Metal Roofing Screw 12 x 1-1/2 in Zinc ReGrip - Reliable Replacement

In this review the Metal Roofing Screw 12 x 1-1/2 in Zinc ReGrip is assessed for contractors and DIYers who need a dependable replacement for failed roofing and siding fasteners. The bottom line: it is a practical, no-nonsense choice when replacing loose nails or small screws because the ReGrip design and EPDM washer provide a solid seal and easy installation with a 5/16 in hex driver; the galvanized finish also resists corrosion for exterior use. This review focuses on real-world use, durability, and where these screws make the most sense.

Key Features

• 5/16 in Hex Head: Provides firm driver engagement so screws can be driven quickly and with less cam-out on metal roofs and siding.
• ~9/16 in EPDM Washer: The washer creates a reliable weather seal around the head to reduce leaks on roof panels.
• .216 in Shaft (#12) Width: A stout shaft that replaces smaller nails or screws without enlarging existing holes excessively.
• 1-1/2 in Under Head Length: Suited for attaching metal to wood where a short shank is preferred to avoid over-penetration.
• Galvanized Zinc Finish: Grey galvanized coating offers corrosion resistance for exterior applications without paint.
• ReGrip Design: Intended to replace failed or loose fasteners, restoring holding power where previous nails or screws could not be tightened.

Who It's For

These screws are aimed at roofers, siding installers, and homeowners repairing barns, sheds, or older roofs where existing fasteners have loosened. They work well for projects that require a sealed head and a short penetration into wood backing, and for replacing multiple small failed fasteners with a single reliable option.

Those who need longer shanks, a painted finish to match panels, or metric-sized fasteners should look elsewhere. Also, if a project requires a larger head style consistently, be aware a small manufacturing variance may yield a 1/4 in head with a 5/8 in washer on some packs.

Pros & Cons

Pros

• Good sealing performance thanks to the EPDM washer that customers report helps stop leaks.
• Solid fit for replacing old nails or loose screws without re-drilling larger holes.
• Galvanized finish adds corrosion resistance for long-term exterior use.
• Clear value for money when buying in bulk for repairs or maintenance.

Cons

• The head and washer size can vary due to a manufacturing error, so some packs may arrive with a 1/4 in head and a 5/8 in washer.
• Grey galvanized color is unpainted, which may not match colored metal panels without touch-up.
