Product Description
Metal‑to‑metal stitch fasteners for roofing, siding, and panel lap connections
#1/4‑14 × 7/8" Galvalume lap screws are designed for metal‑to‑metal fastening, especially where two panels overlap. Their short length prevents over‑penetration, making them ideal for stitching thin‑gauge metal roofing and siding panels. The Galvalume coating provides excellent corrosion resistance, while the hex washer head ensures strong driver engagement. Most lap screws include an EPDM sealing washer, helping maintain a weather‑tight seal in exterior applications.
