Frequently Asked Questions

What are Anti-tamper fixings? These are fastenings that protect goods and property from thieves using conventional tools such as spanners and screwdrivers to undo threaded fixings. Within this group are security screws with anti-tamper heads including: – Clutch Head security screws

Security Torx Screws (aka Pin Torx Screws or Star Drive Screws) Pin Hex Screws (aka: Security Hex Screws) Snake Eye Screws (aka: Two Hole Screws, Pig Nose bolts or screws) Clutch Head screws (including the pozidriv type Sentinel One Way Screws).

“Proof” means it’s next to impossible. Tamper-resistant theory dictates a screw, bolt, or nut is designed to be installed and removed with a specialized tool made specifically for that fastener. It’s unlikely the average person wanting to loosen such a screw would have anything but ordinary tools available

If the application for your security screws is to achieve a permanent, non-removable fixing then one-way, clutch head screws, which are installed with a standard flat blade screwdriver, or Sentinel One-way screws which are installed with a standard Phillips / cross head screwdriver, would be a good choice

Security Screws are used for securing materials from being tampered with, such as gutters, license plates, grills in jails, schools, boats, and cars. They are also used in food prep and processing areas
