Meet the Malco 6x3/8 White Zip-In Self-Piercing Screws—the fast, reliable solution for sheet metal projects where quick, clean fastening matters. Designed for gutters, trim coil, and other light-metal installations, these screws combine a sturdy 1/4 in. slotted hex washer head with a self-piercing style that makes homes and projects go together with less effort.

• Self-piercing design: drives through metal without needing pre-drilled pilot holes, reducing installation time and handling.
• 1/4 in. slotted hex washer head: provides a secure seating surface and compatible drive for standard tools, ensuring consistent, flush mounting.
• Zinc-plated finish: durable corrosion resistance for outdoor gutters, trims, and exterior metalwork.
• Painted color option: available in finishes that match common gutter and trim coil colors; this variant delivers a clean white appearance that blends with light-colored metalwork.
• Value-packed assortment: 100-count package, ideal for larger gutter runs or multiple projects without constant reordering.

Why this matters: in gutter and trim coil applications, a fastener that aligns quickly, seats firmly, and resists weathering makes a tangible difference. The Malco 6x3/8 White Zip-In Self-Piercing Screws are purpose-built for metal-to-metal or metal-to-wood scenarios where a tight seal and durable finish are essential. The white finish isn’t just cosmetic—it helps reduce visible staining and maintains a cohesive exterior look over time.

Ideal use cases:

• Securing gutters, downspouts, and fascia where a painted, color-coordinated fastener is preferred.
• Attaching trim coil and flashing in exterior metalwork to create clean, weather-resistant joints.
• Light-to-medium gauge metal assemblies where quick installation and reliable grip matter.

Practical tips:

• Keep mating surfaces clean and dry for best bite and finish.
• Drive steadily to allow the self-piercing point to form a precise hole without deforming the surrounding material.
• Use in appropriate gauge metal to maximize holding power; consider pairing with gaskets or sealants where a water-tight joint is required.
• Store in a dry place to preserve the zinc finish and color coating for future jobs.
