These Malco Zip-In® self-piercing screws are designed for efficient fastening in HVAC metal ductwork. Their unique double thread design, combined with a sophisticated heat treatment process, results in a sharp, durable point for instant penetration and faster driving compared to standard self-piercing types, even in heavier gauge sheet metal. The quality-controlled manufacturing ensures consistent performance.The undercut hex washer head is designed to seat flush, and the full 1/4" head size helps prevent stripping in the hex driver opening. These case hardened steel screws are zinc-plated for corrosion resistance.
