Locking structure of the HARDLOCK NUT Locking structure of the traditional Japanese “Wedge� principle.
2 Wedge Principle Post (Nut) Beam (Bolt) Post (Nut)
1 By combining the Convex Nut designed with an eccentric conical protrusion 1 and the Concave Nut with its concentric conical depression 2 , due to the wedge priciple they will lock themselves onto the perpendicular axis of the bolt.
Due to the strong locking force created by the Wedge of the HARDLOCK NUT, no matter if it is exposed to severe vibrations or impacts the HARDLOCK NUT will stay intact!

The HARDLOCK NUT main features 1 An Anti- Loosening locking effect recognized by the world! 2 Available in various materials and surface treatments tailored to the environment!
3 Reusable without reduction in performance! 4 Full torque management and completely fastened even with zero (0) axial force!
5 Maintenance-free reduces total cost! 3

AFTER
Problem :
Solution :
1. Management at high tightening torque of 500N・m 2. Since nuts comes loose due to expansion and contraction of the rail, the inspection process required 3 people, 3 times a month. 3. The fishplate bolt broke frequently.
1. Easy management at low tightening torque of 250 - 300N・m 2. The need for inspection was reduced greatly with only 1 - 2 people once a month! 3. Bolts breaking was drastically reduced!
