Simpson 1-1/2 in. 4d Smooth Shank Common Nail in 304 Stainless Steel is a 12-gauge fastener built for dependable performance in decking, framing, and general wood construction. Crafted from Type 304 stainless steel, this nail delivers reliable corrosion resistance for outdoor and structural applications where moisture exposure is a concern. The full round head and diamond point design make driving smooth and consistent, while the smooth shank profile suits a wide range of wood construction tasks requiring clean, controlled fastening.

Key Features

• Type 304 stainless steel construction - resists rust and corrosion in outdoor environments and general wood construction applications, extending the life of your fastening system
• 12-gauge shank diameter - provides substantial holding strength for structural framing and decking connections without over-stressing the surrounding wood fibers
• 1-1/2 in. length (4d penny size) - sized appropriately for a variety of light-to-medium construction tasks, offering secure penetration into standard lumber thicknesses
• Full round head with smooth head pattern - delivers broad bearing surface for a secure, flush-set finish that resists pull-through in wood applications
• Diamond point tip - enables easy nail starting and reduces wood splitting during driving, saving time and improving accuracy on the job
• Smooth shank profile - allows consistent, controlled driving by hand or with a hammer, suitable for general-purpose wood construction tasks
• Made in the United States - manufactured domestically, supporting consistent quality and reliable availability for professional and DIY builders alike

Why This Product

• Stainless steel for lasting outdoor performance - Type 304 stainless steel is recommended for construction of permanent wood foundations per ANSI/AWC Permanent Wood Foundations Design Specifications, making this nail a code-conscious choice for moisture-exposed structures
• Trusted Simpson brand quality - Simpson Strong-Tie is a recognized name in structural fastening, and this nail reflects that commitment to dimensional accuracy and material integrity for decking and framing work
• Right size for versatile applications - the 4d, 1-1/2 in. length covers a broad range of general wood construction needs, from decking boards to light framing connections, reducing the need for multiple fastener sizes on one job site

Frequently Asked Questions

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

Type 304 stainless steel provides solid corrosion resistance for most outdoor and general wood construction applications. Type 316 stainless steel offers superior corrosion resistance and is the recommended choice for seaside or coastal environments where salt air and moisture exposure are elevated. For most inland or standard outdoor projects, 304 stainless steel is an effective and appropriate material choice.

Are these nails suitable for use with permanent wood foundations?

Yes. Stainless steel nails, including those made from Type 304 stainless steel, are recommended for construction of permanent wood foundations by the ANSI/AWC Permanent Wood Foundations Design Specifications. Always consult the applicable design specification and local building code to confirm the right fastener material for your specific project.

What does the approximate count per pound mean for this nail?

The approximate count per pound for this 1-1/2 in. 12-gauge smooth shank nail is 228. This figure helps you estimate how many nails you will need based on the total weight of a quantity you purchase, which is useful for planning material quantities on larger projects.

Can these nails be driven by hand or do they require a pneumatic nailer?

These are common nails designed for hand-driving with a standard hammer. The smooth shank and diamond point tip make starting and driving straightforward. They are not designed for use in pneumatic nail guns, which typically require collated or strip-loaded fasteners in specific gauges and configurations.
