Introducing Malco HW8X1/2ZP Zip-In Self-Piercing Screws — a bulk, zinc-plated solution built for fast, confident metal fastening. This 8x1/2" sheet metal screw comes in a 7,000-count pack, designed for professionals who demand speed, reliability, and long‑lasting performance on large projects.
What makes Zip-In different
- Innovative thread geometry: a single starting thread forms down to the tip, delivering immediate penetrating power as you begin to drive the screw.
- Double-thread action: a second thread above the point engages after initial penetration, effectively drilling in twice as fast for quicker assemblies.
- Precision heat treatment: a sophisticated heat‑treat process tapers the point to a fine, sharp tip without sacrificing critical point strength, reducing cam-out and easing starting torque.
- Heavy-gauge performance: engineered to fasten heavier gauges of sheet metal more reliably than other self‑piercing screws, expanding the range of compatible materials.
- Corrosion-resistant finish: zinc plating protects against rust, making these screws suitable for varied environments and long-term assemblies.
- Secure seating with a clean finish: the 1/4" slotted hex washer head provides a dependable drive and a flush, professional look.
- Bulk efficiency: 7,000 screws per pack means fewer reorders on big jobs and in busy shops, keeping projects moving.
Ideal applications include metal roofing and siding installations, HVAC ductwork, enclosures, and other sheet-metal projects where speed and reliability matter. With Zip-In, you get faster driving and stronger joints, even when working with thicker metal — all in a dependable, bulk-pack solution from Malco.
