Security Self Tapping Screws

About our Self-Tapping Screws

Our Security Self-Tapping Screws all have a pin located in the middle of the drive to prevent removal with standard tools making them excellent tamper-proof screws. We stock a choice of Pin Hexagon or Pin Resistorx 6 lobe drive, and both are available in a stainless-steel finish.

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, or Self-Tapping Bolts. 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 differentiator of 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.

Why use Security Screws?

Security Screws are machine bolts that 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.

We stock a Security Bit Set that covers all the popular Security Screw head types.
