Power in Safety

The anti-loosening Hard Lock Nut HL and Hard Lock Bearing Nut HLB employ the wedge principle to achieve a powerful locking energy not affected by shock or vibration. Both the Hard Lock Nut and the Hard Lock Bearing Nut are safe, easy to fasten and remove, and generally easy to use. They are also maintenance-free. The popularity of these products in industry has set Hard Lock apart from other hardware manufacturers.


Loosening Stopping NutThe Hard Lock Nut

The Hard Lock® Nut EBorn in Japan, Raised in the World


The Hard Lock Nut got its start when Hard Lock engineers began wondering if they could apply the principle of the wedge to hardware to prevent nuts from loosening. Through trial and error, they perfected this concept into a technology. The internal locking energy is completely unaffected by external shock and vibration, maintaining a completely fastened state.

Hard Locks products are used to ensure safety on railroads, expressways and bridges as well as in high-rise buildings, industrial machinery and public facilities.

No other locking nut has the anti-loosening power, ease of use including fastening and removal as Hard Locks nuts. Plus, they are maintenance-free. These economic advantages are reflected in the high level of trust and popularity that Hard Locks products have gained in industry.

Created in the pursuit of safety, the Hard Lock Nut proves its power by protecting the public in places invisible to the eye.
