(jī)械產(chǎn)品等等。 </p> <p> <br /> </p> <p> 3、螺帽（螺母）：主要用于汽車業(yè)--轎車，卡車，客車，壓縮機(jī)，建筑機(jī)械，風(fēng)力發(fā)電設(shè)備，農(nóng)用機(jī)械，緊固件，鑄造業(yè)，鉆孔設(shè)備。 </p> <p> <br /> 螺栓性能等級(jí)的含義鋼結(jié)構(gòu)連接用螺栓性能等級(jí)分幾種？</p><div

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？甘孜五金螺栓</p><p
