Description
Hot Dip Galvanised Shear Nut – Tamper-Proof Security Fastener
The Hot Dip Galvanised Shear Nut is a permanent security fastener designed for applications requiring maximum tamper resistance. Once installed, the hex section shears off at a pre-set torque, leaving a smooth, conical head that resists removal. The hot dip galvanised coating provides excellent corrosion protection for outdoor and industrial environments.
Applications
- Security fencing, gates, and bollards
