Meet the Malco Zip-In 7X1/2 Self-Piercing Screws—a purpose-built fastener designed for fast, dependable sheet metal assembly. With a zinc-plated finish and a 1/4" hex washer head, these screws deliver clean penetration, strong clamping, and long-lasting durability in a single, efficient package.

Why Zip-In stands apart

  • Innovative two-thread design: A single starting thread runs all the way to the tip to initiate penetration, then a second thread above the point engages after entry to drive the screw in twice as fast. The result is quicker installations and more reliable holds, even in thicker gauges.
  • Heat-treated precision point: The advanced heat-treat process tapers the point to a razor-like tip without sacrificing strength, reducing wandering and maximizing first-pass drive power.
  • Heavy-gauge capability: Engineered to fasten heavier sheet metal more securely than typical self-piercing screws, giving you confident performance on demanding assemblies.
  • Corrosion-resistant finish: Zinc plating guards against rust in a variety of environments, helping your joints stay tight and looking good over time.
  • Solid, flush seating: The 1/4" slotted hex washer head distributes clamping force evenly and creates a clean, flush surface for trim and panels.
  • Convenient 100-count pack: Ready-to-use quantity for larger projects, reducing downtime and the need for frequent reordering.

Perfect for your sheet metal projects

  • Metal roofing, trim, and flashing installations where you want rapid penetration and strong holds without pre-drilling.
  • HVAC ductwork, metal enclosures, and other applications that demand dependable fastening in heavier-gauge metal.
  • Automotive body work and workshop projects that benefit from a fast, durable self-piercing solution.

How these screws solve common problems

  • Eliminates the need for pilot holes in many sheet metal applications, speeding up builds and reducing labor.
  • Less risk of cam-out and strip-outs thanks to the optimized head design and precise drive compatibility.
  • Consistent performance across varied metal thicknesses, thanks to the dual-thread approach and robust tip.

Practical tips for best results

  • When working with very thick gauges, ensure surfaces are clean and free of burrs to maximize bite and reduce deformation.
  • Use a proper hex driver to maximize torque transfer and prevent stripping of the washer head.
  • Align sheets carefully and support the material to minimize deflection during fastening for a crisper, tighter joint.

Choose the Malco Zip-In HW7X1/2ZG screws for a fast, reliable, and durable self-piercing fastening solution that handles heavier sheet metal with ease. A practical, high-performance option for professionals and serious DIY enthusiasts seeking efficiency without compromising strength.
