#14 Metal Roofing Screws 1 in Ash Gray Hex Head - Durable Fixings

In this review of the #14 Metal Roofing Screws, the bottom line is simple: these screws are for anyone fitting corrugated metal roofing to wood who needs fast, reliable fastening and good value. The reviewer found the self-starting T17 point and galvanized shaft made installing sheets to purlins and OSB quick, and the painted polyurethane heads plus EPDM washers gave a tidy, weather-resistant finish. For contractors, handy homeowners, and small builders who want durable roof fasteners in a familiar ash gray color, these screws deliver the essentials without fuss.

Key Features

• 1 in length: The 1 in length under the head is well suited to typical sheet metal over wood decks, offering secure bite without excessive protrusion.
• #14 shaft: The.242 in shaft diameter provides extra shear strength for heavy gauge roofing panels and reduces wobble during drive-in.
• EPDM washer: The ~9/16 in EPDM washer seals the screw penetration to limit water entry and helps preserve the roof under thermal movement.
• Polyurethane coated head: The painted hex head is color matched to many metal roofing finishes so fasteners blend with panels for a neater appearance.
• T17 sharp point: The self-starting T17 point taps through metal into wood quickly, reducing pre-drilling and speeding installation.
• Galvanized finish: Galvanization gives baseline corrosion resistance suitable for a wide range of exterior roofing applications.

Who It's For

These screws are aimed at professional roofers, contractors, and homeowners installing corrugated or sheet metal roofing onto wood substrates such as purlins or OSB. They suit projects from small sheds and porches to larger pole barns where a heavy-duty #14 fastener and a sealing washer are desirable.

Those who should look elsewhere include installers working into metal-to-metal applications that require specialized self-drilling screws, or projects needing stainless steel fasteners for highly corrosive coastal environments where galvanization may not be sufficient.

Pros & Cons

Pros

• Good build quality and function: customers report they fasten steel roof to OSB reliably and hold well under load.
• Value for money: a 250-count pack gives a large supply for typical roof projects at a reasonable price point.
• Sealing and appearance: the EPDM washer and painted head help prevent leaks and blend with roofing colors.
• Ease of use: the T17 point starts quickly and cuts installation time by reducing the need for pre-drilling.

Cons

• Color variance: the painted polyurethane coating is matched to many brands but color may vary, so exact color match is not guaranteed.
• Not stainless: galvanized finish is protective but may not suit very aggressive coastal or chemical environments.

Our Verdict

Frequently Asked Questions

Are these screws self-drilling into metal?
They use a sharp T17 self-starting point designed to tap metal into wood, but they are not intended as heavy-duty metal-to-metal self-drilling screws.

Will the washer prevent leaks?
The ~9/16 in EPDM washer provides a reliable seal around the screw head to reduce water intrusion when installed properly into a solid substrate.

How close is the color match?
The polyurethane coated head is painted to closely match many metal roofing colors, but exact shade may vary and perfect matching is not guaranteed.
