MPN: HW8X1Z
Minimum order quantity is .
Meet Malco HW8X1Z Zip-In Self-Piercing Screws, the fast, reliable solution for joining thin to medium sheet metal with precision. Built around Zip-In’s signature threading and heat-treated metallurgy, these screws are designed to pierce metal cleanly and hold securely in place from the first bite to the final drive.
Why Zip-In stands apart
- Dual-thread piercing power: A single starting thread forms all the way to the tip to initiate penetration, followed by a second thread above the point that engages after initial entry, delivering double-fast drilling and strong, continuous thread engagement.
- Optimized heat treatment: The advanced heat treat process tapers to a fine, sharp point without compromising critical point strength, ensuring consistent performance across every screw.
- Efficient, fast driving: Designed to drive quickly through sheet metal, reducing installation time on big projects and minimizing operator fatigue.
- Heavy-gauge capability: Specifically engineered to fasten heavier gauges of sheet metal more effectively than standard self-piercing screws.
- Corrosion resistance: Zinc-plated finish provides durable protection in everyday shop or field environments.
Packaged as a bulk 7000-count supply, the Malco Zip-In screws are ideal when you’re outfitting a shop, fleet, or job site with a dependable, long-lasting fastener that reduces pre-drilling and speeds assembly.
Key specifications in context
- Size and head: 8X1 self-piercing screws with a 1/4" slotted hex washer head
- Finish: Zinc plated for corrosion resistance
- Quantity: 7000-count pack for bulk projects
Ideal applications
- Automotive body panels and enclosures where quick, secure metal-to-metal fastening is needed
- HVAC ductwork, metal roofing, and siding installations
- Electrical enclosures, control boxes, and equipment housings
- Fabrication of metal cabinets, panels, and lightweight structural assemblies
How this screw solves real-world problems
Traditional self-piercing screws can struggle with heavier metal gauges or require pre-drilling, slowing down production. Zip-In’s dual-thread design, combined with a sharpened point and robust heat treatment, delivers rapid penetration and dependable thread engagement right away. The result is fewer reworks, fewer skipped holes, and a cleaner, more consistent fastener performance across the job site.
Practical tips for best results
- Use a compatible driver for the 1/4" slotted hex washer head to ensure full seating and minimize cam-out.
- Align the screw with the sheet metal surface and apply steady, even pressure to maximize penetrating power.
- When joining multiple panels, consider a staggered pattern to distribute load and reduce the chance of binding.
- Plan for bulk deployments with the 7000-count pack to keep projects moving without interruptions.
Choose Malco Zip-In Self-Piercing Screws for a cutting-edge combination of speed, strength, and reliability in sheet metal assemblies. The HW8X1Z provides the right balance of piercing power and heavy-gauge capability to tackle demanding metalwork with confidence.
