4-Hole Security Machine Screws

4 Hole Security Bolts & Screws have 4 location holes in the head section that are surrounded by a slim circular groove, requiring a special tool to tighten or remove. This unique feature provides a tamper proof fixing, reducing the risk of vandals or intruders tampering or undoing the screws.

• Vandal resistant 2-way security fixing with unique 4 hole system
• Tamper resistant re-usable security fixing
• Requires special driver tool (can be registered if required)
• Ideal for low to medium torque applications

4 hole security bolts and screws are typically used in design specific applications such as stainless steel architecture, balustrading and glass panels, and are specified by architects due to the pleasing aesthetics.

The standard 4-hole screw is ideal for lower security resistance where maintenance is required but the overall look of the job is more important.
