1、Recoil
螺套产品的作用：主要用来保护母材中的螺纹，并分散工作载荷，减少应力集中提高母材螺纹的寿命。
2、Recoil螺套的类型：标准型
螺纹护套、自锁型螺纹护套、无尾型螺纹护套。自锁型螺纹护套除了具有螺纹护套的功能外，更可以起到防松的效果。
3、Recoil螺套的材料：304不锈钢、316不锈钢、磷青铜、INCONELX750、尼莫尼克90合金、尼莫尼克60合金等。
Recoil集团是世界上*早生产螺纹护套的厂家之一。Recoil集团不仅生产工业用紧固件，同时也是世界上*大的航空紧固件生产厂商。每一架空客和波音的飞机都使用这种紧固件。其螺纹护套产品在劳斯莱斯的航空引擎上也有应用。并且执行相同的质量体系，所以其螺纹护套产品也和航空用紧固件一样质量优良，同时价格适中。
Recoil螺套系统中，主要分公制螺套和英制螺套，下表为Recoil螺套公制规格 Recoil螺套公制编号 Recoil Metric Insert Part Number
