Simpson 6d x 2" Preservative-Treated Wood Decking Nail in Type 304 Stainless Steel is engineered by Simpson Strong-Tie for demanding outdoor fastening applications where corrosion resistance and long-term holding power are essential. Built with an annular-ring shank and a checkered full round head, this exterior nail is purpose-built for deck and dock construction using both green and seasoned preservative-treated pine - delivering a secure, lasting connection that stands up to the elements over time.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for exterior, outdoor, and pressure-treated lumber applications, helping fasteners maintain integrity through repeated wet/dry cycles
• Annular-ring shank design - dramatically increases withdrawal resistance compared to smooth-shank nails, helping prevent nail heads from popping up over time and extending the service life of deck and dock surfaces
• Larger 0.120" shank diameter at 11 gauge - allows easier penetration into both green and seasoned preservative-treated pine without splitting or excessive driving force
• Checkered full round head pattern - blends visually with wood grain, reduces glare from sunlight, and provides a clean finished appearance on deck surfaces
• Diamond point tip - promotes easier, more controlled driving even in dense or fibrous treated lumber, reducing installation effort
• 6d penny size at 2" length - a standard decking nail size that provides reliable penetration depth for typical deck board fastening applications
• 9/32" head diameter - wide enough for a firm surface grip that resists pull-through while keeping a low-profile appearance on finished decking
• Made in the United States - domestic manufacturing supports consistent quality standards for professional and residential construction projects

Why This Product

• Built for preservative-treated wood compatibility - the Type 304 stainless steel construction resists the corrosive chemicals found in pressure-treated lumber, making these nails a reliable choice where standard bright or galvanized fasteners may degrade prematurely.
• Engineered to stay put - the annular-ring shank grips the wood fibers along its entire length, significantly resisting the withdrawal forces that cause nail pops on decks and docks exposed to seasonal temperature swings and moisture.
• Designed for efficient installation - the combination of the larger shank diameter and diamond point tip means these nails drive smoothly into treated pine in various moisture conditions, reducing installer fatigue and speeding up the job.
• A purpose-specific solution from a trusted fastener brand - Simpson Strong-Tie developed this nail specifically for deck and dock projects, so every design detail - from the head pattern that blends with wood grain to the ring shank that resists popping - directly addresses the real-world challenges of outdoor wood fastening.

Frequently Asked Questions

Why should I use Type 304 stainless steel nails for pressure-treated decking?

Preservative-treated lumber contains chemicals that can corrode standard fasteners over time, leading to staining and structural weakening. Type 304 stainless steel resists this chemical corrosion, helping your deck or dock fasteners maintain strength and appearance through years of outdoor exposure.

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

An annular-ring shank features ridged rings along the nail's shank that lock into wood fibers as the nail is driven. This dramatically increases withdrawal resistance compared to smooth-shank nails, which means the nail holds tighter over time and is far less likely to work loose or cause nail pops on deck surfaces.

Can these nails be used in both green and seasoned preservative-treated pine?

Yes. The larger 0.120" shank diameter and diamond point tip are specifically designed to penetrate both green (freshly treated, higher moisture content) and seasoned (dried) preservative-treated pine, making these nails versatile for a range of deck and dock construction conditions.

Is Type 304 stainless steel appropriate for seaside or saltwater environments?

Type 304 stainless steel provides good corrosion resistance for most outdoor applications. For seaside locations or environments with direct saltwater exposure, Type 316 stainless steel - which offers superior resistance to chlorides and salt - is the recommended choice.
