Hardlock
The primary reason for bolts breaking is a drop from the initial tightening strength (axial force) of the screw, leading to a shortened life span and metal fatigue/breakage. That is to say that a low-cycle fatigue of the bolt is induced, which leads to failure. There are many products in the world that can prevent screws from falling out, but none that prevent them from becoming loose. At the time, there were no self-locking components that could prevent loss in the axial force.
We then focused on the idea of completely eliminating play in screws. Our initial manufacturing concept was a single lock nut that could be produced as inexpensively as possible. No matter how much we brainstormed, however, our assumptions and preconceptions blocked us from thinking outside the envelope because of our initial conditions and focus on the preventing screws from coming out.

Hardlock Nut (HLN)
Utilizing the wedge principle used in ancient Japanese architecture, the HLN is the ultimate self-locking nut which perfectly succeeds to integrate the nuts with the bolt.
-
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.

Hardlock Set Screw (HLS)
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.
