Fasteners Plus ST Fastening ZXL #14 x 1-1/2 in Charcoal Screws

In this review the Fasteners Plus ST Fastening ZXL #14 x 1-1/2 in charcoal screws are evaluated for contractors and DIYers who need reliable metal-to-wood fastening for roofing and siding. The single biggest reason to buy is their corrosion-resistant ZXL no red rust hex head and cup washer design that protects the head and sealing washer over a long service life, making them ideal for metal roofing and siding retrofit or new-install applications where longevity and a dependable seal matter.

Key Features

• Type AB point: The self-tapping Type AB point cuts threads into wood and sheet metal quickly, reducing pre-drilling time on roof and siding panels.
• ZXL no red rust hex head: A molded ZAMAC zinc-aluminum cup head provides manufacturer lifetime protection against red rust on the head and washer, improving long-term appearance and corrosion resistance.
• Installation type: #14 carbon steel fasteners are sized for attaching steel roofing and siding to wood framing in post-frame and residential projects, providing a strong metal-to-wood connection.
• Rescue screw use: The larger diameter makes these suitable for retrofit work where stripped or backed-out screws need replacement with a more secure fastener.
• EPDM washer: The cupped head holds the EPDM washer in place even when driven at an angle, which maximizes pull-over strength and improves the water seal around the fastener.

Who It's For

These screws are best for builders, roofing contractors, and experienced homeowners who install or repair metal roofing and siding on barn, pole, and post-frame structures or wood-framed buildings. The combination of a #14 carbon steel shank, Type AB point, and EPDM washer suits applications where a reliable seal and easy self-tapping performance speed installation.

Less suitable users include those who require stainless steel fasteners for marine environments or projects needing non-coated heads for paint-matching; color match reports are mixed, so painting or touch-up may be necessary for visible panels where an exact match is critical.

Pros & Cons

Pros

• Durable corrosion protection on the head and washer thanks to the ZXL molded ZAMAC cup head, improving long-term rust resistance.
• Strong sealing performance because the EPDM washer is captured by the head and resists displacement when driven at an angle.
• Good value for money; customers note these are less expensive than alternatives while maintaining expected functionality.
• Rescue screw capability allows reuse in retrofit situations where existing fasteners are stripped or backed out.

Cons

• Color match has mixed feedback, so the charcoal finish may not perfectly match all panels without touch-up.
• Made from carbon steel with a coated head rather than stainless steel, so extreme marine or highly corrosive environments may require a different material choice.
