Long Life Durability for Roofing and Siding Applications – Engineered to outlast standard lap stitch screws, these corrosion-resistant fasteners maintain their color, finish, and strength through UV exposure, moisture, and temperature extremes. The Polar White coating provides a clean, consistent appearance for years of outdoor use.
Self-Tapping Design for Fast, Reliable Installation – The sharp self-tapping point drives easily through overlapping metal panels and siding joints without predrilling. Balanced threads ensure smooth starts, tight seating, and secure fastening—ideal for laps, ridge caps, and trim applications.
5/16" Hex Head for Confident Torque Transfer – The reinforced 5/16-inch hex head provides steady torque delivery and reliable bit engagement, minimizing driver wear and slippage. Hardened carbon steel construction ensures strength and precision during every install.
EPDM Sealing Washer for Long-Term Weatherproofing – Each fastener includes a UV-stable EPDM washer that compresses evenly beneath the head to form a watertight seal. The flexible rubber barrier prevents leaks, corrosion, and staining while retaining elasticity through seasonal temperature swings.
250-Piece Contractor Pack for Professional Use – Packaged in a 250-piece bag, these #14 × 7/8 lap stitch screws deliver consistent, corrosion-resistant fastening for roofing overlaps, siding joints, and trim connections. Ideal for contractors seeking reliable strength, lasting quality, and color coordination.
