4-Hole Security Nuts

4-Hole security nuts

Tamper resistant and aesthetically pleasing, 4-hole fixings are typically used in design specific applications such as stainless steel architecture, balustrading and glass panels.

  • Vandal Resistant 2 way security nuts with unique 4 hole fixing system
  • Tamper proof and reusable security fixing
  • Requires special driver tool (can be registered if required)
  • Ideal For low to medium torque applications

The 4 location holes in the head (face) section are surrounded by a slim circular groove, requiring a special tool to tighten or remove. This makes the nuts tamper proof, reducing the risk of vandals or intruders tampering or undoing the screws.

The 4-hole nut is mainly ideal for lower security resistance where maintenance is required but the overall look of the job is more important.

4 Hole Security nuts are available off the shelf in stainless steel but can be manufactured in other sizes and materials on request.
