Simpson Strong-Tie 10d Preservative-Treated Wood Decking Nail in 304 Stainless Steel is engineered for lasting performance in exterior deck and dock construction. Built with a 0.148-inch shank diameter and annular-ring shank geometry, this corrosion-resistant fastener drives smoothly into both green and seasoned preservative-treated pine, delivering the holding power your outdoor living projects demand. The Type 304 stainless steel construction resists the chemical reactions caused by modern wood preservatives, making it a trusted choice for decks, docks, and other outdoor structures where long-term durability matters.

Key Features

• Type 304 Stainless Steel material - resists corrosion when used with preservative-treated lumber, extending the service life of your deck or dock fasteners in outdoor conditions
• Annular-ring shank - increases withdrawal resistance so nail heads are less likely to pop up over time, keeping your deck surface smooth and safe underfoot
• 0.148-inch shank diameter (Gauge 9) - larger shank profile penetrates both green and seasoned pressure-treated pine with ease, reducing splitting and installation effort
• Full round head with checkered pattern - the textured head blends with natural wood grain and reduces sunlight glare, giving your deck a cleaner finished appearance
• Diamond point tip - sharpened geometry makes driving easier and more controlled, even in dense or treated wood
• 3-inch (10d) length - sized for proper penetration depth in standard deck board applications, meeting common decking fastening requirements
• Made in the United States - domestic manufacturing supports consistent quality and material standards for structural fastening applications

Why This Product

• Preservative-treated lumber contains chemicals that can corrode standard steel fasteners rapidly - the Type 304 stainless steel construction of this nail is specifically suited for contact with treated wood, helping your deck frame stay structurally sound over years of outdoor exposure.
• The annular-ring shank design locks into wood fibers far more securely than a smooth-shank nail, which means fewer nail pops and less maintenance on your finished deck surface over time.
• With a 0.148-inch shank diameter, this fastener is built wider than many standard nails, allowing it to penetrate even wet or freshly treated (green) lumber without excessive force or pre-drilling in most applications.
• The checkered full round head provides a firm strike surface for consistent driving while the textured face blends into the wood surface, making it a practical choice for visible decking where aesthetics matter alongside performance.

Frequently Asked Questions

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

Type 304 stainless steel provides strong corrosion resistance suitable for most preservative-treated wood deck and dock applications away from the coast. For seaside or marine environments where exposure to salt air and salt water is constant, Type 316 stainless steel offers superior corrosion resistance and is the recommended choice for those more demanding conditions.

Why does this decking nail have an annular-ring shank instead of a smooth shank?

The annular-ring shank design features ridges along the shank that lock into wood fibers as the nail is driven, significantly increasing withdrawal resistance compared to a smooth-shank nail. This helps prevent nail heads from popping up over time, which is especially important in deck surfaces subject to seasonal wood movement and heavy foot traffic.

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

Yes. The 0.148-inch shank diameter is specifically designed to allow easier installation into both green (freshly treated, higher moisture content) and seasoned (dried) preservative-treated pine, reducing the force needed to drive the nail without compromising holding strength once set.

Why does the head of this decking nail have a checkered pattern?

The checkered head pattern serves two practical purposes: it helps the nail head blend visually with natural wood grain for a cleaner appearance on finished deck surfaces, and it reduces glare from sunlight reflecting off the nail head - a common issue with polished fasteners on exposed outdoor decks.
