Meet Malco HW6X3/8ZRB, the Royal Brown Zip-In Self-Piercing Screws designed for quick, clean metal fastening on gutters, trim coils, and other sheet metal applications. With a 1/4" slotted hex washer head and a zinc-plated finish, these screws blend reliability with durability for outdoor use.

Color-matched performance for a seamless finish

These painted sheet metal screws come in a range of colors to closely match common gutter and trim coil finishes, so fasteners disappear against metal surfaces rather than stand out. The Royal Brown option is specifically tailored to blend with popular exterior color palettes, reducing visual disruption on installations where appearance matters as much as strength.

Fast, hassle-free installation

• Self-piercing (zip-in) design: Drives through metal cleanly without pre-drilling, saving time on each connection.
• 1/4" slotted hex washer head: Provides a secure, wide-bearing surface and compatibility with standard drivers for consistent seating.
• Zinc-plated corrosion resistance: Built to withstand outdoor conditions, helping maintain grip and appearance over the long term.

Ideal use cases

• Gutter installation and fastener replacement where color coordination matters
• Trim coil mounting and flashing on metal facades
• General sheet metal fastening projects requiring a robust, color-matched screw
