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 worldwide, possesses a strong anti-loosening effect, excellent workability, and ease of attachment and detachment that other lock nuts do not have. Could the principle of a wedge be applied to anti-loosening? This theme was tackled, and after repeated trial and error, the Hard Lock nut was completed.
