Product Description
The Simpson 16d 3-1/2 in. 8-gauge annular ring shank common nail in Type 316 stainless steel is a heavy-duty fastener built for structural framing, decking, and foundation work where withdrawal resistance and long-term corrosion protection are non-negotiable. Engineered with a full round head, diamond point, and annular ring shank profile, this nail is purpose-built for permanent wood foundations, coastal construction, and high-moisture environments where standard carbon steel fasteners fall short.
Key Features
- Annular Ring Shank Profile - The ring shank geometry dramatically increases withdrawal resistance compared to smooth-shank nails, keeping fasteners locked in place under the stress and movement common in structural applications.
- Type 316 Stainless Steel Construction - Provides superior corrosion resistance in marine, waterfront, and salt-air environments, making this nail the preferred specification where Type 304 stainless steel or galvanized fasteners are insufficient.
- 8-Gauge, 16d Sizing with 7/16 in. Head Diameter - The full round head and robust 0.162 in. shank diameter deliver reliable load transfer and a secure mechanical connection in heavy-duty framing and foundation assemblies.
- Diamond Point Tip - Promotes accurate, controlled driving and reduces splitting risk in dense or engineered wood materials commonly used in permanent wood foundation construction.
- ANSI/AWC Permanent Wood Foundation Compatibility - Meets the stainless-steel fastener requirements called out in the ANSI/AWC Permanent Wood Foundations Design Specifications, giving builders confidence in code-appropriate fastener selection.
- Made in the United States - Domestic production supports consistent quality control and traceability for projects with material sourcing requirements.
Why This Product
- Built for the harshest corrosion environments - Type 316 stainless steel is the go-to alloy for seaside, coastal, and salt-air construction because it resists chloride-induced corrosion that compromises Type 304 stainless and galvanized alternatives over time.
- Maximized holding power for structural connections - The annular ring shank locks into wood fibers to resist pull-through and withdrawal forces, making these nails well-suited for demanding framing, decking, and foundation applications where joint integrity is critical.
- Meets recognized industry specifications - Compliance with ANSI/AWC Permanent Wood Foundations Design Specifications means builders and inspectors can select this fastener with confidence on projects requiring documented stainless-steel nail performance.
- A trusted Simpson fastener in a practical bulk format - From a brand with a long-standing reputation in structural connectors and fasteners, these nails come in a 10 lb box of approximately 440 nails - enough supply to support large framing or foundation scopes without frequent reordering.

Frequently Asked Questions
Why is Type 316 stainless steel recommended over Type 304 for coastal projects?
Type 316 stainless steel offers superior corrosion resistance compared to Type 304 stainless steel, making it specifically suited for seaside and coastal construction environments where salt air and moisture exposure are constant concerns. For projects in high-moisture or marine environments, the T16HACN10's 316 stainless steel composition provides a more reliable, long-lasting hold.
What advantage does the annular ring shank provide over a smooth-shank nail?
The annular ring shank profile dramatically increases withdrawal resistance compared to smooth-shank nails, providing a more secure and lasting attachment in wood framing and structural applications. This makes the T16HACN10 well suited for demanding construction uses where pull-out forces are a concern.
How many nails are included in a 10-pound box of T16HACN10?
Each 10-pound box contains approximately 440 nails, providing ample supply for large-scale framing, decking, and foundation projects.
What are the key specifications of the T16HACN10 nail?
The T16HACN10 is a 3-1/2 inch, 16d common nail made from Type 316 stainless steel with an 8-gauge diameter. It features an annular ring shank for enhanced withdrawal resistance, a full round head for maximum surface contact and load-bearing capacity, and a diamond point tip for clean, easy driving.
