Did you know?
The Clutch Head Screw was probably the world’s first security type fastener to be mass produced!
Security Screws are simply a variation on our normal types of screws but with a tamper-proof head. They are also sometimes known as Anti-Theft Screws.
Whilst the body of the screw looks identical to a normal screw, the head has a pattern that cannot be undone with a slotted, Phillips or pozidrive screwdriver or bit.
Why use Self-Tapping Screws?
Self-Tapping Screws usually referred to as Self-Tappers, are screws for use when fastening to metal or plastic. The main difference with Self-Tappers is that they eliminate the need for pre-drilling a hole as a separate operation.
All that is required to insert a Self-Tapper is a pilot or punched hole to introduce the screw. They then form their own thread as the screw is driven into position. Once inserted, Self-Tapping Screws may be removed and re-used.
Security Screws are generally used to deter removal (often for safety purposes) or to prevent theft. They are commonly found in public conveniences, schools, prisons; on cars, boats, public transport; and in electrical items.
