                Hardlock Bearing Nut (HLB)
The HARDLOCK Bearing Nut was developed with the same wedge design as HARDLOCK Nut and maintains an extremely effective self-locking effect. The HARDLOCK Bearing Nut's high self-locking effect allows it to maintain a complete tightened state even during high-speed rotation, vibration, forward and reverse rotation and impact. We promise a significant cost down since it is maintenance-free.

The HARDLOCK Set Screw is a revolutionary self-locking set screw (Hexagon socket head set screw) which applies the "wedge principle" and delivers superior self-locking effect like the other HARDLOCK products without any change in the current conditions of the application.
