Simpson 2-inch 15 deg. Wire Coil Ring-Shank Siding Nail in Type 304 Stainless Steel is engineered for professional siding installation where long-term corrosion resistance and high-speed fastening performance are equally important. Crafted by Simpson Strong-Tie and made in the United States, this 6d, 13-gauge nail features an annular-ring shank that dramatically increases withdrawal resistance - keeping siding boards secure and reducing cupping over time. The 15 deg. wire-coil collation is compatible with many major manufacturers' pneumatic nailers, making it a practical choice for contractors who demand efficiency on the job site. Whether you are installing fiber cement boards, wood siding, or exterior cladding in demanding environments, this nail delivers dependable holding power in a corrosion-resistant package.

Key Features

• Type 304 Stainless Steel material - provides strong resistance to rust and corrosion in outdoor and high-moisture environments, protecting siding attachments for the long term without degrading over time.
• Annular-ring (ring-shank) shank design - increases withdrawal resistance compared to smooth-shank nails, creating a more secure hold that helps prevent siding boards from cupping or pulling away.
• 15 deg. wire-coil collation - compatible with many major pneumatic coil nailers, allowing faster and more efficient installation by reducing the need for manual reloading and driving effort.
• Full round head, 0.221-inch diameter - provides a generous bearing surface against siding material, distributing load evenly and reducing the risk of nail pull-through.
• Checkered head pattern - blends with wood grain texture, reduces glare from sunlight, and accepts surface finishes so the nail head is less visually obtrusive after installation.
• Diamond point tip - enables easier driving and cleaner penetration through fiber cement boards and wood siding with less splitting and reduced driving force required.
• Slender 13-gauge, 0.092-inch shank diameter - minimizes material displacement during driving, reducing the chance of splitting or cracking in fiber cement or wood substrates.
• Generous underhead fillet - allows nails to be driven flush or countersunk without crushing the surrounding siding material, producing a clean, professional finish.
• Made in the United States - produced domestically to consistent quality standards, giving professionals confidence in material integrity on every job.

Why This Product

• Purpose-built for fiber cement siding - the diamond point, slender 13-gauge shank, and ring-shank geometry are specifically suited to driving cleanly through fiber cement boards without cracking the material, making this nail a reliable choice where fiber cement is the primary substrate.
• Stainless steel longevity without compromising speed - Type 304 stainless steel construction delivers corrosion protection for exterior applications, while the wire-coil collation keeps installation fast and tool-compatible - you do not have to choose between durability and efficiency.
• Reduced siding movement over time - the annular-ring shank resists withdrawal forces that cause siding boards to cup, buckle, or loosen over years of seasonal expansion and contraction, reducing callbacks and maintenance concerns.
• Broad pneumatic tool compatibility - the 15 deg. wire-coil format works with many major manufacturers' coil nailers, so this nail integrates into existing tool setups without requiring specialized equipment.

Frequently Asked Questions

What makes this nail suitable for fiber cement siding applications?

This nail is specifically designed for use in fiber cement boards. The slender 13-gauge, 0.092-inch shank and diamond point tip allow the nail to drive cleanly through dense fiber cement material without causing cracking or splitting. The full round head with a generous underhead fillet ensures the nail can be driven flush or countersunk without crushing the surrounding board surface.

What is the difference between Type 304 and Type 316 stainless steel, and which should I choose?

Type 304 stainless steel provides strong corrosion resistance for most outdoor and exterior siding applications. For installations in coastal or seaside environments where exposure to saltwater and higher chloride concentrations is a concern, Type 316 stainless steel offers superior corrosion resistance and is the recommended choice for those conditions.

Is this nail compatible with my existing pneumatic coil nailer?

This nail uses a 15 deg. wire-coil collation format, which is compatible with many major manufacturers' pneumatic coil nailers. Verified compatible models include the Bostitch N64C, N66C, and N75C, as well as tools from Duo-Fast. Check your tool's documentation to confirm 15 deg. wire-coil compatibility before use.

How does the annular-ring shank improve siding performance compared to a smooth-shank nail?

The annular-ring (ring-shank) design features ridges along the shank that grip the surrounding material as the nail is driven, significantly increasing withdrawal resistance compared to a smooth-shank nail. This stronger grip helps prevent siding boards from pulling away, cupping, or loosening over time due to seasonal expansion and contraction - resulting in a more secure and lasting installation.
