Clutch Head - Countersunk Self Tapping Screw - Stainless Steel (A2)

Clutch Head Countersunk Self Tapping Screws are manufactured from A2 grade stainless steel making them great for internal or outdoor projects. Clutch head screws are the original one-way security screws which can be installed using a standard flat-bladed screwdriver but cannot be easily removed.

Once installed these screws are almost impossible to remove without using the special one way screw removal tool or by drilling them out. Clutch head screws provide a high level of security at very low cost.

If you think that you may want to remove them again at some future date, consider using a two way sceurity screw instead such as one of our Security Torx range.
