#10 x 1-1/2ft Kwikseal Woodbinder Metal Roofing Screws - Pack of 250

In this review the Fasteners Plus ST Fastening #10 x 1-1/2' Kwikseal Woodbinder screws are judged as a practical choice for contractors and DIYers who install metal roofing or metal siding onto wood. The bottom line: these screws deliver consistent penetration and a dependable seal, so the biggest reason to buy is reliable leak prevention and strong pullout resistance on wood substrates. The reviewer found them straightforward to use and particularly suited when color-matched coated heads and durable washers matter on exposed metal panels.

Key Features

• Coated finish: The 2.5 mils of computer controlled powder coating resists chalking and fading so panels stay visually consistent over time.
• V-neck hex head: The head design increases strength under high torque and helps prevent the head from twisting off during fast driving.
• EPDM rubber washer: Vulcanized to a G-90 steel backed washer to form a durable seal that prevents leaks even when screws are installed at an angle.
• Lo-root thread: The thread transition from fine to coarse provides improved pullout strength in wood compared with traditional thread forms.
• Micro-bit point: The point consistently penetrates metal panels so the installer rarely needs to pre-punch holes before driving.

Who It's For

These screws are best for contractors, siding installers and experienced DIYers working with metal roofing or metal siding mounted to wood purlins or sheathing. The combination of coating and vulcanized EPDM washers makes them suitable for visible exterior applications where both appearance and watertightness matter.

Those who need stainless steel fasteners for corrosive coastal environments or very long-term marine exposure should look elsewhere; this product is a coated steel screw designed for typical residential and light commercial roofing, not a marine-grade alloy fastener.

Pros & Cons

Pros

• Consistent coated finish that resists UV fading and keeps fasteners matching colored panels.
• Head and thread design reduce head failure and improve pullout strength in wood.
• EPDM washer vulcanized to steel provides a reliable seal that tolerates angled installation.
• Micro-bit point makes driving through metal panels fast and reduces the need to pre-punch holes.

Cons

• Coated steel is not a substitute for stainless fasteners in harsh saltwater environments.
• Pack size and head color limit may be more than needed for very small projects.

Frequently Asked Questions

Are these screws suitable for metal-to-wood applications?
Yes. The thread form, micro-bit point and washer are designed specifically for securing metal panels to wood substrates.

Will the EPDM washer prevent leaks if screws are installed at an angle?
Yes. The EPDM rubber is vulcanized to a steel backing to maintain sealing ability even when driven at an angle.

Are these stainless steel screws?
No. These are coated steel fasteners with a powder coating and are not intended as a substitute for stainless fasteners in highly corrosive environments.
