Discover more about the Socket Button Head Captive Screws range.

Button Head Captive Screws are high-precision safety fasteners, which feature an unthreaded section below the head. This unthreaded section is designed to accommodate a Captive Washer, which locks in place during installation and prevents the screw from being fully removed from a target housing. Captive Screws are particularly useful for safety reasons, and are required by EU law on numerous pieces of equipment such as safety guards.

Accu can also offer a full range of alternative components in our Captive Screws range. For more information on the manufacture and applications of Accu's Captive Screw range, please see our What is a Captive Screw? page.
