Meet Malco Zip-In HW8X1/2ZG — a self-piercing screw crafted to transform sheet metal fastening. Designed for speed, reliability, and strong holds, these screws pierce cleanly without pre-drilling and then bite in twice as fast, delivering a secure connection with less effort.
- Innovative thread geometry: a single starting thread runs right to the tip to deliver immediate piercing power, while a second thread above the point engages after initial penetration for a double-fast drive.
- Precisely heat-treated point: the advanced heat treat process keeps the tip sharp and strong, ensuring consistent penetration even into heavier gauge sheet metal.
- Faster, cleaner installations: optimized for quick driving, reducing installation time and minimizing driver fatigue on long runs.
- Heavy-gauge capability: engineered to fasten thicker sheet metal more reliably than traditional self-piercing screws, reducing the need to switch to alternative fasteners mid-project.
- Dependable finish: zinc-plated coating provides corrosion resistance for long-term performance in a variety of environments.
- Practical head design: 1/4" slotted hex washer head combines versatility with a secure, flush seating profile that helps prevent pull-out and cam-out.
- Convenient packaging: comes in a 100-count bundle, ready for larger jobs or ongoing use on multiple projects.
What problems does this solve? When you’re fastening metal to metal or metal to thin-gauge panels, pre-drilling can slow you down and compromise accuracy. Zip-In screws eliminate the extra step, provide immediate bite, and maintain strong holding power as you work through heavier gauges. The result is faster assemblies, fewer reworks, and a cleaner finished look.
Ideal for: HVAC ductwork, metal roofing and trim, appliance enclosures, automotive body panels, and any project requiring quick, dependable sheet-metal fastening without pre-drilling.
Why choose Zip-In over other self-piercing options? The unique two-thread system and heat-treated point deliver rapid penetration and robust clamping force, even when dealing with thicker metal. The zinc finish adds resilience against corrosion, while the slotted hex washer head ensures a snug, flush fit that stays in place under vibration or outdoor exposure.
