#10 x 1 Kwikseal Woodbinder Metal Roofing Screws Pack of 250 - Durable

In this review the Fasteners Plus #10 x 1 Kwikseal Woodbinder screws are judged for contractors and DIYers who install metal roofing or siding and need reliable, weatherproof fasteners. The bottom line: these coated, micro-bit point screws deliver consistent penetration and strong holding power, and the vulcanized EPDM washer provides a dependable seal, making them a practical choice when longevity and leak prevention matter most.

Key Features

• Coated finish: 2.5 mils of computer controlled powder coating resists chalking and fading, so the visible heads maintain color over time and under UV exposure.
• V-neck head design: Hex washer head with a V-neck shape adds strength and helps prevent head twist-off when using high torque drivers on metal panels.
• EPDM rubber washer: Vulcanized to a G-90 steel backed washer for a watertight seal that tolerates angled installation without letting water through.
• Lo-root thread: Thread transitions from fine to coarse for improved pullout strength compared with traditional thread forms, helping keep panels secured to wood substrates.
• Micro-bit point: Sharp point consistently drills through metal panels, eliminating the need to punch starter holes and speeding installation.

Who It's For

These screws are aimed at roofing contractors, metal siding installers, and experienced homeowners installing metal panels to wood framing who require a durable fastener that seals against weather. The combination of a strong head, lo-root thread and vulcanized EPDM washer suits jobs where long-term holding and leak prevention are priorities.

Those who primarily fasten into steel substrates or who need specialty lengths or self-drilling into thick structural steel should look elsewhere, as these are designed to fasten metal panels to wood and are optimized for that use case.

Pros & Cons

Pros

• Reliable corrosion-resistant powder coating helps maintain appearance and protects the head from UV degradation.
• V-neck HWH reduces the risk of head failure under heavy torque, useful with impact drivers.
• Vulcanized EPDM washer and steel backing give a solid seal that performs even when screws are driven at an angle.
• Micro-bit point speeds installation by penetrating metal panels without pre-punching.

Cons

• Pack contains screws sized for wood attachment; it is not a universal solution for attaching to thick steel or concrete without different fastener types.
• Color-matched heads reduce visibility but customers should confirm a perfect color match for visible projects.
