ZXL Tapping Woodbinder #14 x 1-1/2 in Screws - Metal-to-Wood Roofing

In this review the ZXL Tapping Woodbinder #14 x 1-1/2 in screws are evaluated for homeowners, contractors, and post-frame builders who need dependable metal-to-wood fasteners for roofing and siding. The bottom line: these screws are a practical choice for retrofits and new installs because their self-tapping Type AB point and molded ZAMAC head simplify installation while the vulcanized EPDM washer delivers a reliable weather seal. For anyone replacing stripped screws or fastening long-life metal panels to wood, the product balances durability, ease of use, and value.

Key Features

• Type AB point: The self-tapping tip cuts threads into wood quickly, removing the need for pre-drilling in most installations and saving time on the roof.
• ZXL no red rust hex head: The 5/16 in cupped hex washer head molded from a ZAMAC zinc-aluminum alloy resists red rust on the head and washer for long-term appearance and performance.
• #14 carbon steel fastener: The larger diameter provides extra holding power and is suitable for attaching steel roofing and siding to wood framing in residential and post-frame buildings.
• Rescue screw capability: The larger size makes these effective for retrofit jobs where existing screws have been stripped or backed out and require a secure replacement.
• EPDM rubber washer: The vulcanized EPDM to steel washer maintains a watertight seal even when screws are driven at an angle, maximizing pull-over strength and weather protection.
• Powder coating: Colored coatings include UV inhibitors and a 2.5 mil finish that resists chalking and fading for longer-lasting color retention on exposed panels.

Who It's For

These screws are aimed at contractors, DIY homeowners, and building owners working on metal roofing and siding who need a dependable metal-to-wood fastener that installs quickly and resists head corrosion. They are especially useful in retrofit situations where stripped fasteners must be replaced with a larger diameter that re-engages the substrate.

They are not intended for direct installation into concrete, masonry, or thin-gauge metal without appropriate backing; users needing stainless steel corrosion resistance in marine environments should consider alternative materials.

Pros & Cons

Pros

• Excellent holding power from the #14 carbon steel design, giving confidence for heavy paneling.
• The molded ZAMAC head and EPDM washer provide long-term protection against red rust and a secure weather seal.
• Self-tapping Type AB point speeds up installation by usually eliminating pre-drilling.
• Cost-effective option noted by customers as good value for money compared with pricier alternatives.

Cons

• Color match has received mixed feedback, so painted finishes may not perfectly match every panel color.
• Not stainless steel, so extreme coastal corrosion environments may require a different fastener choice.

Frequently Asked Questions

Can these screws be used to replace stripped fasteners?
Yes, the larger #14 diameter is intended for rescue or retrofit applications where existing screws have been stripped or backed out and a larger screw is needed.

Do the washers provide a reliable weather seal?
The EPDM washer is vulcanized to the steel washer and is designed to maintain a watertight seal even when driven at an angle, improving pull-over strength and weather protection.

Are these screws suitable for coastal locations?
They feature a ZAMAC coated head for red rust protection, but they are carbon steel fasteners; for prolonged coastal exposure, a stainless option may be preferable.
