Simpson 5d x 1-3/4" Annular Ring Shank Box Nail in 304 Stainless Steel is a professional-grade fastener from Simpson, engineered for demanding construction applications where corrosion resistance and holding power are essential. The annular ring shank design delivers significantly greater withdrawal resistance compared to smooth shank nails, making these stainless steel box nails an ideal choice for decking, siding, exterior trim, and permanent wood foundation construction. Crafted from Type 304 stainless steel, these nails resist rust and corrosion in outdoor, high-moisture, and chemically treated lumber environments - providing a lasting, reliable connection without staining or degrading surrounding wood surfaces.

Key Features

• Type 304 Stainless Steel construction - resists rust, corrosion, and staining in outdoor, wet, and treated-lumber applications, extending the life of the fastened assembly
• Annular ring shank design - dramatically increases withdrawal resistance compared to smooth shank nails, creating a more secure and durable connection that holds under load and movement
• Checkered head pattern - blends naturally with wood grain, minimizes glare from sunlight, and accepts stains and surface finishes so nail heads remain visually unobtrusive
• Full round head profile - maximizes bearing surface on the wood for a strong, positive hold without over-driving or splitting
• Diamond point tip - penetrates wood cleanly and efficiently, reducing splitting risk even near board edges
• 13-gauge, 5d penny size at 1-3/4" length - sized appropriately for box nail applications where minimizing wood splitting while maintaining holding strength is critical
• Recommended for ANSI/AF&PA Permanent Wood Foundations - meets the specifications required for permanent wood foundation construction, supporting code-compliant structural assemblies

Why This Product

• Built for corrosion-prone environments: Type 304 stainless steel holds up in exterior, coastal-adjacent, and high-humidity conditions where carbon steel or electroplated fasteners would rust and fail prematurely - protecting both the fastener and the surrounding wood.
• Superior grip where smooth shanks fall short: The annular ring shank mechanically locks into wood fibers, resisting pull-out forces caused by seasonal wood movement, wind loads, and heavy use - a critical advantage in decking, siding, and foundation work.
• Finish-friendly for visible applications: The checkered head pattern is designed to blend with wood surfaces and accept paints or stains, making these nails well-suited for finish carpentry and exterior trim where appearance matters.
• Made in the United States: Domestic manufacturing supports consistent quality control for a fastener used in critical structural and exterior applications.

Frequently Asked Questions

What is the difference between Type 304 and Type 316 stainless steel for these nails?

Type 304 stainless steel offers strong general-purpose corrosion resistance and is well-suited for exterior, outdoor, and treated-lumber applications. Type 316 stainless steel provides superior corrosion resistance and is recommended for seaside or marine-adjacent environments where exposure to salt air or saltwater is a concern. If your project is located near the ocean or in a high-salinity environment, Type 316 is the preferred choice.

Why use an annular ring shank nail instead of a smooth shank nail?

The annular ring shank features a series of rings along the shank that lock mechanically into wood fibers as the nail is driven. This significantly increases withdrawal resistance - the force required to pull the nail back out - compared to a smooth shank nail of the same size. This makes annular ring shank nails an excellent choice for applications subject to movement, vibration, or uplift forces, such as decking, siding, and permanent wood foundation construction.

Are these nails compatible with pressure-treated lumber?

Yes. Stainless steel nails are widely used with pressure-treated lumber because they resist the corrosive effects of the preservative chemicals used in treated wood. Type 304 stainless steel provides reliable corrosion resistance in treated-lumber assemblies, and stainless steel fasteners are specifically recommended for permanent wood foundation construction per the ANSI/AF&PA Permanent Wood Foundations Design Specifications.

What does the checkered head pattern on these nails do?

The checkered pattern on the full round head serves multiple practical purposes: it blends with the natural grain of wood to reduce visual prominence, minimizes glare from sunlight in exposed outdoor applications, and allows the head to accept paints, stains, and other surface finishes - making these nails a good fit for finish work, decking, and exterior trim where a clean final appearance is important.
