RS PRO Plain Button Stainless Steel Tamper Proof Security Screw, M4 x 12 mm


Part of our stringently tested RS PRO range, these tamper-proof security screws come with a unique head that makes them practically impossible to remove with regular tools. This makes them exceptionally useful in applications where you need to protect a structure, keep valuable compartments safe from vandals or thieves, or prevent wiring assemblies from being tampered with.

Manufactured from stainless steel, the screws have an M4 thread size and a pin-hex recess. In addition to providing increased security from tampering and theft, they've also been designed to protect builds against extreme weather conditions and adverse corrosion from rust.

The screws' button heads provide an additional layer of security because they can only be removed using a specific, matching tool. Tamper-proof security screws like these are commonly found in a wide range of applications – from numberplates and CCTV poles to rack mounting equipment and public bathroom fittings.
