防盜(dao)(dao)螺栓，到底(di)怎么個防盜(dao)(dao)呢。其實(shi)防盜(dao)(dao)螺栓是能(neng)避免用管鉗等工具(ju)拆卸，而且年久松(song)動了也(ye)能(neng)重新加固。那么它是如何實(shi)現這一防盜(dao)(dao)效果的呢。

        其(qi)實防盜(dao)螺栓采用(yong)了錐(zhui)面(mian)(mian)外螺紋的設計，安裝(zhuang)時要(yao)與專(zhuan)用(yong)工(gong)(gong)具(ju)(ju)配(pei)合，只能順時針旋轉緊(jin)固(gu)，而(er)逆時針旋轉式則會(hui)造(zao)成工(gong)(gong)具(ju)(ju)的脫落(luo)。而(er)錐(zhui)面(mian)(mian)外形(xing)的設計有效避免了用(yong)管(guan)鉗拆卸，從(cong)而(er)起(qi)到防盜(dao)卸的效果(guo)。而(er)且就算年久松動了也能再次使(shi)用(yong)工(gong)(gong)具(ju)(ju)加(jia)固(gu)，使(shi)用(yong)壽命也很(hen)長(chang)。
