Fasteners Plus ST Fastening Kwikseal Woodbinder #10 x 1-1/2 in Tan

In this review the Fasteners Plus ST Fastening Kwikseal Woodbinder #10 x 1-1/2 in tan screws are evaluated for contractors and DIYers who attach metal roofing or siding to wood. The bottom line: these screws are built for durability and a reliable weather seal, and the single biggest reason to buy is the vulcanized EPDM rubber washer that maintains a watertight seal even when driven at an angle. The review focuses on real-world performance, coating longevity, and whether the screw design simplifies installation on post-frame and residential projects.

Key Features

• Coated Screws: A 2.5 mil powder coating with a UV inhibitor resists chalking and fading to keep fasteners looking consistent on exterior panels.
• KS V-Neck Head Design: The hex washer head with V-neck adds strength during high torque driving, reducing the chance of head twist-off on tough installs.
• EPDM Rubber Washer: The rubber is vulcanized to a steel washer to form a reliable seal that prevents leaks, even when the screw is entered at an angle.
• KS Lo-Root Thread: The thread profile transitions from fine to coarse to improve pullout strength in wood compared with traditional thread forms.
• Micro-Bit Point: The point consistently penetrates metal panels to avoid the need to pre-punch or score the sheet before driving.

Who It's For

These screws are best for contractors, roofers, and serious DIYers working on metal roofing and siding attached to wood framing, particularly in post-frame buildings or residential metal roof projects where a long-lasting seal matters. The combination of a strong coated finish and a vulcanized washer makes them suitable for exposed panels where appearance and weather resistance are priorities.

Those looking for specialty lengths, different head styles, or fasteners for attaching metal to metal should look elsewhere; this product is specifically engineered for metal-to-wood applications where the EPDM washer and thread design are required.
