Hard rock nut / hard rock bearing nut
HLN (Hard Lock Nut) / HLB (Hard Lock Bearing Nut)
The Hard Lock® nut, born in Japan and growing globally, possesses a strong anti-loosening effect not found in other lock nuts, along with excellent workability and ease of attachment and detachment. Could the principle of a wedge be applied to prevent loosening? This theme was tackled, and after repeated trial and error, the Hard Lock nut was completed.
