7 Lobe Pin Button Security Screws

A vandal resistant 7-Lobe Pin Security Screw, hosting a unique 7-Lobed TX Head that requires a special driver bit for insertion. This bit is registered to restrict and control availability.

With unique features, the 7-Lobe Pin Security Screw is tamper proof, reducing the risk of vandals or intruders tampering with or undoing the screws.

The design is suitable for higher torque applications and is a two way re-usable fixing.

Considered an upgrade from its predecessor, the 6-Lobe TX Security Screw, this 7-Lobe screw provides a higher degree of security as the driver bits are limited solely to distributors of the screw.

  • Enhanced security
  • Limited distribution
  • Restriction of supply of driver bits
