style="text-indent:25px">螺栓是指普通粗牙螺紋。知識(shí)擴(kuò)展：1、普通螺栓與高強(qiáng)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)稱為高強(qiáng)螺栓；強(qiáng)度等級(jí)與螺紋直徑無(wú)關(guān)。2、什么是高強(qiáng)螺栓：用高強(qiáng)度鋼制造的，或者需要施以較大預(yù)緊力的螺栓，皆可稱為高強(qiáng)度螺栓。高強(qiáng)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)備上的高強(qiáng)度螺栓，為了保證容器的密封，需要施以較大的預(yù)應(yīng)力。</p><p style="text-indent:25px">普通的螺栓按照制作精度可以分為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，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(chē)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4.6級(jí)或4.8級(jí)?？辜暨B接時(shí)變形大，但安裝方便，生產(chǎn)成本是比較低的，多用于抗拉連接或安裝時(shí)的臨時(shí)固定。螺栓緊固器物機(jī)件的工具。</p><div

style="text-indent:25px">螺栓在日常生活當(dāng)中和工業(yè)生產(chǎn)制造當(dāng)中，是非常重要的，螺栓也被稱為工業(yè)之米。可見(jiàn)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。船舶，車(chē)輛，水利工程，甚至化學(xué)實(shí)驗(yàn)上也有用到螺栓。反正是超多地方都有用到螺栓的。特如數(shù)碼產(chǎn)品上面用到的精密螺栓。DVD，照相機(jī)、眼鏡、鐘表、電子等使用的微型螺栓;電視、電氣制品、樂(lè)器、家具等之一般螺栓;至于工程、建筑、橋梁則使用大型螺栓、螺帽;交通器具、飛機(jī)、電車(chē)、汽車(chē)等則為大小螺栓并用。螺栓在工業(yè)上負(fù)有重要任務(wù)，只要地球上存在著工業(yè)，則螺栓之功能永遠(yuǎn)重要。螺栓M表示“公制，米制”螺紋。縮桿螺栓</p><p style="text-indent:25px">摩擦型高強(qiáng)度螺栓承受剪力的準(zhǔn)則是設(shè)計(jì)荷載引起的剪力不超過(guò)摩擦力。螺絲定制</p><p style="text-indent:25px">螺栓檢測(cè)分為人工和機(jī)器兩種。人工是較原始也是使用較為普遍的一致檢測(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(guò)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）。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，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。螺絲定制</p><p
