Security Self Tapping Screws - Pin Hex Button Head

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.
