Simpson 6d x 2" Annular Ring Shank Box Nail in 304 Stainless Steel is engineered for demanding fastening applications where corrosion resistance and long-term holding power are essential. Crafted by Simpson from Type 304 stainless steel, this 12-gauge box nail features an annular ring shank that dramatically increases withdrawal resistance compared to smooth-shank alternatives - making it a reliable choice for deck construction, siding, wood foundations, and other exterior or moisture-exposed assemblies where fastener pullout is a concern.

Key Features

• Type 304 Stainless Steel construction - delivers strong corrosion resistance for exterior, high-humidity, and treated-lumber applications where standard steel fasteners would rust and fail prematurely.
• Annular ring shank design - the threaded rings along the shank lock into wood fibers and significantly increase withdrawal resistance, keeping boards and panels firmly secured over time even as wood expands and contracts.
• Full round head with checkered pattern - the checker-textured head blends with natural wood grain, reduces sunlight glare, and accepts surface finishes and paints for a cleaner finished appearance.
• Diamond point tip - drives cleanly and accurately into wood, reducing splitting risk and making installation faster and more consistent.
• 12-gauge, 2" length (6d penny size) - a versatile mid-range dimension suited for box nail applications including sheathing, framing, and structural wood assembly work.
• Approximately 175 nails per pound - a predictable count-per-pound rate that helps with project planning and material estimation.
• Recommended for permanent wood foundations per ANSI/AF&PA Permanent Wood Foundations Design Specifications - meets recognized industry standards for critical structural applications.

Why This Product

• Purpose-built for corrosive environments: Type 304 stainless steel resists rust and oxidation in outdoor, coastal-adjacent, and high-moisture settings where plain steel or coated nails lose integrity over time.
• Superior holding power for structural and permanent assemblies: the annular ring shank provides far greater withdrawal resistance than a smooth shank, making these nails the right choice wherever boards must stay firmly connected under seasonal movement and load.
• Compatible with pressure-treated and specialty wood products: stainless steel does not react with the chemicals in pressure-treated lumber the way plain steel or galvanized fasteners can, preserving both the nail and the wood over the life of the structure.
• Made in the United States by a trusted fastening brand: Simpson's domestic manufacturing supports consistent quality control for a fastener used in permanent, load-bearing construction.

Frequently Asked Questions

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

Type 304 stainless steel offers strong general corrosion resistance and is well suited for most exterior, high-humidity, and pressure-treated lumber applications. Type 316 stainless steel provides superior corrosion resistance and is the recommended choice for seaside or marine environments where exposure to salt air or saltwater is a factor. For most inland or standard outdoor projects, 304 stainless is an excellent and cost-effective option.

Why does an annular ring shank nail hold better than a smooth shank nail?

The annular rings along the shank act like threads that grip wood fibers as the nail is driven. This mechanical interlock dramatically increases withdrawal resistance - meaning the nail resists being pulled back out under load, vibration, or wood movement - compared to a smooth-shank nail that relies primarily on friction alone.

Are these nails suitable for use with pressure-treated lumber?

Yes. Stainless steel is a recommended fastener material for pressure-treated lumber because it does not react with the preservative chemicals the way plain steel or some galvanized coatings can. These nails are also 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 box nails do?

The checker pattern on the full round head serves three practical purposes: it blends with the natural grain of wood for a less obtrusive appearance, it reduces glare from sunlight when used on exposed surfaces, and it accepts surface finishes and paints so the nail head can be finished to match the surrounding material.
