Security Screw

A security screw is a fastener with a head that needs a special tool to turn. It resists casual removal and is used where tampering is a concern.

A security screw fastens panels and covers that need restricted access. It often takes a matching driver bit or key. A nut and washer of the same thread and class can be used where the screw passes through.

Security screws are often made in stainless steel or carbon steel with a plating. Choose the material for the setting, since damp or coastal sites suit stainless steel.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and check the drive form and thread on receipt. Confirm the head shape matches the driver you hold, and inspect for damaged or rounded drives.
