Malco 8X11/2 Zip-In Self-Piercing Screws | 1/4" Slotted Hex Washer Head Sheet Metal Screws | Fast & Easy Piercing | Zinc Plated (4500 Count)
MPN: HW8X11/2Z
Minimum order quantity is .
Designed for rapid, reliable metal fastening, Malco Zip-In 8 x 1-1/2 Self-Piercing Screws deliver piercing power with minimal effort. The zinc-plated finish resists rust, making them ideal for outdoor and humid environments, and the 4500-count pack keeps large projects moving without interruption. These screws are purpose-built for sheet metal work where speed and accuracy matter, from roofing and flashing to ductwork and metal siding.
- Penetrating power engineered into every thread: A single starting thread forms all the way to the tip, providing an immediate bite, while a second thread above the point engages after initial entry to drill in twice as fast.
- Heat-treated for a fine, durable point: Sophisticated heat treat allows a sharp point without compromising point strength, enabling cleaner holes and better performance on heavier gauge sheet metal.
- Faster driving, less effort: The dual-thread action and precision tapering reduce drive time and improve seating, so you finish projects sooner with steadier, more secure fastening.
- Reliable head and corrosion resistance: A 1/4-inch slotted hex washer head provides solid seating and a broad bearing surface, while zinc plating protects against rust in challenging environments.
- Versatile, heavy-gauge capability: Specifically designed to handle heavier gauges of sheet metal more effectively than other self-piercing screws, expanding your range of applications.
Ideal for professionals and serious DIYers working on HVAC ductwork, metal roofing, flashing, gutters, and siding projects, these Zip-In screws simplify installation where pre-drilling isn’t practical. They reduce project downtime, minimize material damage from misdrives, and deliver consistent results even when working with thicker metal panels.
Use cases include fastening thin to moderately thick sheet metal, securing flashing to metal roofs, joining ductwork components, or attaching metal panels where a clean, fast penetrating operation is essential. For best results, start with steady pressure, maintain alignment, and use a power driver at an appropriate speed to maximize the benefits of the Zip-In design.
