Security Wave Nuts

A premium security nut with unique design, ideal for the highest security applications. Requires special driver tool to install.

  • Unique patented head design makes this a highly secure tamper proof nut
  • Driver tools can be stamped for full traceability
  • Re-usable and permanent security nuts available
  • Manufactured in the UK by the patent holder

Tamper resistant Wave nuts are a patented security fixing suitable for high torque applications. Most commonly used on applications requiring a high security solution, they are generally manufactured as a 2-way fixing but are also available in a permanent version.

Security Wave nuts have a unique design with varying angles and radii that resist against grips such as pliers.

Installed and removed using a special security Wave tool, which can be stamped and registered with a customer specific reference number. This ensures that, when used on site, each individual tool can be tracked and the personnel using the tool can also be registered against the tool for further traceability. The distribution of the tool is also restricted, so that only manufacturers and installers who have purchased the screws and have the registration number can purchase additional tools. Under no circumstances will tools be sold separately to ‘non-account’ customers.

These steel manufactured nuts can also be case hardened, which further enhances the security of the nut as it helps prevent hack sawing or chiselling the nut off. The case hardening process also provides the security Wave nut with up to 30% more torque.

Available from Fastenright in A1 Stainless Steel and A4 Stainless Steel as standard.

Thread diameters from M2 to M48, with other materials such as mild Steel, high tensile Steel and Plastic available to order. Imperial threads are also available on request.

Special Security Wave nuts can be made to order including various pitches in both small and large volume.
