Stainless steel security screws in A2 (304) and A4 (316), for public places and anywhere fixings must resist tampering.
- Pin hex and six lobe pin screws have a centre pin in the drive, so a standard hex key or Torx driver will not fit.
- One-way screws can be tightened but not undone with ordinary tools.
- Two-hole (snake eye) screws need a matching two-pin driver.
Security screws only protect a fixing if the driver is kept away from the public, so keep the matching bit with the installer. Choose A4 for coastal and marine sites.
Sizes, grades and pack quantities vary by product type. Check the individual product listing for the exact specification and current availability.
