Hardlock Nuts

Hardlock nuts resists loosing in all environments where vibration occurs.

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

They are a secure fastening solution – 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 vibration loosening threaded joints. They can also reduce subsequent maintenance and inspection costs.
