簡單介紹
英制鋼絲螺套是一種新型的螺紋緊固件，是由高精度表面光潔的冷軋菱形不銹鋼絲**加工而成的一種彈簧狀內外螺紋同心體。鋼絲螺套還可以在原基體上的螺紋脫扣或亂牙時，作為修復手段，而不致造成整個基體報廢，并且維修方便，快速經濟。
英制鋼絲螺套的詳細介紹
英制鋼絲螺套簡介：
英制鋼絲螺套（簡稱螺套）是為保護有色金屬螺紋孔而發展的嵌入物，適用于螺紋連接。旋入并緊固在被連接件之一的螺紋孔中，形成標準內螺紋，螺栓（或螺釘）再擰入其中。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，具有較高的硬度及較好的表面粗糙度。
英制鋼絲螺套的作用：
英制鋼絲螺套主要用于螺絲孔的維修和要求較高的螺絲孔的制造。特別是在防止成本高昂的機器由于螺絲孔的損壞而無法正常使用方面，發揮著巨大作用。內螺紋常因種種原因而損壞，如脫扣、爛牙、磨損、腐蝕、生銹等等。內螺紋損壞有時會造成嚴重損失，輕者影響裝配過程和裝配質量，重者能造成整個大件報廢，鋼絲螺套為您提供了一套簡易而可靠的內螺紋修復方法，修補后的螺紋，將比原來的螺紋更加優越。對于強度較低的零件如鋁、鎂合金、銅、鑄鐵、鋼件、塑料、密度板和木材、玻璃鋼，這一點尤其明顯。安裝鋼絲螺套使用專用的絲錐及安裝工具攻絲和安裝，螺套裝于螺孔或螺母中，有減輕螺紋牙受力不均和抗沖擊振動的作用，可以提高螺紋的疲勞強度，減少螺紋的磨損和抗腐蝕性能。延長螺孔壽命。
