    鋼絲牙套

    鋼絲牙套又叫鋼絲螺套、螺套、螺紋襯套、螺紋護套、絲套,是為保護有色金屬螺紋孔而發展的嵌入物,以冷軋不銹鋼線制造成螺旋狀內外同心體螺紋線圈,橫切面呈菱形,形狀類似于螺旋彈簧。鋼絲牙套可以提高螺紋的疲勞強度,減少螺紋的磨損和抗腐蝕性能,從而延長螺孔壽命。

    鋼絲牙套產品簡介

             鋼絲牙套又叫鋼絲螺套、螺套、螺紋襯套、鋼絲牙套又叫鋼絲螺套、螺套、螺紋襯套、螺紋護套、絲套,是為保護有色金屬螺紋孔而發展的嵌入物,以冷軋不銹鋼線制造成螺旋狀內外同心體螺紋線圈,橫切面呈菱形,形狀類似于螺旋彈簧。鋼絲牙套可以提高螺紋的疲勞強度,減少螺紋的磨損和抗腐蝕性能,從而延長螺孔壽命。



    二、鋼絲牙套的用途

    1、增強連接強度、改善連接條件。

    2、耐磨損。

    3、增大受力面。

    4、防松脫。

    5、便于維修。
