Storage

The Simmonds standard range of nuts is based around the original Nylstop self-locking nut, renowned for its performance and reliability. Following large scale investment, Simmonds have evolved their capability to include production of innovative, high-precision bespoke nuts, cold forged specials and high precision screw machined parts, all available in a wide range of materials and coatings.

Applications - Engine brackets, wheel axle nut and any other application where a re-usable locking nut or cold forged special is required.

Nylstop Nut

The original Simmonds Nylstop nut incorporates a nylon collar within the nut as the primary locking mechanism. This allows the nut to lock on the bolt providing a much stronger hold than standard nuts. Nylstop nuts are re-usable up to 15 times without performance loss.
