Self Tapping Screws - Hexagon

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.

Hexagon head self tappers (usually called hex head) have a six-sided head that requires a socket or spanner to fasten. You can also use a tool called a nut spinner or nut driver to fasten a hexagon head – this is effectively a screwdriver with a socket head instead of a blade or pozidrive end.

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.

Our hex head self tappers are all AB style. Type AB has a sharp point on the end (sometimes called a gimlet point) and is commonly used with brittle materials and thin sheet metals. Type AB is the most common type of self tapper for general use.
