Simpson Strong-Tie 2d x 1" Annular Ring Shank Roofing Nail in Type 304 Stainless Steel is engineered for roofing applications where both holding power and long-term corrosion resistance are critical. The annular ring shank design dramatically increases withdrawal resistance compared to smooth shank nails, keeping roofing materials firmly anchored to wood members and plywood roof decks even under demanding conditions. Made in the United States from Type 304 stainless steel, these roofing nails are a dependable choice for professional roofers and contractors working in environments where standard steel fasteners would be vulnerable to rust and degradation.

Key Features

• Annular ring shank - increases withdrawal resistance so roofing material stays securely fastened to the deck, even under wind uplift and thermal movement
• Full round, smooth flat head (3/8" diameter) - provides extra bearing surface against roofing material, reducing the chance of pull-through and creating a firm, flush installation
• Type 304 stainless steel material and finish - delivers higher levels of corrosion resistance compared to galvanized alternatives, making these nails well-suited for coastal, humid, and outdoor roofing environments
• Diamond point tip - drives cleanly and accurately into wood roof decks, reducing splitting and improving placement precision
• 10-gauge, 0.131" shank diameter - provides the structural strength needed to hold roofing substrates without bending during installation
• Approximately 212 nails per pound - allows for easy job-site quantity estimation so you can plan material needs accurately
• Made in the United States - manufactured to consistent quality standards by a trusted name in structural fasteners

Why This Product

• The annular ring shank sets these nails apart from smooth shank roofing nails by mechanically locking into wood fibers, making them the right choice when withdrawal resistance matters - particularly for securing roofing material to plywood roof decks subject to wind and moisture stress.
• Type 304 stainless steel construction means these nails resist rust and corrosion over the long life of a roof installation, reducing the risk of fastener failure that can allow roofing materials to loosen or leak.
• The large full round head distributes load across a wider surface area of the roofing material, minimizing pull-through while keeping the installation low-profile and clean.
• Simpson Strong-Tie's engineering focus on optimized holding power means this nail was purpose-designed for roofing - not a general-purpose fastener adapted for the application.

Frequently Asked Questions

What is the difference between an annular ring shank and a smooth shank roofing nail?

An annular ring shank has circular ridges along the length of the nail that mechanically interlock with wood fibers as the nail is driven. This significantly increases withdrawal resistance - meaning the nail is much harder to pull back out - compared to a smooth shank nail of the same size. For roofing applications where wind uplift and material movement are concerns, this added holding power is an important advantage.

Why is Type 304 stainless steel recommended for roofing nails?

Type 304 stainless steel provides higher levels of corrosion resistance than standard steel or even many galvanized coatings. In roofing applications, fasteners are continuously exposed to moisture, temperature cycling, and in some regions, salt air or chemical exposure. Using Type 304 stainless steel roofing nails helps prevent rust-related fastener failure that can cause roofing materials to loosen over time.

What does the full round smooth head design do for roofing installations?

The full round head with a 3/8" diameter provides a larger bearing surface than smaller or partial-round head nails. This extra surface area distributes holding force more evenly across the roofing material, reducing the likelihood of the nail head pulling through. The smooth head profile also ensures a clean, flush seating against the material surface during installation.

How many of these nails are in a pound, and how does that help with project planning?

There are approximately 212 nails per pound for this 2d x 1" size. Knowing the approximate count per pound makes it straightforward to estimate how much material you need for a roofing job by weight, helping you avoid under-ordering or carrying unnecessary excess to the job site.
