#10 x 1-1/2ft Kwikseal Woodbinder Metal Roofing Screws - Forest Green

In this review the Fasteners Plus ST Fastening #10 x 1-1/2' Kwikseal Woodbinder screws are evaluated for roofing and siding installers who need coated, sealing fasteners that resist fading and provide reliable pullout strength. The bottom line: these screws are best for contractors or experienced DIYers installing metal panels to wood where a durable colored finish, strong head design and a leak-resistant washer are priorities. The review focuses on real-world performance details like coating durability, thread engagement and how well the micro-bit point starts into metal.

Key Features

• Durable powder coating: The 2.5 mils of computer-controlled powder coating includes a UV inhibitor so the colored finish resists chalking and fading on exposed roofs and walls.
• V-neck hex head: The HWH V-neck head design adds strength and reduces the chance of head twist off when driving at high torque.
• EPDM rubber washer: The vulcanized EPDM on a G-90 steel backed washer provides a reliable seal that helps prevent leaks even when screws are installed at an angle.
• Lo-root thread: The KS Lo-root thread transitions from fine to coarse for better pullout strength in wood compared with traditional thread forms.
• Micro-bit point: The point consistently penetrates metal panels so installers rarely need to pre-punch holes, saving time on sheet installation.

Who It's For

These screws suit professional roofers, siding contractors and skilled homeowners installing metal roofing or metal siding to wood framing who want a colored fastener that resists UV fading and offers strong sealing performance. The built-in washer and robust head design make them a sensible choice where long-term weather resistance matters.

Those who need stainless steel corrosion resistance or a different length or thread profile should look elsewhere, as this product is a coated carbon-steel woodbinder screw optimized for metal-to-wood installations rather than marine or specialty applications.

Pros & Cons

Pros

• Consistent coating with UV inhibitor keeps the forest green finish from chalking for exterior longevity.
• V-neck hex head reduces head failure under high torque, making installation more trouble-free.
• EPDM washer vulcanized to a G-90 backing provides strong sealing and reduces leaks, even on angled installs.
• Micro-bit point removes the need to pre-punch metal panels in most cases, speeding up work.

Cons

• As coated carbon-steel fasteners, they are not stainless and may not be ideal for highly corrosive coastal environments.
• Stocked in a fixed length; jobs requiring other lengths will need a different SKU.

Frequently Asked Questions

Do these screws require pre-drilling of metal panels?
The micro-bit point design consistently pierces metal panels, so pre-drilling is usually unnecessary unless working with very thick gauge metal.

Will the color fade over time?
The 2.5 mils powder coating includes a UV inhibitor and is computer-controlled to resist chalking and fading in typical exterior conditions.

Is the washer sealed to prevent leaks?
Yes, the EPDM rubber washer is vulcanized to a G-90 steel backing to provide maximum sealing and reduce leaks even when screws are driven at an angle.
