Button Head Captive Screws are useful in a number of safety-oriented applications and are required by European Union law on some equipment such as safety guards.
They are high precision safety fasteners that host an unthreaded section below their head, which is often referred to as a reduced shank.
They are, once installed, unable to be fully removed from their installation hole.
Found across a number of types of industrial machinery, where a lost or loose screw could cause catastrophic damage to a production line. They can also be found in certain military applications where the speedy removal and reinstallation of panels is required.
Available as standard in A2 and A4 stainless, with specialist materials also available including brass and aluminium.
