  • Optimize your metal building projects with our #14 x 7/8" Stitch Lap ZXL Dome Cap Metal Building Screws, designed for metal-to-metal applications. These self-drilling screws are ideal for attaching metal roof and sidewall panels together, ensuring a secure and reliable hold. Key features include:

    • Self-Drilling 7/8" Stitch Lap Metal Building Screws: No need for pre-drilling. The self-drilling tip easily penetrates steel up to .210" thickness with no 'point-walking,' ensuring precise and effortless installation.
    • Secure Fastening: Stitch lap screws will securely fasten two layers of up to 18 gauge thickness with no strip-out, thanks to the tapered shaft that holds strong in the panel laps.
    • ZXL Dome Cap Head: The 5/16" ZXL Dome Cap head completely encapsulates the washer, preventing UV damage and ensuring the screws last for years longer than industry-standard screws.

    Multiple Colors

    • Available in 17 different color options to match your specific project. Each bag contains 250 screws.
    • Note: Actual screw color may differ due to varying monitor settings. We are happy to send a small sample for color matching. Please contact us to receive a color sample.

    Easy to Install

    • Designed for easy installation, suitable for anyone regardless of experience. Each order includes a free 5/16" Hex Driver.
    • Advanced forging process technology ensures sharp drill edges that consistently cut the metal, eliminating slow or dropped screws and preventing pigtails that can embed themselves in the rubber washer.

    All product prices include free Standard Shipping in the Lower 48 States.
