Simpson Strong-Tie 3-inch 10d Smooth Shank Common Nail in Type 304 Stainless Steel is a professional-grade fastener built for demanding wood construction and framing applications. Manufactured by Simpson Strong-Tie, this 9-gauge nail combines a full round head, diamond point, and smooth shank to deliver reliable penetration and holding power in structural wood-to-wood connections. Type 304 stainless steel construction provides strong corrosion resistance, making these nails well suited for exterior framing, decking substructures, and other outdoor wood construction projects where long-term performance matters.

Key Features

• Type 304 Stainless Steel material - resists corrosion in outdoor and moisture-exposed environments, helping connections stay secure over the long life of a structure.
• Smooth shank design - allows for clean, consistent drive into wood framing and general construction substrates, reducing split risk during installation.
• Full round head with 5/16-inch head diameter - maximizes bearing surface against the wood, distributing load effectively and reducing pull-through risk.
• Diamond point tip - guides the nail accurately on entry, enabling faster, more controlled driving through wood members.
• 9-gauge, 0.148-inch shank diameter at 3-inch length (10d penny size) - delivers the shank thickness and penetration depth recognized in standard framing and general construction specifications.
• Made in the United States - manufactured to Simpson Strong-Tie quality standards, giving builders confidence in consistent dimensional accuracy and material integrity.

Why This Product

• If you are framing exterior walls, structural decks, or other outdoor wood assemblies, the Type 304 stainless steel composition resists corrosion from weather exposure, keeping connections intact season after season.
• The 10d (3-inch) penny size and 9-gauge shank match widely accepted framing standards, so these nails integrate directly into typical wood-to-wood fastening schedules without requiring substitutions or adjustments.
• The full round head and diamond point combination means faster setting, cleaner seating, and a secure, flush finish - reducing rework on job sites where speed and precision both matter.
• Simpson Strong-Tie's focus on structural fasteners means this nail is engineered with the same attention to detail applied across their broader connector and fastener line, making it a trusted choice for professional framing and construction applications.

Frequently Asked Questions

What does the smooth shank mean for my application?

A smooth shank allows the nail to drive cleanly and consistently into wood framing without the added friction of a ring or spiral shank. This makes hand-driving and pneumatic driving efficient, and it is well suited to general framing and wood-to-wood fastening where straightforward, reliable penetration is the primary need.

Why choose Type 304 stainless steel for exterior wood construction?

Type 304 stainless steel provides meaningful corrosion resistance in outdoor environments where nails are exposed to moisture, weather cycles, and humidity. It is a practical choice for exterior framing and wood construction projects where long-term connection integrity is required.

What is the actual diameter of the nail shank?

The shank diameter is 0.148 inches, consistent with a standard 9-gauge nail. This dimension determines the nail's fit in pre-drilled holes and its compatibility with framing nailer specifications - confirm your nailer accepts 0.148-inch shank diameter nails before use.

How many nails are in a pound?

There are approximately 67 nails per pound for this 3-inch, 9-gauge, 10d smooth shank common nail. This count can help you estimate quantities needed for a framing or wood construction project based on the weight of nails purchased.
