Keyserts are solid，one-piece，key-locking inserts used to repair damaged threads or for use in original equipment。
Keysert是一種堅固的一體式鍵鎖螺套，常用來修復損壞的螺紋或者在一些設備中作為初始裝備使用。
The Keysert locking keys provide a positive mechanical lock which prevents rotation due to vibration or torsion。
Keysert的插銷鍵可以提供一個強力的機械鎖以阻止工件因振動或扭力而發生旋轉。
