Malco 8X1 White Zip-In Self-Piercing Screws — 1/4" Slotted Hex Washer Head, Zinc Plated, 500 Count — a color-matched fastening solution designed for gutters, trim coil, and painted sheet metal projects. This is the Malco HW8X1ZWT family, built for fast, reliable installation outdoors where appearance matters as much as strength.

Designed to blend with common gutter and trim coil colors, these painted sheet metal screws reduce visible fasteners while delivering dependable hold. The 1/4" slotted hex washer head seats cleanly and works with standard drivers, making installation straightforward even for DIY projects or professional jobs.

Key features that matter in the field

• Self-piercing action: No separate pilot hole needed in typical light to medium-gauge metal. The screw creates its own path as you drive, speeding up installations on gutters, trim, and metal panels.
• Color-matched white finish: Specifically formulated to harmonize with gutter and trim coil palettes, yielding a cohesive, professional look on finished work.
• 1/4" slotted hex washer head: Provides secure seating and compatibility with common drivers for stable driving without slipping.
• Zinc-plated for outdoor durability: Enhances corrosion resistance to stand up to weather, moisture, and temperature fluctuations.
• 8X1 size: Sized for typical gutter and trim applications, offering a balanced bite without excessive penetration.
• 500‑count bulk package: Keeps you stocked for large jobs or ongoing projects, reducing downtime and trips to the supplier.

Ideal uses and practical benefits

• Gutter installations on aluminum or steel systems where a clean, color-coordinated finish is essential.
• Attaching trim coil to fascia, soffits, or metal siding where a concealed-fastener aesthetic matters.
• Weather-exposed metal projects that benefit from reliable self-piercing performance and durable zinc protection.

Tips for best results

• Prepare the surface by removing dust and oils; a clean base helps the finish stay true and the fastener seat flush.
• Start at a corner or end of a run to maintain a straight line and even spacing across sections.
• Use the appropriate driver to avoid cam-out and ensure the hex washer head sits snugly without over-penetrating.
• If color-matching is critical, test a single screw in a hidden area before committing to the entire installation.

Whether you’re upgrading gutters, refreshing trim coils, or completing painted metal assemblies, Malco’s white, self-piercing screws offer a practical, color-coordinated fastening solution built to perform under real-world conditions. Durable, easy to install, and available in ample quantities, they’re designed to help you finish projects with a clean look and lasting hold.
