Simpson 1-inch 2d Smooth Shank Common Nail in 304 Stainless Steel is a 15-gauge fastener built for dependable performance in decking, framing, and general wood construction. Crafted from Type 304 stainless steel, this nail delivers long-lasting corrosion resistance that makes it a trusted choice for both interior and exterior applications where moisture exposure and wood preservatives are a concern. The full round head and diamond point work together to drive cleanly and seat securely, giving contractors and builders a reliable fastener for a wide range of structural and finish work.

Key Features

• Type 304 stainless steel construction - resists rust and corrosion in outdoor environments and when used with pressure-treated or treated lumber, extending the life of the fastened connection
• 15-gauge shank diameter of 0.072 in. - provides a balance of slender profile and structural strength, reducing wood splitting while maintaining holding power
• 1-inch length (2d penny size) - ideal for lighter-duty fastening tasks, thin materials, and applications where a shorter nail is required for flush or recessed driving
• Smooth shank design - allows for straightforward driving in a variety of wood species and construction contexts, making installation efficient with standard tools
• Full round head with smooth head pattern - delivers broad bearing surface and clean seating, reducing the risk of the fastener pulling through the material
• Diamond point tip - promotes accurate starting and consistent penetration, reducing deflection during driving and keeping work precise
• 3/16-inch head diameter - ensures solid material contact and a neat finished appearance on exposed surfaces
• Made in the United States - domestic manufacturing supports consistent quality standards across every nail

Why This Product

• Corrosion-resistant stainless steel for lasting performance - Type 304 stainless steel holds up against moisture and the chemicals found in treated lumber, making these nails well-suited for outdoor decking projects and wood construction exposed to the elements
• Right-sized for precision work - the 1-inch, 15-gauge profile fills the gap between staples and heavier common nails, giving builders the right fastener for thinner stock, overlays, and detail work without overdriving
• Trusted Simpson brand quality - Simpson is a recognized name in structural fasteners and connectors, and these nails reflect the same commitment to dimensional accuracy and material integrity that professionals rely on
• Smooth shank for versatile application - the smooth shank makes these nails adaptable across a broad range of wood construction tasks, from general framing to finish applications where clean removal or repositioning may be needed

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 corrosion resistance suitable for most outdoor and treated-lumber applications. Type 316 stainless steel provides a higher level of protection and is recommended for seaside or coastal environments where exposure to salt air and saltwater is a factor. If your project is not in a marine or high-salinity environment, 304 stainless steel is a capable and cost-effective choice.

Is a smooth shank nail appropriate for structural wood construction?

Smooth shank nails are widely used in general wood construction and decking applications. The smooth shank allows for efficient driving and is suitable for a broad range of fastening tasks. For applications requiring higher withdrawal resistance - such as decking boards under heavy load cycles - a ring shank or spiral shank nail may be worth considering depending on the project's requirements.

What does the "2d" penny size designation mean?

"2d" is the traditional nail sizing designation, also called the penny size. For this nail, 2d corresponds to a 1-inch length. Penny sizes are a standardized way to identify nail length that has been used in the construction industry for centuries, and 2d is one of the shorter sizes, making it well-suited for thin materials and detail fastening work.

Approximately how many of these nails are in one pound?

Due to the small 1-inch length and 15-gauge profile, there are approximately 807 nails per pound. This high count per pound makes them practical for projects requiring a large number of fasteners in a compact, lightweight format.
