Product Description
Simpson 3-1/4 in. 12d Annular Ring Shank Common Nail in 304 Stainless Steel is built for structural and construction applications where both corrosion resistance and holding power are non-negotiable. The annular ring shank design grips surrounding wood fibers as the nail is driven, delivering significantly greater withdrawal resistance than smooth-shank nails, while the Type 304 stainless steel composition keeps the fastener performing reliably even in moisture-prone or chemically treated wood environments.
Key Features
- Annular ring shank design - increases withdrawal resistance so fasteners stay locked in place under load, reducing the risk of pull-out in demanding structural connections
- Type 304 stainless steel construction - resists corrosion from moisture and treated lumber contact, making these nails a sound long-term choice for permanent installations
- Full round head with diamond point - the full round head maximizes bearing surface for a secure seat, while the diamond point drives cleanly and consistently through framing lumber
- Meets ANSI/AWC Permanent Wood Foundations Design Specifications - these ring shank common nails are specifically recommended for permanent wood foundation construction, giving builders a code-aligned fastener option
- 6 gauge, 12d penny size at 3-1/4 in. length - sized for common structural framing tasks where a heavy-duty common nail with superior holding ability is required
Why This Product
- Dual-performance advantage - combining an annular ring shank with Type 304 stainless steel means buyers get both enhanced mechanical holding power and corrosion resistance in a single fastener, eliminating the need to compromise between the two
- Specification-ready for permanent wood foundations - alignment with ANSI/AWC Permanent Wood Foundations Design Specifications gives contractors and builders confidence that these stainless ring shank nails meet recognized industry requirements without additional verification
- Domestically produced by a trusted brand - Simpson manufactures these nails in the United States, supporting consistent quality control for projects where fastener reliability is critical
- Suited for corrosive and high-moisture environments - where standard steel fasteners would rust or degrade over time, the 304 stainless steel composition keeps structural connections intact in applications exposed to moisture or chemically treated wood

Frequently Asked Questions
What makes an annular ring shank nail different from a smooth-shank nail?
The annular ring shank features a series of rings along the shank that grip the surrounding wood fibers as the nail is driven. This design significantly increases withdrawal resistance compared to a standard smooth-shank nail, resulting in a stronger, more secure attachment that is less likely to pull out over time.
Why is Type 304 stainless steel used for these nails?
Type 304 stainless steel provides reliable corrosion resistance, making these nails suitable for applications where exposure to moisture or treated lumber could cause standard steel fasteners to rust or degrade. For seaside applications or environments requiring superior corrosion resistance, Type 316 stainless steel is recommended instead.
Are these nails appropriate for permanent wood foundation construction?
Yes. Stainless-steel nails such as these are recommended for construction of permanent wood foundations in accordance with the ANSI/AWC Permanent Wood Foundations Design Specifications, making them a code-appropriate choice for that application.
How many nails are included in a 25 lb box?
Each 25 lb box contains approximately 1,000 nails, providing a generous supply for large framing or structural fastening projects.
