钢丝螺套是一种新型内螺纹紧固件,它是由高强度、高精度、高表面质量的耐蚀菱形截面的钢丝绕制而成,形如弹簧。钢丝螺套装入螺孔中,钢丝螺套的外表面靠弹力贴合在螺孔上,其内表面形成新的螺纹,用于拧入螺钉或螺栓,使螺钉或螺栓不直接与基体接触,保护了基体及螺钉,起到延长螺纹使用寿命、增加螺纹连接强度、增大螺纹受力面、增加螺纹连接的承载力和抗疲劳强度、抗震防松脱等作用。在铝、镁合金等低强度工程材料上应用可以明显提高螺纹强度和耐磨性,同时钢丝螺套还改善了螺纹的受力情况,使螺纹整体用力,提高了螺纹联接的强度。钢丝螺套也可用于修复磨损或损坏的内螺纹孔。 
  钢丝螺套和自攻螺套产品一样,在航空、航天器、船用、车用动力机械,液力传动机械,风动工具,气动元件、化纤、纺织、烟草机械、光学仪器、电器、高压开关、汽车修理等行业的产品和设备上得了普遍应用。
