High-strength fishtail bolt
Product Description
螺栓，機械零件，配用螺母的圓柱形帶螺紋的緊固件。螺栓：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，又可以使這兩個零件分開，故螺栓連接是屬于可拆卸連接。 按連接的受力方式分：分普通的和有鉸制孔用的。按頭部形狀分：有T形的，六角頭的，圓頭的，方形頭的，沉頭的等等。其中六角頭是常用的。一般沉頭用在要求連接的地方。應用非常廣泛。 ? ?螺栓有很多叫法，每個人的叫法可能都不同，有人叫成螺釘，有人叫成螺栓釘，有人叫成標準件，有人叫成緊固件。雖然有這么多叫法，但意思都是一樣的，都是螺栓。螺栓是緊固件的通用說法。螺栓的原理是利用物體的斜面圓形旋轉(zhuǎn)和摩擦力的物理學和數(shù)學原理，循序漸進地緊固器物機件的工具。?
螺栓在日常生活當中和工業(yè)生產(chǎn)制造當中，是少不了的，螺栓也被稱為工業(yè)之米?？梢娐菟ǖ倪\用之廣泛。螺栓的運用范圍有：電子產(chǎn)品，機械產(chǎn)品，數(shù)碼產(chǎn)品，電力設備，機電機械產(chǎn)品。船舶，車輛，水利工程，甚至化學實驗上也有用到螺栓。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、眼鏡、鐘表、電子等使用的微型螺栓;電視、電氣制品、樂器、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、電車、汽車等則為大小螺栓并用。螺栓在工業(yè)上負有重要任務，只要地球上存在著工業(yè)，則螺栓之功能永遠重要。
