Product Description
The Simpson 2-1/4 in. 7d Annular Ring Shank Common Nail in Type 316 Stainless Steel is built for wood-to-wood fastening applications where corrosion resistance and long-term holding power are non-negotiable. Offered by Simpson and packaged in a 25 lb. bulk quantity, this 11-gauge common nail pairs a diamond point for clean, consistent driving with an annular ring shank profile that locks into wood fibers to resist pull-out forces that smooth-shank nails simply cannot match. Whether you are framing structural assemblies, building permanent wood foundations, or working in environments where moisture and harsh conditions are constant concerns, this nail delivers the secure attachment and durability that demanding projects require.
Key Features
- Annular ring shank - increases withdrawal resistance compared to smooth-shank alternatives, locking the nail firmly in place for a more secure, lasting connection in wood framing and wood-to-wood fastening applications.
- Type 316 stainless steel construction - provides severe-level corrosion resistance, keeping fasteners structurally sound in harsh exterior environments, high-moisture conditions, and chemically aggressive settings where standard steel would degrade.
- Recommended for permanent wood foundation construction - stainless-steel nails of this type are specifically called out by the ANSI/AWC Permanent Wood Foundations Design Specifications, giving builders confidence in code-appropriate fastening.
- Full round head design - maximizes bearing surface against the wood face, distributing load effectively and reducing the risk of the nail head pulling through under stress.
- Diamond point tip - promotes straight, efficient driving and reduces the likelihood of splitting the workpiece, saving time and minimizing material waste on the job.
- 25 lb. bulk packaging - provides a high nail count (approximately 133 nails per pound) that keeps larger framing and foundation projects moving without constant restocking interruptions.
- Made in the United States - supports consistent manufacturing quality standards, as noted in the product data, giving contractors added assurance on commercial and residential projects alike.
Why This Product
- Severe-level corrosion protection where it counts most - Type 316 stainless steel goes beyond basic exterior-grade finishes, making these nails a reliable choice for permanent wood foundations, coastal construction, and any application where long-term fastener integrity is critical.
- Superior grip that resists pull-out - the annular ring shank mechanically interlocks with wood fibers, delivering meaningfully higher withdrawal resistance than smooth-shank nails and keeping connections tight over the life of the structure.
- Specification-compliant for permanent wood foundations - alignment with the ANSI/AWC Permanent Wood Foundations Design Specifications means these nails satisfy recognized industry standards, reducing guesswork for builders working on code-sensitive projects.
- Efficient bulk value for high-volume work - with roughly 133 nails per pound across a 25 lb. quantity, this package is sized for professional use, minimizing downtime and keeping framing and wood-to-wood fastening work on schedule.

Frequently Asked Questions
What makes Type 316 stainless steel suitable for exterior and corrosion-prone environments?
Type 316 stainless steel provides severe-level corrosion resistance, making these nails well-suited for harsh exterior environments, seaside applications, and other settings where standard fasteners would be prone to rust or degradation over time.
Are these nails approved for use in permanent wood foundation construction?
Yes. Stainless-steel nails are recommended for construction of permanent wood foundations by the ANSI/AWC Permanent Wood Foundations Design Specifications, and the T7ACNB meets that requirement as a Type 316 stainless steel fastener.
Why choose an annular ring shank nail over a smooth-shank nail?
The annular ring shank profile dramatically increases withdrawal resistance compared to smooth-shank alternatives, ensuring a more secure and lasting attachment in wood-to-wood fastening applications where holding power is critical.
What are the key dimensions and specifications of this nail?
This nail measures 2-1/4 inches in length (7d penny size), has a shank diameter of 0.120 inches, and is made from 11-gauge Type 316 stainless steel. It features a full round head with a 17/64-inch head diameter and a diamond point tip. It is sold in a 25 lb. bulk quantity.
