Simpson 3/4" Annular Ring Shank Roofing Nail in Type 316 Stainless Steel is a heavy-duty fastener engineered for demanding roofing applications where corrosion resistance and long-term holding power are essential. Manufactured in the United States by Simpson Strong-Tie, this roofing nail features a full round head with a smooth head pattern, a diamond point for clean penetration, and an annular ring shank that grips wood fibers tightly to resist withdrawal forces over time. Whether used in coastal environments, high-humidity climates, or applications involving pressure-treated lumber, the Type 316 stainless steel construction delivers reliable performance where standard fasteners fall short.

Key Features

• Type 316 Stainless Steel construction - provides superior resistance to saltwater, moisture, and chemical exposure, making this nail a reliable choice for coastal, marine, and corrosive environments where standard galvanized fasteners can fail prematurely.
• Annular ring shank design - the ring-patterned shank bites into wood fibers and resists pullout forces, creating a more secure attachment to wood members and plywood roof decks than smooth-shank alternatives.
• Full round head with smooth head pattern - delivers a large flat bearing surface that firmly distributes clamping force across roofing materials, reducing the risk of pull-through and keeping materials securely in place.
• Diamond point tip - pierces roofing substrates cleanly and with reduced splitting, making installation faster and protecting the integrity of the surrounding material.
• 10-gauge shank (0.131 in. diameter) - provides the structural body needed to drive securely through roofing materials without bending, supporting consistent installation performance.
• 0.375 in. head diameter - the wide head maximizes bearing surface contact on roofing underlayment, shingles, and similar materials, helping to prevent fastener pull-through under wind and load.
• Made in the United States - manufactured under consistent quality standards, giving contractors and builders confidence in dimensional accuracy and material integrity on every project.

Why This Product

• Built for environments where corrosion is a real risk - Type 316 stainless steel is widely recognized for its resistance to chloride-rich and chemically active environments, making this nail a smart choice for roofing projects near coastlines, in humid climates, or wherever long-term corrosion resistance is a priority.
• Annular ring shank means fasteners stay put - unlike smooth-shank nails that can back out over time due to seasonal wood movement, the annular ring profile locks into wood fibers and maintains holding strength through years of thermal expansion and contraction.
• Engineered by Simpson Strong-Tie for roofing applications - the combination of full round head geometry, ring shank, and diamond point reflects a design purpose-built for securing roofing materials rather than a generic nail repurposed for the job.
• Domestic manufacturing supports consistent quality - produced in the United States, this nail meets the dimensional and material expectations that professional roofing contractors rely on for code-compliant and structurally sound installations.

Frequently Asked Questions

What makes Type 316 stainless steel a good choice for roofing nails?

Type 316 stainless steel contains molybdenum, which gives it enhanced resistance to chlorides and corrosive agents compared to many other metals. This makes it particularly well-suited for roofing applications in coastal areas, high-humidity regions, or wherever exposure to moisture and chemicals could cause standard fasteners to corrode and lose holding power over time.

How does the annular ring shank improve performance compared to a smooth shank?

The annular ring shank features a series of rings along the nail body that lock into wood fibers as the nail is driven. This mechanical interlock significantly increases withdrawal resistance - meaning the nail resists being pulled back out - which is critical on plywood roof decks and wood members subject to wind uplift and seasonal movement.

What types of roofing applications is this nail appropriate for?

This nail is designed for securing roofing materials to wood members and plywood roof decks. Its large full round head provides extra bearing surface to hold roofing material firmly in place, and its 316 stainless steel construction makes it appropriate for applications where corrosion resistance is a key requirement, such as coastal or chemically active environments.

How do I determine how many nails I need for my project?

This nail has an approximate count of 281 nails per pound. By estimating the total number of fasteners required for your roofing project and dividing by 281, you can calculate the approximate weight needed. Select the pack size that best matches your project's requirements from the available options listed above.
