Self Tapping Flange Head Pozi Screws Black 4.2mm 19mm Pack of 100

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.
