Clutch Head C/sunk Self Tapping Security Screws

The Clutch Head Security Screw has a unique head that requires only a standard slotted screwdriver for insertion, making this the ideal security for one way permanent applications. Although the clutch head security screws provide an excellent permanent security solution for mass usage, they can be time-consuming to install.

Due to the design of vandal resistance Clutch Head Security Screw, it is suitable for medium torque applications. The unique drive system has a special chamfer at either side of the slotted drive enabling the screws to be turned in only one direction, so when turned anti-clockwise the tool simply slips out.

Commonly found in public areas such as commercial toilet facilities, where maintenance is not required but security is essential to prevent vandals tampering.

Tamper resistant Clutch Head security self tapping screws are available from Fastenright in Stainless Steel with other materials and sizes available to order.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
