Self Tapping Screws - Slotted Countersunk - Type B - BZP

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.

Pozidrive countersunk head self tappers are used when a flush finish is required, with no part of the screw head protruding above the level of the item being fastened.

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.

A BZP or bright zinc plated fastener is one which has a thin coating of zinc added during production. This protective coating adds durability by protecting the product against rust or oxidisation.
