Product Description
Simpson S8APB5 Post and Beam Nail, Annular Ring Shank - 2-1/2 in. x .120 in. Type 304 Stainless Steel (5 lb.) is a Simpson Strong-Tie 8d framing nail engineered for post-and-beam construction and general framing applications where long-term holding power and corrosion resistance are critical. The annular ring shank dramatically increases withdrawal resistance for a secure, lasting connection, while the Type 304 stainless steel construction delivers high-level corrosion resistance suited to demanding outdoor and preservative-treated wood environments.

Frequently Asked Questions
- Why is an annular ring shank better than a smooth shank for post-and-beam applications?
- The annular ring shank increases withdrawal resistance compared to a smooth shank nail. This means the rings grip the wood fibers more aggressively, providing a more secure attachment that is better able to resist the forces that can cause a nail to pull out over time - a critical advantage in structural post-and-beam and framing applications.
- Why is Type 304 stainless steel recommended for outdoor and preservative-treated wood construction?
- Type 304 stainless steel provides high-level corrosion resistance, making these nails well-suited for exterior environments and contact with preservative-treated wood. They are specifically recommended for construction of permanent wood foundations per the ANSI/AF&PA Permanent Wood Foundations Design Specifications, where long-term durability against moisture and chemical exposure is essential.
- 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 with wood grain for a more natural appearance, reduces glare from sunlight on exposed surfaces, and allows the head to accept surface finishes such as stain or paint - making these nails a good choice for visible post-and-beam and outdoor structural work.
- How many nails are included in a 5 lb. package of the S8APB5?
- Each package contains 5 lb. of nails, with approximately 115 nails per pound, for a total of approximately 575 nails per package.
