Security Hex - Raised Countersunk Machine Screw - Stainless Steel (A2)

3.5mm Tamper Resistant Security Hex Raised Countersunk Machine Screw that`s used mainly for security electrical switch and socket face plates to back boxes. 

Security Hex is also called Pin Hex due to the additional security pin at the centre of the screw head recess. This makes it impossible to tamper with these screws without the aid of appropriate tooling which is why these screws are ideal for securing electrical equipment.

Security Hex screws also called Pin Hex Screws, are available from stock in A2 Stainless Steel and in a wide range of sizes and types including this 3.5mm Raised Countersunk Head Machine Screw.

The use of 3.5mm Tamper Proof Electrical Screws to secure 240v switch and socket faceplates, is typically specified as part of the safety strategy and policy in; schools, hospitals and public buildings among others.

Replacing the standard faceplate screws supplied with 13amp sockets and lightswitch faceplates with Anti Tamper Security Screws such as the 3.5mm raised countersunk equivalent, will help prevent unauthorised access to the electrical wiring ...increasing safety & security

The standard slotted faceplate retaining screw, is a 3.5mm machine screw featuring a raised countercunk head and is available in various lengths - and as the tamperproof electrical screws are available in lengths up to 75mm (for 75mm screw length see Security Torx Raised Countersunk Head Machine Screw), there is bound to be one to meet your needs.

There are many places where you may want to prevent unskilled or unauthorised persons from tampering with the wiring at your electrical sockets and lightswitches (ie: curious or malicious pupils in the school environment, the DIY member of staff trying to be helpful in the workplace, etc), fortunately there is a simple solution.
