style="text-indent:25px">自攻螺絲是一種帶有鉆頭的螺絲，通過**的電動(dòng)工具施工，鉆孔、攻絲、固定、鎖緊一次完成。重慶十字盤頭自攻自鉆螺釘</p><p style="text-indent:25px">自攻自鉆螺絲是把絲錐和螺栓結(jié)合起來了。前面是絲錐，后面是螺紋。在一般軟一些的材料上，鉆好一個(gè)空就可以直接擰入了。由絲錐攻出螺紋，緊接著螺栓螺紋吃勁兒。如果螺絲直徑較小，材料也非常軟。甚至可以不用先打孔，比如擰到木頭里。自攻自鉆螺絲通常用螺釘直徑級(jí)數(shù)、每英寸長度螺紋數(shù)量及螺桿長度三個(gè)參數(shù)來描述。螺釘直徑級(jí)數(shù)有10級(jí)和12級(jí)兩種，其對(duì)應(yīng)螺釘直徑分別為4.87mm和5.43mm；每英寸長度螺紋數(shù)量有14、16、24三種級(jí)別，每英寸長度螺紋數(shù)量越多，其自鉆能力越強(qiáng)。重慶十字盤頭自攻自鉆螺釘</p><p
