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

In this review the focus is on a pack of #10 x 1-1/2' ZXL Woodbinder metal-to-wood roofing screws intended for contractors and serious DIYers who need corrosion resistance and reliable fastening for metal roof panels. The bottom line: these screws stand out for their robust ZAMAC molded head with an encapsulated EPDM washer and a 2.5 mil powder coat over zinc plating that resists UV and chemical breakdown, making them a strong choice when longevity and weather resistance matter most.

Key Features

• Coated finish: A 2.5 mil computer-controlled powder coat over zinc plating and chromate sealer provides extended UV and chemical resistance for longer life outdoors.
• ZXL molded head: The 5/16' cupped hex washer head is molded from a zinc-aluminum alloy that encapsulates the EPDM washer for a durable, leak-resistant seal.
• KS lo-root thread design: Thread geometry transitions from fine to coarse to deliver improved pullout strength compared with traditional thread forms.
• Micro-Bit point: The MB drill point consistently penetrates metal panels without pre-punching, useful for ridge caps and trim where multiple thicknesses occur.
• Environmental profile: The powder coating contains no volatile organic compounds and is fully recyclable, reducing harmful emissions during manufacture.

Who It's For

These screws are aimed at roofing professionals and experienced homeowners installing metal panels over wood substrates who need a weatherproof fastener that resists rust and holds tightly over time. The molded head and EPDM washer combination makes them well suited to metal-to-wood applications where water shedding and seal integrity are priorities.

They are less appropriate for casual, infrequent use where cost sensitivity is paramount; customers who prioritize the lowest possible price or need a different head style should consider other fasteners.

Pros & Cons

Pros
