Sealey Self Tapping Flange Head Pozi Screws Black

This 4.2mm diameter, 19mm length black self-tapping screw is engineered for demanding applications requiring both strength and penetration depth. The 19mm length makes it ideal for fastening through thicker materials, multiple layers, or where longer thread engagement is necessary for maximum holding power in sheet metal fabrication, automotive repair, and industrial maintenance. Featuring a flanged Pozi head that provides an integrated washer effect, this screw distributes fastening forces evenly to prevent surface damage and pull-through. The self-tapping design creates its own thread during installation, eliminating the need for pre-drilling and accelerating your work rate. Manufactured to BS 4174 British Standard specifications, supplied in a pack of 100 within a convenient resealable bag.
