basic information

Hard Rock (R) Nut, born in Japan and raised in the world Could the principle of a wedge be applied to prevent loosening? This theme was tackled, and after repeated trial and error, the Hard Rock Nut was completed. The inherent locking energy within it maintains a completely tightened state, unaffected by external vibrations or shocks. Currently, it continues to support safety as a fastening nut in various places, including railways, highways, bridges, skyscrapers, various industrial machinery, and public facilities. The strong anti-loosening effect, excellent workability, ease of attachment and detachment, and the maintenance-free economic benefits provided to users, which are not found in other locking nuts, are reflected in its high trust and track record. The Hard Rock Nut, born from the pursuit of safety, will continue to demonstrate its power in unseen places and protect the safety of society at large. □ For other functions and details, please download the catalog.
