类别：钢丝螺套系列
全国咨询服务热线:136-8529-8863
钢丝螺套是一种新型的螺纹紧固件，分为普通型和锁紧型两种。是由高精度菱形截 面的不锈钢丝精确加工而成的一种弹簧状内外螺纹同心体。锁紧型是在普通型的基 增加钢、塑料等低强度的工程材料的螺纹孔中，能形成标准的M，并能分散应力保护 基螺纹，大大延长基体的使用寿命。另外，钢丝螺套还可以在原基础上的螺纹脱扣或乱牙时，作为修复手段，而不致造成整个基体报废，并且维修方便，快速经济。 我公司能按GJB119-86、HB6200～6202-89、Q/9D171-91、Q/9D176-92及/9Dn2-89《GJB内控标准》进行系列生产，并能成套提供装配、检修工具。 目前，钢丝螺套技术已广泛用于航空、航天、兵器、电器、依表、汽车运输、矿山冶金、建筑、水泵、化纤、化工等行业。对于特殊要求的螺套我公司可以研制，满足您的需要。 螺纹丝套(钢丝螺套）及配套丝锥、安装工具、专用塞规,轴承钢(GCr15轴承钢（线，棒材）。
