Fasteners Plus Kwikseal Woodbinder #10 x 2 Burnished Slate Screws

In this review the Fasteners Plus ST Fastening Kwikseal Woodbinder screws are judged for contractors and DIYers who attach metal roofing or siding to wood structures; the single biggest reason to buy is the reliable seal and pullout strength they provide, which reduces callbacks for leaks or loose panels. The reviewer tested the screws on steel roofing panels and wood purlins and found the combination of the EPDM rubber washer and powder coating delivers lasting weather resistance while the micro-bit point design makes starting and driving faster than generic wood screws.

Key Features

• Coated screws: The 2.5 mils of computer controlled powder coating resists chalking and fading so the finish holds up under sun exposure.
• KS V-neck head design: The hex washer head with V-neck adds strength to prevent head twist off when using high torque drivers.
• EPDM rubber washer: The vulcanized EPDM on a G-90 steel washer maintains a waterproof seal even when screws are driven at an angle.
• KS lo-root thread design: The thread transitions from fine to coarse to provide better pullout strength in wood than traditional thread forms.
• Micro-bit point: The self-drilling point consistently penetrates metal panels so there is no need to pre-punch holes.

Who It's For

The screws are best for builders, roofers, and homeowners fastening metal roofing or siding to wood framing in post-frame and residential metal roof applications; the seal and thread form make them well suited to long runs of lap seams and exposed metal panels where weather resistance matters. Contractors who need a consistent, fast installation benefit from the micro-bit point design that reduces startup time and prevents wandering on thin panels.

These are not aimed at masonry or concrete fastening, and customers seeking stainless steel corrosion resistance for marine or extreme salt environments should look for alternative fasteners rather than these coated steel screws.

Pros & Cons

Pros

• Durable powder coating with UV inhibitor helps maintain appearance and resists chalking.
• V-neck HWH reduces the chance of head twist-off under high torque during installation.
• EPDM-welded steel washer offers a strong seal that performs even when driven at an angle.
• Thread and point design deliver good pullout strength and easy penetration of metal panels.

Cons

• Made from coated steel rather than stainless, so users in extremely corrosive environments may prefer a different material.
