Simpson 2" 6d Annular Ring Shank Common Nail in Type 316 Stainless Steel is a heavy-duty fastener engineered for wood-to-wood connections and framing applications where long-term holding power and corrosion resistance are critical. Built by Simpson Strong-Tie from 11-gauge Type 316 stainless steel, this nail delivers outstanding withdrawal resistance thanks to its annular ring shank design - making it a trusted choice for exterior construction, seaside environments, and any project demanding a secure, lasting attachment. The diamond point drives cleanly through dimensional lumber, while the full round head provides a broad bearing surface for strong, reliable connections.

Key Features

• Type 316 Stainless Steel material - offers superior corrosion resistance compared to standard stainless grades, making it the right choice for coastal, saltwater-exposed, and chemically demanding outdoor environments
• Annular ring shank - mechanically interlocks with wood fibers to dramatically increase withdrawal resistance, keeping connections tight even under cyclic loading and moisture-driven wood movement
• 11-gauge shank diameter (0.120 in.) - provides a robust cross-section for reliable shear strength in structural wood framing and general fastening applications
• Full round head (17/64 in. diameter) - delivers a wide bearing surface that helps distribute load across the wood surface and reduces the chance of pull-through
• Diamond point - cuts cleanly into wood for easier driving and reduced splitting, especially important when fastening near board edges
• Made in the United States - produced domestically to consistent quality standards expected for structural and exterior fastening work

Why This Product

• Built for seaside and harsh outdoor conditions - Type 316 stainless steel is specifically recommended for coastal and saltwater-exposed applications where standard galvanized fasteners would fail prematurely, giving exterior structures a longer, more reliable service life
• Engineered for maximum holding power - the annular ring shank increases withdrawal resistance beyond what a smooth-shank nail can provide, reducing the risk of fastener back-out in high-stress or moisture-exposed wood connections
• Trusted brand for structural fastening - Simpson Strong-Tie's exterior nail line is specifically designed to provide corrosion-resistant fastening solutions that help exterior living spaces last as long as the interior of a home
• Versatile fit for common wood framing tasks - the 2-inch length and 6d penny size make this nail well-suited for a broad range of wood-to-wood fastening and light framing applications, offering flexibility across jobsite tasks

Frequently Asked Questions

Why should I choose Type 316 stainless steel over other nail materials for exterior projects?

Type 316 stainless steel provides superior corrosion resistance that makes it especially well-suited for seaside applications and environments with high moisture or chemical exposure. Unlike standard fasteners that can corrode and weaken over time, 316 stainless steel maintains structural integrity in harsh outdoor conditions, helping exterior wood connections last for the long term.

What is the advantage of an annular ring shank compared to a smooth shank nail?

The annular ring shank features rings along the shank that mechanically grip wood fibers as the nail is driven, significantly increasing withdrawal resistance. This means the nail is far more resistant to pulling back out under load, vibration, or moisture-related wood movement compared to a smooth-shank common nail of the same size - making it a stronger choice for framing and structural wood-to-wood connections.

What does the diamond point on this nail do?

The diamond point is designed to cut cleanly into wood during driving rather than simply pushing fibers aside. This reduces the force needed to drive the nail and helps minimize splitting of the wood, which is particularly beneficial when fastening near the ends or edges of boards.

Is this nail suitable for use with pressure-treated or chemically treated lumber?

Type 316 stainless steel is among the most corrosion-resistant fastener materials available and is recommended by Simpson Strong-Tie for applications requiring superior corrosion resistance. Its high resistance to chemicals and salt makes it a strong candidate for use with treated lumber in exterior environments where corrosion is a concern. Always verify compatibility with the specific treatment chemistry used in your lumber.
