#10 Metal Roofing Screws 3in Dark Brown - Durable Wood-to-Metal

In this review the focus is on a bulk pack of #10 metal roofing screws sold for corrugated and sheet metal roofing. The reviewer finds these screws best for DIYers and contractors fastening metal roofing to wood framing because of their sharp T17 point that starts quickly and the 1/2in EPDM washer that helps seal penetrations. The bottom line: these screws deliver reliable fastening and color-matched heads for a neat finish, making them a practical choice when installing or repairing metal roof panels.

Key Features

• 1/4in Hex Head: provides solid grip with standard drivers so installation is fast and consistent across long runs of roofing.
• 1/2in EPDM Washer: helps create a weather-resistant seal around each penetration to reduce leaks when seated properly.
• Sharp T17 Point: self-starting type point cuts into metal and wood substrate, reducing pilot hole needs and speeding up work.
• Painted Heads: two-part polyurethane paint on the heads offers a closer color match to many metal panels for a cleaner, less obtrusive finish.
• Galvanized Shafts: provide corrosion resistance on the screw body to extend service life in typical roofing environments.
• 3in Length (under head): suits attaching corrugated or standing seam panels to wood purlins and rafters with adequate thread engagement.

Who It's For

These screws are aimed at homeowners doing roof repairs, small contractors, and builders working with wood-framed metal roofs and corrugated siding. The combination of a T17 point and 3in length makes them well suited to fastening metal panels to wood purlins where secure thread engagement is needed.

Those who should look elsewhere include projects that require stainless steel fasteners for coastal environments or installations into metal substructure where self-drilling screws rated for metal-to-metal fastening would be more appropriate.

Pros & Cons

Pros

• Good value for bulk packs used on larger roofing runs, reducing trips for additional hardware.
• Painted hex heads help visually blend with roof panels for a neater appearance.
• EPDM washer combined with a hex head gives a dependable seal when tightened correctly.
• Galvanized shaft and sharp T17 point speed installation into wood without frequent predrilling.

Cons

• Rust resistance reports are mixed, so they may not be ideal for highly corrosive coastal sites.
• Color may vary slightly from panel manufacturers despite the polyurethane paint, so exact match is not guaranteed.

Our Verdict

For noncoastal roofing projects where wood is the substrate, these #10 metal roofing screws offer a balanced mix of performance, appearance, and value. The T17 point and galvanized shaft make installation efficient, while the EPDM washer and painted head provide weather protection and a cleaner look. They are a sensible choice for general metal-to-wood roofing work, though those needing maximum corrosion resistance should choose stainless alternatives.

Frequently Asked Questions

Are these screws suitable for metal-to-wood roofing?
Yes, the sharp T17 point and 3in length are designed to fasten metal panels to wood framing with reliable thread engagement.

Will the painted heads match my roof color?
The heads are painted with a two-part polyurethane to closely match many metal panels, but exact color can vary and may not be a perfect match.

Are these screws corrosion resistant?
The shafts are galvanized for corrosion resistance, but customers report mixed rust resistance in harsh environments, so stainless steel is recommended for coastal sites.
