Can be installed using an ordinary flat head screwdriver!
‘Clutch Head’ are ‘One Way Security Screws’ which are made of hardened steel with a bright zinc finish provide a permanent fixing, yet can be installed using an ordinary flat head screwdriver. The head of the screw has a normal drive face and a chamfered rear face which prevents a screwdriver from being able to unscrew them. Once installed, these screws will typically have to be drilled out to remove them, as the sloping cam on the head prevents any attempt to unscrew.
Size 8, 4.12mm diameter screw thread, 1″ (25mm) long.
