Self Tapping Flange Head Pozi Screws Black

This 3.5mm diameter, 19mm length black self-tapping screw is designed for applications requiring greater penetration depth whilst maintaining a smaller diameter profile. The 19mm length makes it ideal for securing thicker materials or where fastening through multiple layers is required, perfect for attaching brackets, mounting hardware, and heavier duty sheet metal work. The flanged Pozi head provides an integrated washer effect that distributes fastening pressure across a wider surface area, preventing pull-through and material damage. The self-tapping design creates its own thread as you drive it home, eliminating time-consuming pre-drilling operations. Manufactured to BS 4174 specifications and supplied in a pack of 100 within a resealable bag for convenient storage and organisation.
