Simpson 1-1/4 in. x 0.12 Smooth-Shank 15 deg. Wire Coil Roofing Nails in Type 304 Stainless Steel are built for roofing professionals who need a fastener that stands up to demanding weather conditions without sacrificing driving consistency. These 11-gauge, 3d penny nails feature a smooth shank, full round head, and diamond point, and are configured in a 15 deg. wire coil for use with a wide range of professional pneumatic coil roofing nailers. Engineered to perform in asphalt and synthetic slate roofing installations, they deliver the corrosion resistance and mechanical reliability that high-volume roofing work demands.

Key Features

• Type 304 Stainless Steel construction - provides superior corrosion resistance against moisture and weather exposure, helping fasteners maintain their integrity over the life of the roof
• Full round head with smooth head pattern - creates a broad bearing surface that distributes load evenly across roofing materials, reducing the risk of pull-through
• Diamond point tip - allows for easier nail penetration and minimizes splitting in roofing substrates during high-speed pneumatic driving
• Smooth shank profile - enables cleaner, faster driving with consistent results when used with compatible coil roofing nailers
• 15 deg. wire coil configuration - ensures compatibility with a broad range of professional pneumatic nailer models, reducing downtime from collation mismatches
• Domestic origin - these nails are made in the United States, reflecting a commitment to consistent quality and manufacturing standards

Why This Product

Frequently Asked Questions

What type of nailer is compatible with these roofing nails?

These nails are configured in a 15 deg. wire coil, making them compatible with professional pneumatic coil roofing nailers that accept 15 deg. wire coil collation. Always verify your nailer's specifications for coil angle and gauge compatibility before use.

Why are Type 304 Stainless Steel nails recommended for roofing applications?

Type 304 Stainless Steel provides superior corrosion resistance compared to standard steel or galvanized fasteners, making these nails well suited for roofing environments where exposure to moisture and weather can cause lesser materials to rust or degrade over time.

What do the shank and head specifications mean for performance?

These nails feature a smooth shank, which allows clean and consistent penetration through roofing materials, and a full round head with a 3/8 in. diameter, which provides excellent holding power and a broad bearing surface. The diamond point further aids in easier driving and helps reduce material splitting during installation.

How many nails are included in one package, and what does that mean for a roofing job?

Each package contains 2,400 nails in a single coil, which supports high-volume roofing work by reducing the frequency of reloads. This makes the pack practical for professional roofing projects where consistent output and minimal downtime are important.
