Simpson 10d 0.131 x 3" Preservative-Treated Wood Decking Nail in 316 Stainless Steel by Simpson Strong-Tie is engineered specifically for deck and dock construction, delivering a corrosion-resistant fastening solution that keeps outdoor living spaces structurally sound for the long term. Featuring an annular-ring shank for superior withdrawal resistance and a full round checkered head for a clean, low-glare finish, this exterior nail is built to perform in demanding conditions - including coastal and marine environments where standard fasteners fail prematurely. Made in the United States from Type 316 stainless steel, it offers the durability needed for both green and seasoned preservative-treated pine applications.

Key Features

• Type 316 stainless steel material - provides superior corrosion resistance against saltwater, chemicals, and harsh outdoor exposure, making it ideal for seaside and marine environments where standard fasteners would corrode rapidly.
• Annular-ring shank - increases withdrawal resistance to help prevent nail heads from popping up over time, extending the service life of deck and dock projects.
• Larger 0.131" shank diameter - penetrates both green and seasoned preservative-treated pine with ease, reducing splitting and simplifying installation.
• Full round head with checkered pattern - the checkered head blends naturally with wood grain and reduces glare from sunlight, delivering a cleaner finished appearance on decking surfaces.
• Diamond point tip - enables easier driving and more precise nail placement, reducing the effort required during installation.
• 10d, 3" length - sized appropriately for secure fastening of standard decking boards, providing deep penetration into framing members for a strong hold.
• 9/32" head diameter - sized to seat cleanly into decking lumber without over-driving, maintaining surface integrity while holding boards firmly in place.

Why This Product

• Built for the toughest outdoor environments - Type 316 stainless steel is the material of choice for coastal and marine applications where saltwater exposure, humidity, and preservative-treated lumber chemicals would degrade lesser fasteners, helping your deck or dock last as long as the structure it supports.
• Withdrawal resistance that holds over time - the annular-ring shank grips wood fibers more aggressively than smooth-shank nails, resisting the upward movement caused by seasonal wood expansion and contraction - a common cause of nail pop in deck boards.
• Compatible with preservative-treated lumber - the larger shank diameter is specifically designed to drive cleanly into both green (wet) and seasoned preservative-treated pine without splitting the board, addressing one of the most common frustrations in deck construction.
• American-made quality from a trusted fastener brand - manufactured in the United States, this Simpson Strong-Tie decking nail reflects the consistency and engineering precision that contractors and builders rely on for structural fastening applications.

Frequently Asked Questions

Why should I use Type 316 stainless steel nails for my deck or dock project?

Type 316 stainless steel offers superior resistance to corrosion from saltwater, moisture, and the chemicals present in preservative-treated lumber. It is specifically recommended for seaside and marine environments where standard galvanized or zinc-coated fasteners are prone to rust and premature failure. For deck and dock projects exposed to harsh outdoor conditions, 316 stainless steel provides a long-lasting, reliable fastening solution.

What is an annular-ring shank and why does it matter for decking?

An annular-ring shank features raised ridges along the shank that grip wood fibers as the nail is driven in. This mechanical interlock significantly increases withdrawal resistance compared to smooth-shank nails. For decking applications, this means nail heads are far less likely to pop up over time as the wood expands and contracts seasonally - helping maintain a flat, safe deck surface with less maintenance.

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

Yes. The 0.131" shank diameter is specifically sized to allow easy installation into both green (freshly treated, moisture-laden) and seasoned (dried) preservative-treated pine. This makes the nail versatile enough for new deck construction using freshly treated lumber as well as repair work on older, dried decking material.

What does the checkered head pattern on this nail do?

The checkered pattern on the 9/32" full round head serves two practical purposes: it blends more naturally with wood grain for a cleaner finished appearance, and it reduces glare from sunlight on the nail head surface. This makes the fastener less visually intrusive on finished decking while still providing a proper seating surface for a secure, flush installation.
