Round Head Tamper Proof Self Tapping Clutch Head Screws
Clutch Head Screws are permanent, tamper-resistant screws that require only a slotted screwdriver to fit. Their unique head makes these screws an ideal security fastener for one way, permanent applications.
Most commonly found in public areas such as commercial toilet facilities, where maintenance is not required – but security is essential to prevent vandals tampering.
They provide an excellent, permanent solution for mass usage, but can be time-consuming to install. When fast installation is essential, we can also offer the Sentinel Security Screw.
Also referred to as clutch drive, one way round screws and perma screws, these screws are 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.
