- Unique external non-slip drive head
- Requires special driver tool to insert and remove
- Self-tapping security screw
- Medium security resistance
- Reusable 2-way drive
- Usable for higher torque applications
The tamper resistant System Zero self-tapping security screw has an external non-slip drive built into the head, and requires a special insert bit or key wrench to insert and remove.
Suitable for higher torque applications, these are 2 way reusable fixings, ideal for applications where maintenance is required.
The System Zero drive is designed to reduce and resist cam-out, which can occur more frequently in Phillips and 2-hole drives. The torx drive also allows for better torque, resulting in a screw which reduces the risk of damage to either the drive head or the application it is being used on.
Manufactured from Steel and A2 Stainless Steel as standard. Available at Fastenright in thread sizes from No.2 to No.14.
