How Locking Nut Technology Works

Disc-Lock Nuts are two and three-piece nuts that utilize the same cam wedge locking technology: when the joint is subjected to heavy shock or vibration, the interlocking cams create a wedge effect because the cam angles are greater than the thread pitch, securing the joint.
