cap screw與大六角螺栓Hex bolt 顧名思義為頭部為六角型的外螺紋扣件，設(shè)計(jì)為使用扳手轉(zhuǎn)動(dòng)。依照ASME B18.2.1標(biāo)準(zhǔn)，六角頭螺釘(Hex cap screw)較一般的大六角螺栓(Hex bolt)的頭高和桿長(zhǎng)公差小，因此ASME B18.2.1六角螺釘適合安裝在所有六角螺栓可以使用的地方，也包含大六角螺栓太大而不能使用的地方。內(nèi)六角頭螺釘Socket cap screw 亦稱窩頭螺釘或亞倫螺栓(Allen bolt)，是頭部有一個(gè)六角型內(nèi)孔的螺釘，以六角尺(hex key, Allen wrench or Allen key)插入內(nèi)孔后才能擰緊或松動(dòng)。內(nèi)六角螺釘常使用的是圓柱頭螺釘，頭徑約螺紋主要直徑的 1.5倍 (1960系列)，其他頭型包括使表面美觀的半圓頭螺釘(Bottom head cap screw)和適用于錐形螺絲孔的平頭螺釘(Countersunk head cap screw)。沉孔設(shè)計(jì)允許螺釘頭不需要外露在被固定的物件表面也還能夠轉(zhuǎn)動(dòng)了，故多使用在表面較小，傳統(tǒng)板手不便使用的地方。機(jī)器螺絲Machine screw 一般來(lái)說(shuō)為直徑少于¼英寸的螺釘(4#~12#)，通常為全牙且由起子轉(zhuǎn)動(dòng)，如一字開(kāi)槽，十字或內(nèi)六角等。 </p>

</p> <p> 螺絲有很多叫法，每個(gè)人的叫法可能都不同，有人叫成螺釘，有人叫成螺絲釘，有人叫成標(biāo)準(zhǔn)件，有人叫成緊固件。雖然有這么多叫法，但意思都是一樣的，都是螺絲。螺絲是緊固件的通用說(shuō)法。螺絲的原理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(jìn)地緊固器物機(jī)件的工具。不銹鋼螺絲發(fā)黑解決方法是什么？</p><div

自攻螺絲的種類是很多的，上面**羅列了一部分，而且隨著人們對(duì)螺釘需求量的變化，相信日后也會(huì)有更多種類出現(xiàn)。 </p> <p> <br /> </p> <p> 由于自攻螺絲的特殊性很強(qiáng)，因此它的用途十分普遍，它起到的作用也是很多其他螺釘不能夠代替的，一般自動(dòng)螺釘多用于薄的金屬板，比如鋼板和鋼板、鋸板和鋸板之間的連接，在連接的時(shí)候，需要對(duì)連接件制作出螺紋形的底孔，然后把自攻螺絲擰入到連接件的螺紋底孔當(dāng)中，自攻螺絲本身表面的硬度比較高，可以在連接件的螺紋底孔中可以吧把螺紋攻出，從而有效的達(dá)成連接件的連接。

組合螺絲是指一個(gè)螺絲配一個(gè)彈墊在配一個(gè)平墊通過(guò)搓牙，組合緊固在一起的組合件。而二組合螺絲是指一個(gè)螺絲只配一個(gè)彈墊或只配一個(gè)平墊，要嗎還可以只配一個(gè)花齒的二組合件。 </p> <p> 組合螺絲的電鍍 </p> <p> 一般情況下，組合螺絲的電鍍一般是指鐵的組合螺絲去電鍍。電鍍有分為環(huán)保的與非環(huán)保的。常用的組合螺絲電鍍顏色有環(huán)保彩鋅，環(huán)保蘭鋅，環(huán)保白鋅，環(huán)保鎳，紅彩，白鋅，白鎳等。十字槽組合螺絲，六角組合螺栓和自攻組合螺絲的用途，與相應(yīng)的十字槽螺絲，六角頭螺栓和自攻螺絲的用途相同。這些組合螺絲的主要特點(diǎn)是均配上相應(yīng)的墊圈，使用起來(lái)十分方便。
