Product Description
The Simpson Strong-Tie S16APBB Post and Beam Nail is a 16d, 3-1/2 in. annular ring shank nail crafted from Type 304 stainless steel for high-level corrosion resistance - making it an ideal fastener for outdoor construction, preservative-treated wood, and permanent wood foundation applications. At 9 gauge with a 0.148 in. shank diameter, this nail delivers serious holding power through its annular ring shank design, which dramatically increases withdrawal resistance to keep connections secure over time. The full round head features a distinctive checker pattern that blends naturally with wood grain, minimizes sunlight glare, and readily accepts surface finishes for a clean, professional result. A precision diamond point ensures smooth, efficient starts with every drive. Stainless-steel nails of this type are recommended for permanent wood foundation construction per the ANSI/AF&PA Permanent Wood Foundations Design Specifications. Each package contains 25 lb. of nails (approximately 56 nails per lb.), providing ample supply for large framing projects. Made in the United States.

Frequently Asked Questions
- Are these nails suitable for use with preservative-treated wood?
- Yes. Type 304 stainless steel nails like the S16APBB are recommended for construction involving preservative-treated wood and are specifically recommended for permanent wood foundation construction per the ANSI/AF&PA Permanent Wood Foundations Design Specifications.
- What makes the annular ring shank better than a smooth shank nail?
- The annular ring shank design significantly increases withdrawal resistance compared to a smooth shank, meaning the nail resists being pulled back out of the material over time. This provides a more secure, long-lasting attachment - particularly important in structural framing and outdoor applications where connections are subjected to load and movement.
- How many nails are included in one package, and what are the nail's key dimensions?
- Each package contains 25 lb. of nails, which is approximately 56 nails per pound. Each nail is 3-1/2 in. long (16d penny size), made from 9-gauge steel with a 0.148 in. shank diameter and a 5/16 in. full round head diameter.
- What is the purpose of the checker pattern on the nail heads?
- The checker pattern on the full round heads serves three practical purposes: it blends naturally with wood grain for a more refined appearance, reduces glare from sunlight on exposed surfaces, and allows the head to accept surface finishes so the nail can be painted or stained to match the surrounding material.
