Minimum order quantity is .
When fast, dependable sheet-metal fastening is non-negotiable, Malco Zip-In 8X3/4 Self-Piercing Screws (HW8X3/4Z) are built to deliver. This zinc-plated, 1/4" slotted hex washer head screw is designed for quick, confident piercing through heavier gauge metals—so you spend less time driving and more time building.
What sets Zip-In apart is a precision-engineered thread profile and a smart heat-treat process that markers the difference between “almost there” and “done.” A single starting thread runs all the way to the tip, providing immediate piercing power. As soon as the point begins to enter the metal, a second thread above the tip engages, drilling in quickly and securing the fastener with less effort. The result is faster driving, cleaner starts, and a stronger hold in demanding metal assemblies.
- Innovative thread design: Start-to-tip thread that powers entry, plus a second thread that drives the screw home after initial penetration.
- Heat-treated for strength: A refined point that stays sharp and strong, ensuring reliable performance through thicker sheet metal.
- Heavy-gauge capability: Specifically engineered to fasten heavier gauges of sheet metal more efficiently than typical self-piercing screws.
- Durable zinc finish: Zinc-plated coating protects against corrosion in challenging environments, extending service life.
