Hardlock Nuts have been used successfully in many applications worldwide for more than a decade. They have been used across many industries including railways, civil engineering, telephone, radar and power masts, towers and pylons, wind turbine towers and masts.

Hardlock Nuts are a secure fastening solution since the nuts do not come loose, even in the most severe vibration. 

By using Hardlock Nuts, engineers can be safe in the knowledge they are protecting expensive machinery and structures from the effects of vibrations loosening threaded joints. They can also reduce subsequent maintenance and inspection costs.

We have conducted vibration tests to demonstrate how Hardlock Nuts compare to other nuts in the fasteners market. All the tests have been conducted to DIN 65151. It is a dynamic test of the locking characteristics of fasteners under transverse loading conditions.
