style="text-indent:25px">螺栓：一般沉頭用在要求連接后表面光滑沒突起的地方，因為沉頭可以擰到零件里。圓頭也可以擰進零件里。方頭的擰緊力可以大些，但是尺寸很大。另外為了滿足安裝后鎖緊的需要，有頭部有孔的，桿部有孔的，這些孔可以使螺栓受振動時不至松脫。有的螺栓沒螺紋的光桿要做細，叫細腰螺栓。這種螺栓有利于受變力的聯(lián)結(jié)。鋼結(jié)構(gòu)上有**的**度螺栓，頭部會做大些，尺寸也有變化。另外有特殊用處的：T形槽螺栓用，機床夾具上用的較多，形狀特殊，頭部兩側(cè)要切掉。地腳螺栓，用于機器和地面連接固定的，有很多種形狀。U形螺栓，如前述。等等。還有焊接用的**螺柱，一頭有螺紋一頭沒，可以焊在零件上，另一邊直接擰螺母。</p><p style="text-indent:25px">螺栓為什么要兩端倒角呢？倒角是機械工程上的術(shù)語.比如說在一塊木板上鉆眼,完成后孔壁和板面為90度直角。倒角就是在那個90度的棱上面再弄一個一般為45度的小平面,這樣這個平面和內(nèi)壁,或者和板面之間就都是45度了。這樣做的好處是使在向孔里插東西的時候不至于被卡住,更方便些。那么螺栓為什么要兩端倒角呢，好處是什么。下面小編要為大家介紹一下了。一、螺栓兩端倒完角以后可以去掉刻料時的翹角，在一定程度上可以降低螺栓與螺母鏈接時更順暢的擰入到螺栓里，尤其是細扣螺栓必須要兩端倒角。二、螺栓倒角以后外觀上更好更精致，深受客戶的歡迎。螺栓：S

style="text-indent:25px">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。螺栓是利用物體的斜面圓形旋轉(zhuǎn)和摩擦力的物理學(xué)和數(shù)學(xué)原理，循序漸進地緊固器物機件的工具。螺栓的標記可簡化為：螺栓DIN912/ISO4762/GB70還可進一步簡化為：DIN912/ISO4762/GB70常用緊固件的標記示例可查閱有關(guān)產(chǎn)品標準。當產(chǎn)品標準中只規(guī)定一種產(chǎn)品型式、性能等級或硬度或材料、產(chǎn)品等級、扳擰型式及表面處理時，允許全部或部分省略。沉頭螺絲又被稱為平機螺絲。四川尼龍螺栓</p><p style="text-indent:25px">螺栓按螺紋的牙型分為粗牙和細牙兩類。沉頭方頸螺栓</p><p style="text-indent:25px">鍍鋅六角螺栓就是在普通的六角螺栓的基礎(chǔ)上再經(jīng)過酸洗、脫脂、助鍍劑等工藝的處理，經(jīng)過這些工藝流程后，它比普通的六角螺栓更耐用，防銹性能更強，韌性更高。不過在經(jīng)過鍍鋅之后，它的螺紋擰合會變得難度增加，想要解決這個問題，可以在螺栓進行鍍鋅之后回攻，從而留出一定的間隙。不過回攻也會破壞掉螺栓螺紋表面的鍍層，導(dǎo)致里面的材料暴露，影響螺栓的耐腐蝕性能，這就難免導(dǎo)致加工的精度下降。很多螺栓生產(chǎn)廠家希望從鍍鋅工藝上面進行考慮，看看是否可以很好的改善擰和難度大的問題，比如調(diào)整浸鍍的時間和溫度，但是從嘗試的結(jié)果來看并不理想。沉頭方頸螺栓</p><p
