Meet Malco Zip-In 8x2 Self-Piercing Screws — the fast, precise solution for sheet metal assemblies. Built to pierce cleanly and hold securely, these zinc-plated fasteners deliver consistent performance when you’re installing panels, flashing, or enclosures without the need for pre-drilling.
Why Zip-In stands apart
- Innovative thread architecture: A single starting thread runs all the way to the tip to initiate penetration with minimal resistance, while a second thread above the point engages after initial entry. This dual-thread action creates a “double fast” effect, driving the screw deeper and stabilizing the bite right away.
- Heat-treated for strength and penetration: Our specialized heat-treat process tapers the point to a fine, sharp tip without sacrificing critical point strength, so you get a confident, fast start every time.
- Fast, efficient driving: The optimized thread geometry reduces drive time and improves capacity for heavier gauge sheet metal compared with other self-piercing screws.
- Durable, corrosion-resistant finish: Zinc-plated coating protects exposed fasteners in challenging environments, helping your installations endure the elements.
- Robust package for professionals: 1400-count supply ensures you can complete large projects without constant reordering.
- 1/4" slotted hex washer head: Provides a secure seating with common drivers and a flush finish for a neat, professional look.
Ideal applications and use cases
- HVAC ductwork and metal enclosures where quick, reliable fastening through thicker sheet metal is essential.
- Metal roofing and flashing installs that benefit from fast penetration and strong clamping power.
- Fabrication and repair of equipment housings, panels, and other sheet-metal assemblies where pre-drilling is impractical or time-consuming.
How to use
- Align the workpieces and begin driving with a compatible driver bit
- Let the screw’s initial thread bite through the metal, then the second thread engages to complete the fastening
- Apply steady pressure and avoid over-tightening to prevent dimpling or damage to thin panels
Practical tips for best results
- For typical sheet-metal thicknesses, let the Zip-In screw do the work without pre-drilling; for very thick or reinforced assemblies, consider pilot guidance as needed.
- Keep the driving tool steady and aligned to prevent cross-threading or wobble that can reduce holding power.
- Store in a dry place to preserve the zinc finish and extend service life in field installations.
When you need a fast, dependable self-piercing solution for sheet metal, the Malco Zip-In 8x2 Self-Piercing Screws deliver penetrating power, secure clamping, and a finish that stands up to real-world use — making quick work of metal-to-metal assemblies across HVAC, roofing, and equipment enclosures.
