#14 Metal Roofing Screws 1-1/2in Ivy Green/Forest Green - Durable

In this review the focus is on a practical pack of #14 metal roofing screws sold in a 250-count box, aimed at anyone fastening corrugated metal to wood. The single biggest reason to consider these screws is their combination of a painted polyurethane head and a galvanized shaft with a sharp T17 point, which together deliver a tidy finish and reliable penetration for routine roofing projects. The review looks at fit, finish, corrosion protection, and ease of use for typical installations like sheds, porches, and pole barns.

Key Features

• 5/16 in Hex Head: The common hex head size provides a secure drive with standard sockets or impact drivers for fast, repeatable fastening.
• 1-1/2 in Length: The 1-1/2 in length under the head is well suited to attach single-layer metal roofing to wood purlins and rafters without excess protrusion.
• EPDM Washer: The ~9/16 in EPDM washer seals the hole around the shaft to reduce leaks when installed correctly on corrugated panels.
• Galvanized Shaft: Galvanization offers baseline corrosion resistance for outdoor roofing use in typical climates.
• Polyurethane Painted Head: The colored head is painted to closely match many metal roofing colors so finished panels look cohesive, keeping visible fasteners unobtrusive.
• T17 Sharp Point: The self-starting T17 point helps the screw penetrate metal and bite into wood quickly during installation with common power tools.

Who It's For

These screws are primarily for homeowners, contractors, and hobby builders installing metal roofing on houses, porches, sheds, pole barns, shops, and similar wood-structure projects. The painted head makes them a good choice when appearance matters on visible roofs.

Those working with thicker structural steel, requiring stainless steel fasteners, or installing in highly corrosive seaside environments should look for specialty fasteners designed for those conditions, as these are galvanized and intended for standard outdoor use.

Pros & Cons

Pros

• Good appearance from the polyurethane painted head that blends with many roofing colors.
• Effective penetration and quick fastening thanks to the sharp T17 type point.
• EPDM washer and hex head combine to create a solid, weather-resisting seal when installed properly.
• Galvanized shaft provides baseline corrosion resistance for general roofing projects.

Cons

• Some customers report mixed experience with self-tapping ability depending on metal thickness; pre-drilling thicker panels may be required.
• Painted finish may vary slightly from roofing brand colors, so exact color match is not guaranteed.
