These 10 x 1-1/2″ charcoal hex head screws provide a strong fastening option for metal roofing and wood siding. The 1/2″ EPDM washer creates a dependable seal against leaks, while the head is painted to closely match charcoal roofing colors. The shaft diameter of .19″ and a total length including head measures 1-1/2″. While color matching may vary slightly between batches, the two-part polyurethane coating on the colored head offers enhanced durability over time.

Charcoal Hex Head Roofing Screws, 1″ Length

Fasteners Plus offers a 250-piece pack with a #12 x 3/4″ length, designed for metal roofing and siding. The screws feature a two-and-a-half mils powder-coated finish that resists chalking and fading, owing to UV inhibitors in the coating. The HWH with a V-neck head design adds strength to prevent head twist-off under torque, and the EPDM washer vulcanized to a G-90 steel backing ensures a strong seal, even at an angle. This combination supports durable installations in challenging weather conditions.

Maxx Steelbinder #14 x 7/8″ Charcoal Gray

This 7/8″ length screw from Fasteners Plus uses a self-drilling design suited for metal roofing panels in post-frame and residential structures. The 2.5 mils powder-coated finish resists UV exposure and chemical degradation, maintaining color integrity without chalking. The cupped head encapsulates the EPDM washer to deliver a reliable seal, even when driven at an angle. The ZAMAC-coated head provides corrosion resistance, extending the life of the fastener in harsh environments.

ZXL Woodbinder #10 x 1-1/2″ Charcoal Gray

Check Price on Amazon

This 1-1/2″ length ZXL Woodbinder features a zinc-aluminum alloy hex head with no red rust, ensuring longevity in outdoor metal roofing applications. The EPDM rubber washer is molded into the head, helping seal against leaks when driven at angles. The coating resists UV rays and chemical breakdown, and the product is designed for metal roofing and siding installations on post-frame or residential projects. This option balances durability, corrosion resistance, and color compatibility with charcoal gray roofs.

Buying Guide: Key Purchase Considerations

While all listed products share core benefits—strong metal-to-metal fastening, corrosion resistance, and color-matched heads—different designs serve different installation needs. Here are essential factors to compare when selecting charcoal gray roof screws:

• Length and thread design: Choose screws that penetrate the metal panels adequately without protruding excessively. Self-drilling options save time on rough framing and pre-drilled holes.
• Head design and torque resistance: V-neck or Lo-Root head designs can resist head twist-off under heavy torque, which is helpful for high-wind regions or challenging installations.
• Coating and UV resistance: Powder-coated finishes with UV inhibitors reduce chalking and color fading over time. Look for coatings that are environmentally stable and non-VOC when possible.
• EPDM washer and seal integrity: A robust EPDM washer provides sealing even when installed at angles. Ensure washers are backed by a compatible metal backing to prevent leaks.
• Corrosion protection: Zinc, zinc-aluminum, or other protective alloys (e.g., ZXL no rust) extend life in humid or coastal climates. Galvanization is common, but zinc-free options are sometimes color-matched for appearance.
• Material compatibility: Confirm the screw material matches roofing and siding substrates (steel, aluminum, or mixed-metal assemblies) to prevent galvanic corrosion.
• Environmental and disposal considerations: Many powder-coated screws are recyclable and free of VOCs, supporting green building goals.

In practice, for a charcoal gray metal roof, selecting a mix of mid-length and long-length screws with strong EPDM sealing and a durable powder coating provides versatility across panels and openings. Self-drilling options can expedite installation on pre-engineered buildings, while standard wood-binding variants excel on wood-backed structures or where panel overlap requires deeper penetration.

Engineered to perform under varying weather conditions, these products aim to minimize maintenance needs and wind-driven leaks. When choosing, consider your local climate, roof pitch, panel type, and any regulatory or warranty requirements from your contractor or manufacturer.

For best results, follow the manufacturer’s installation guidelines, maintain consistent screw alignment, and avoid over-tightening which may strip threads or deform washers. Regular inspection after severe weather can catch issues early and preserve the roof’s structural integrity for years to come.
