Simpson 10d 0.131 x 3" Preservative-Treated Wood Decking Nail in 304 Stainless Steel by Simpson Strong-Tie is engineered specifically for deck and dock construction where long-term durability against the elements is essential. Crafted from Type 304 stainless steel, this exterior decking nail delivers a corrosion-resistant fastening solution that holds up in demanding outdoor environments, keeping your deck or dock as structurally sound and lasting as your home's interior. The annular-ring shank design and larger 0.131" shank diameter make it a reliable choice for fastening both green and seasoned preservative-treated pine - resisting withdrawal and helping prevent nail heads from popping up over years of use.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for outdoor decking and dock applications, standing up to moisture, weather, and contact with preservative-treated lumber without degrading over time.
• Annular-ring shank - increases withdrawal resistance compared to smooth-shank nails, helping prevent nail heads from working loose or popping up through deck boards over the life of the structure.
• 0.131" shank diameter - larger than standard decking nails, allowing for easier penetration into both green (freshly cut) and seasoned preservative-treated pine without splitting the wood.
• Full round head with checkered pattern - the 9/32" diameter head blends naturally with wood grain texture and reduces glare from sunlight, giving your finished deck a cleaner, more professional appearance.
• Diamond point tip - facilitates easier driving and more precise nail placement, reducing the effort needed during installation and minimizing the risk of wood splitting at the point of entry.
• 10d penny size, 3" length - sized appropriately for standard deck board thickness, ensuring proper penetration depth and a secure, code-compatible connection in deck and dock framing applications.
• Made in the United States - domestically produced to Simpson Strong-Tie quality standards, offering confidence in consistent dimensional accuracy and material integrity across every nail.

Why This Product

• Built for preservative-treated wood compatibility - the 0.131" shank diameter and Type 304 stainless steel construction are specifically matched to the demands of treated lumber, where chemicals in the wood can accelerate corrosion in lesser materials and cause structural fastener failure over time.
• Annular-ring shank solves the nail-pop problem - unlike smooth-shank alternatives, the ring shank mechanically grips wood fibers for dramatically higher withdrawal resistance, keeping deck boards tight and flat for a longer service life.
• Checkered head serves both function and aesthetics - the textured full round head improves hammer contact for reliable seating while its wood-grain appearance reduces the visual impact of fastener heads on finished decking surfaces.
• Trusted Simpson Strong-Tie engineering for exterior structural applications - designed as part of a comprehensive fastener system for deck and dock projects, this nail pairs the right geometry, material, and surface profile to handle the unique stresses of outdoor wood construction.

Frequently Asked Questions

Why is Type 304 stainless steel recommended for preservative-treated wood decking applications?

Preservative treatments used in outdoor lumber contain chemicals that can accelerate corrosion in standard galvanized or uncoated fasteners over time. Type 304 stainless steel provides strong resistance to this type of chemical corrosion, helping maintain the structural integrity of the fastener connection throughout the life of the deck or dock.

What is the advantage of an annular-ring shank over a smooth shank for decking nails?

The annular-ring shank features raised rings along the shank that mechanically interlock with wood fibers as the nail is driven. This creates significantly higher withdrawal resistance compared to a smooth shank, meaning the nail is much less likely to work loose or cause nail-head pop-up over time - a common problem in deck boards subjected to seasonal moisture and temperature changes.

Can this nail be used in both green and seasoned preservative-treated pine?

Yes. The 0.131" shank diameter of this decking nail is specifically designed to allow for easy installation into both green (freshly milled, higher moisture content) and seasoned (dried) preservative-treated pine, providing flexibility for decking projects at various stages of lumber drying without requiring pilot holes in most applications.

Should I use Type 316 stainless steel instead of Type 304 for my project?

Type 304 stainless steel is well suited for most outdoor deck and dock applications. However, if your project is located in a seaside or coastal environment where salt air or saltwater exposure is a factor, Type 316 stainless steel offers superior corrosion resistance in those more aggressive conditions and may be the better choice for long-term performance near the ocean.
