Security Wave Bolts

Tamper resistant security wave bolts & screws

A premium tamper proof bolt, ideal for the highest security applications.

  • Highly secure fixing, with unique patented head design
  • Available in stainless steel and steel (mild & HT) sizes M2 to M48
  • Security bolts for high torque applications
  • Driver tools can be stamped for full traceability
  • Re-usable and permanent anti-theft bolts available
  • Manufactured in the UK by the patent holder

Reusable or one-way security bolts

These tamper proof bolts can be supplied with either a 2-way reusable or 1 way permanent security drive. The unique rounded design incorporates varying angles and radiuses to resist against grips such as pliers, making it ideal for applications where the highest level of security is essential.
Tamper resistant security Wave bolts and screws are the perfect match with Security Wave nuts, and are also suitable for use with shear nuts, Kinmar reusable nuts, Kinmar permanent nuts, 4-hole nuts or pin torx barrel nuts.

Additional security with registered driver tools

Security Wave bolts require a special driver tool which can be stamped and registered with a customer specific reference number which 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. Distribution of the tool is restricted, meaning that only manufacturers and installers who have purchased the screws can purchase additional tools. Under no circumstances will tools be sold separately to ‘non-account’ customers.

Tamper proof bolts available to order

Security Wave bolts and screws are available to order with thread sizes from M2 to M48, with imperial threads also available on request. We can supply small volumes and custom parts to specification. A limited range of sizes are also available from stock, please ask for details.
Manufactured in A1 stainless steel, A4 stainless steel, mild steel and high tensile steel. The steel manufactured bolts and screws can also be case hardened, which further enhances the security of the bolt as it helps prevent hack sawing or chiselling the bolt off. This process also provides the security Wave bolt with up to 30% more torque.

There is no stock size chart for this product, although we do have a limited range of Wave security bolts in stock, please call for details.
