GVAKMM 300Pcs #10 x 1-3/8" Zinc Metal Roofing Screws, Hex Colored Head Self-Drilling Metal to Wood Siding Fasteners, in Reusable Storage Case, Hex Driver Bit Included

PRECISE DIMENSIONS FOR SECURE FIT – Designed with a standard 5/16" (8mm) Hex Head and a generous 0.54" diameter EPDM washer for maximum coverage. The #10 screw features a 1-3/8" (35mm) length, making it the ideal size for fastening metal roof panels to wood battens or plywood without excessive protrusion.

LEAK-PROOF EPDM SEALING – Our screws utilize a premium 0.105" thick EPDM rubber washer，This conductive-resistant material compresses tightly upon installation to create a watertight seal, effectively preventing leaks and protecting the screw hole from moisture intrusion even in harsh weather.

METAL-TO-WOOD APPLICATION – Engineered specifically for attaching thin-gauge metal sheeting to wood structures. The Type-17 self-drilling point pierces metal surfaces quickly while the coarse thread grabs into wood framing securely. Note: Not recommended for thick steel beams

TESTED CORROSION RESISTANCE – Coated with a durable protective finish capable of passing 1,000-hour salt spray testing. The screw heads are painted to match standard RAL roofing colors (RAL 9006), blending seamlessly with your panels while resisting chalking and fading from UV exposure.

STURDY REUSABLE STORAGE CASE – Forget flimsy paper boxes that tear and spill. Our 300pcs roofing screws come neatly organized in a heavy-duty, transparent plastic storage case. This durable packaging ensures your screws stay secure during transit and provides a convenient way to organize your workshop or job site. Includes a free 5/16" magnetic hex driver bit inside for immediate use.
