其實(shí)它還有一種叫法是sheet metal screws，大家一看應(yīng)該就明白了，中文就是薄鐵皮螺絲。這也就是他的主要用途，它是用在連接較薄的鐵質(zhì)物件上的，如薄鐵皮、鋁合金之類的。自攻螺釘有各種頭型，較常用的就是沉頭和盤頭，絕大多數(shù)都是蘭鋅的。為什么說(shuō)他不適用于木頭，因?yàn)樽怨メ數(shù)穆菁y較淺，用于木頭尤其是刨花板之類的無(wú)法提供足夠的張力。而鐵質(zhì)物件由于硬度很高，對(duì)于螺紋較淺的螺絲像自攻釘就可以提供足夠的張力。還有一個(gè)原因就是螺絲擰入時(shí)被連接件會(huì)形成螺紋孔，螺紋越淺則變形量越小，像鐵這樣的硬物在有足夠張力的情況下肯定是變形量越小越容易擰入。螺釘通?？呻S意移除或重新嵌緊而不損其效率。十字盤頭自攻釘品牌</p><p style="text-indent:25px">隨著市場(chǎng)的拓寬和新的應(yīng)用，強(qiáng)調(diào)新的設(shè)計(jì)，提高了自攻螺釘應(yīng)用性能。十字盤頭自攻釘品牌</p><p style="text-indent:25px">其它型式為平頂凹承面( Flat Undercut ), 平頂整緣( Flat Trim), 扁圓凹承面( Oval Undercut ), 扁圓整緣( Oval Trim )及圓柱頭(崗山頭Fillister )為比較次要頭型, 而香頂埋頭.螺紋滾成自攻螺絲（自攻釘）頭型之選擇與上同, 使用主要考慮菇頭( Truss ), 圓頭( Round )及100度平頂埋頭為新設(shè)計(jì)所不取,蓋其功用可為其它頭型所取代,盤頭可取代香菇頭及圓頭, 82度平頂埋頭可取代100度平為平頂,扁圓頂,盤頭,六角頭及六角華司頭五種。自1914年自攻螺絲開始商品化。一次之設(shè)計(jì)─主要源自木螺絲─系屬可滲碳鋼錐尾甲型螺紋成型螺絲。當(dāng)時(shí)主要之用途是用在空調(diào)系統(tǒng)導(dǎo)管上鐵皮之接合，因此又叫做鐵皮螺絲。經(jīng)過(guò)80余年之發(fā)展，共可分為四個(gè)時(shí)期─螺紋成型，螺紋切削，螺紋滾成及自鉆。十字盤頭自攻釘品牌</p><p
