是在金屬或非金屬材料之預鉆孔中自行攻鉆出所配合陰螺紋之一種有螺紋扣件。自攻螺釘多用于薄的金屬板（鋼板、鋸板等）之間的連接。連接時，先對被連接件制出螺紋底孔，再將自攻螺釘擰入被連接件的螺紋底孔中。由于自攻螺釘?shù)穆菁y表面具有較高的硬度（≥45HRC），可在被連接件的螺紋底孔中攻出內(nèi)螺紋，從而形成連接。由于其自行成型或攻出其配合螺紋，因此在組合上具有高防松能力，且可以裝卸。在小形螺絲上其尺寸，螺紋型式，頭型，攻鉆性能在工程用途上幾乎無可限量。螺釘頭部形狀有圓頭，平頭，半沉頭及沉頭等。材料一般用滲碳鋼，熱處理后材料表面硬度不低于45HRC。與普通螺釘?shù)穆菁y相比，在相同的大徑時，其螺距大而小徑則稍小，已標準化。自攻螺釘材料可分為碳鋼和不銹鋼兩種，其中碳鋼材料通常用1022中碳鋼為主。江蘇自攻釘公司有哪些自攻釘和自攻自鉆釘雖然螺距大一些，但在型材壁厚大于螺紋公稱直徑的時，螺紋還是可以承受很大拉力的。</p><div

自攻釘?shù)倪x購：和干壁釘一樣，有些是通用的，比如槽要在頭**，不能偏心之類，這些都能從外觀上看出來。由于是用于金屬連接，自攻釘?shù)臋C械性能很重要，而這不是從外觀上能看出來的。常用的有表面硬度、芯部硬度、扭矩等，并且不能有氫脆，這些都需要專業(yè)測試。不過有一個判定質(zhì)量方法是大家可以用的，就是找個地方固定住螺絲，然后用錘子什么的敲，一般要求在螺絲彎到15度以內(nèi)不能斷，好的可以到30度甚至45度以上。或者用鉗子扭，扭不斷就是硬度較好的。接下來是用在木頭上的另一種螺絲，俗稱纖維板螺絲。纖維板螺絲可以分細牙和粗牙，帶筋和不帶筋。一般來說北半球國家用細牙不帶筋較多，而南半球國家用粗牙帶筋較多。</p><p

style="text-indent:25px">自鉆自攻螺釘與普通自攻螺釘不同之處是普通自攻螺釘在連接時，須經(jīng)過鉆孔（鉆螺紋底孔）和攻絲（包括緊固連接）兩道工序；而自鉆自攻螺釘在連接時，就將鉆孔和攻絲兩道工序合并一次完成。它先用螺釘前面的鉆頭進行鉆孔，接著就用螺釘進行攻絲（包括緊固連接），節(jié)約施工時間，提高施工效率。盤頭和六角頭自攻螺釘適用于鉆頭允許露出的場合，六角頭自攻螺釘可比盤頭自攻螺釘隨較大的力矩。沉頭和內(nèi)六角花形自攻螺釘適用于釘頭不允許露出的場合，內(nèi)六角花形自攻螺釘可比沉頭自攻螺釘承受較大的力矩；半沉頭自攻螺釘適用于釘頭允許輕微露出的場合。自攻螺釘?shù)难b拆時，開槽自攻螺釘需用一字形螺釘旋具，十字槽自攻螺釘需用十字形螺釘旋具，內(nèi)六角花形自攻螺釘需用內(nèi)六角花形扳手，六角頭自攻螺釘需用呆扳手、梅花扳手、套筒扳手或活扳手。目前國內(nèi)常用的自攻釘有十字沉頭和十字盤頭兩種類型的。江蘇高低牙自攻釘公司有哪些</p><p

螺絲有很多叫法，每個人的叫法可能都不同，有人叫成螺釘，有人叫成螺絲釘，有人叫成標準件，有人叫成緊固件。雖然有這么多叫法，但大體都是指螺絲。螺絲的原理是利用物體的斜面圓形旋轉(zhuǎn)和摩擦力的物理學和數(shù)學原理，循序漸進地緊固器物機件的工具。螺絲主要是按螺紋來分的，不同的螺紋決定了它用在什么地方，頭型什么都是通用的，合適即可。螺紋一般可粗分兩大類，一類就是下文即將介紹的各種螺絲，擰入時與被緊固件產(chǎn)生螺紋配合，配合螺紋在螺絲擰入時產(chǎn)生。還有一類是標準螺紋，由外螺紋緊固件（各種螺栓、機螺絲等）和內(nèi)螺紋件（螺母等）配合旋緊。自攻釘廠家有哪些</p><p
