Simpson 3" Premium Common Nail in 316 Stainless Steel is engineered for demanding fastening applications where ordinary nails fail - particularly in seaside, coastal, and other severe-exposure environments where corrosion resistance is critical. Crafted from passivated Type 316 stainless steel with a 9-gauge shank, this 10d nail delivers exceptional holding power and long-term durability in conditions that would quickly degrade standard or hot-dipped fasteners. Whether you are framing near saltwater, securing roof sheathing, or working with pressure-treated lumber in high-moisture settings, this nail is purpose-built to perform.

Key Features

• Type 316 stainless steel construction - provides superior resistance to corrosion, salt spray, and chemical exposure, making it the right choice for coastal and severe-exposure fastening applications
• Passivated finish - an additional surface treatment that maximizes corrosion resistance, extending service life in wet and marine environments beyond what unpassivated stainless provides
• Annular ring shank - increases pull-out resistance and delivers greater holding power compared to smooth-shank nails, keeping connections tight even under repeated load cycling
• Blunt diamond point - drives true and reduces board splitting, particularly useful when fastening near board edges or in denser wood species
• Circle pattern head - reduces surface glare and accepts paint or other surface finishes cleanly, resulting in a cleaner finished appearance on exposed applications
• 9-gauge shank diameter (0.148 in.) - provides the structural shank strength needed for common nail applications while maintaining compatibility with standard framing and sheathing
• 3-inch length (10d penny size) - a versatile length suited for framing, sheathing, and general construction fastening tasks
• ASTM F1667 compliant (T10) - meets recognized industry specifications for roof-sheathing ring-shank nails, supporting code-compliant installations
• Made in the United States - domestically manufactured to consistent quality standards

Why This Product

• Built for coastal and severe-exposure environments - Type 316 stainless steel is specifically recommended for seaside applications and other harsh conditions where standard galvanized or 304 stainless fasteners may corrode prematurely, giving builders confidence in the long-term integrity of their connections
• Holds tighter, longer - the annular ring shank is not just stronger on initial drive - it resists pull-out over time, meaning fastened assemblies stay secure even as lumber expands and contracts with moisture changes
• Reduces jobsite waste from board splitting - the blunt diamond point is engineered to drive true and minimize splitting, which means fewer rejected boards and cleaner installations, especially near board ends
• Code-supported performance - compliance with ASTM F1667 for roof-sheathing ring-shank nails means this nail is appropriate for use in applications requiring documented specification compliance

Frequently Asked Questions

Why is Type 316 stainless steel recommended over other nail materials for coastal applications?

Type 316 stainless steel contains molybdenum, which gives it enhanced resistance to chloride corrosion - the primary cause of nail degradation in seaside and salt-air environments. Combined with passivation, these nails are specifically suited to severe-exposure environments where standard galvanized or even 304 stainless fasteners may degrade over time.

What does the annular ring shank do, and why does it matter?

The annular ring shank features ridged rings along the shank that grip the wood fibers as the nail drives in. This mechanical interlock significantly increases pull-out resistance compared to a smooth shank, providing greater holding power in structural and sheathing applications - an important advantage anywhere connections are subject to uplift, racking, or cyclic loading.

Is this nail compliant with any recognized industry standards?

Yes. This nail complies with ASTM F1667 specifications for roof-sheathing ring-shank nails (T10), making it appropriate for use in applications where documented specification compliance is required.

What does "passivated" mean and how does it benefit performance?

Passivation is a chemical treatment applied to stainless steel that removes surface contaminants and reinforces the natural oxide layer on the metal. This process enhances the nail's corrosion resistance beyond what the base stainless steel alloy provides on its own, which is especially valuable in marine and other chemically aggressive environments.
