Tricone® Security Bolt

Tricone® Security Bolt – Patented Premium Security Fastener exclusively from Fastenright

Tamper proof bolt, as featured in Fastener and Fixings Technology Magazine, Oct 2014 (see article here)

  • Unique patented product (to Fastenright)
  • Every Tricone® driver tool is uniquely coded (traceable to customer)
  • High torque product
  • Polished head gives a shiny and aesthetic finish
  • Probably most secure fastener on the market
  • Only supplied to user customers and not permitted for re-sale

The Tricone® security screw, Fastenright’s patented premium security fastener has been developed to offer customers the highest possible security fixing for their products and applications.

The Tricone® security screw features a domed and polished head that has been designed to resist removal, whilst still providing a unique aesthetic appearance.

Three equally spaced blind holes are formed into the head and in their middle host a shaped cone projection which protrudes upwards from the hole’s base. The three-dimensional cones in each hole make forced removal of the fastener extremely difficult.

A dedicated locking and unlocking tool is required to fix and remove the fastener and because of the three pin system used, a high torque of the fastener is achievable.

The locking tool is fully hardened and each tool is uniquely coded, ensuring that our product is fully traceable down to the customer it is sold to – ensuring the integrity of this premium, high security fastener.

The bolts are manufactured in A2 Stainless Steel and currently available in M6, M8 and M10 thread with lengths of up to 100mm available. Other sizes form M4 can be manufactured to order.

Tricone® security tools are only available from Fastenright Ltd, and are only sold to end user customers who have purchased the screws and are not permitted for re-sale. This policy is vigorously enforced to ensure the continued high level of security for our product.

The Tricone® security screw is made from high quality A2 Stainless Steel and fully traceable in accordance with our ISO 9001:2008 certification.

*We have obtained full technical protection of the Tricone® range of fasteners and will defend any infringement of these rights vigorously.

Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
