Self Tapping Flange Head Pozi Screws Black

This 4.8mm diameter, 25mm length black self-tapping screw represents the ultimate combination of strength and penetration depth within this range. Perfect for the most demanding heavy-duty applications, this size excels where maximum holding power through thick materials is required, including structural steel fabrication, heavy equipment mounting, and industrial construction where reliability is non-negotiable. The flanged Pozi head design incorporates an integrated washer effect that distributes fastening pressure across a wider surface area, preventing pull-through and surface damage whilst maintaining superior retention under substantial loading. Self-tapping technology means the screw cuts its own thread as you drive it, removing the need for pre-drilling and streamlining installation. Manufactured to BS 4174 specifications and supplied in a pack of 100 within a resealable bag.
