Pack of 25.

Mainly for use as anti-vandal fastener that can be used internally and externally. A low cost way of deterring thieves and vandals whether being used on access hatches, outside storage or anything you are wanting to look after.  

Clutch head security screws (one way security screws) feature a specially shaped drive, enabling them to be fastened using a standard slotted screwdriver.

The design of the drive slot ensures that they can only be turned in a clockwise direction; if the screw driver is turned anticlockwise it will not remove the screw and will instead simply “slip off”.

These screws require a special driver insert bit.
