Simpson 3/4" Annular Ring Shank Roofing Nail in 304 Stainless Steel is a professional-grade fastener engineered for roofing applications that demand both exceptional holding strength and long-term corrosion resistance. Featuring a full round, smooth-head design with a diamond point, this nail drives cleanly through roofing materials and secures firmly into wood members and plywood roof decks. Crafted from Type 304 stainless steel, it delivers superior protection against rust and corrosion - making it a reliable choice for demanding outdoor environments where standard galvanized fasteners may fall short.

Key Features

• Type 304 Stainless Steel construction - provides superior corrosion resistance compared to standard coatings, keeping roofing fasteners structurally sound in moisture-exposed and weather-facing installations.
• Annular ring shank design - dramatically increases withdrawal resistance, locking the nail securely into wood members and plywood roof decks to prevent loosening over time.
• Full round, large flat head - delivers extra bearing surface area to firmly secure roofing material in place, reducing the risk of pull-through under load.
• Diamond point tip - enables clean, efficient penetration into roofing substrates with reduced splitting, speeding up installation.
• Smooth head pattern - allows consistent, clean seating against roofing material surfaces for a flush, professional finish.
• Made in the United States - domestic manufacturing supports consistent quality standards and traceability for construction projects.

Why This Product

• Built for corrosion-prone roofing environments - Type 304 stainless steel resists oxidation and rust in outdoor, wet, and high-humidity conditions where lesser fasteners degrade and fail, protecting the integrity of the roof over its full lifespan.
• Engineered for maximum withdrawal resistance - the annular ring shank mechanically locks into wood fibers, making these nails far more resistant to pull-out than smooth shank alternatives - a critical advantage in wind-uplift and high-load roofing applications.
• Optimized head geometry for roofing material - the large, flat full round head provides a wide bearing surface that holds roofing materials firmly without damaging or punching through them, reducing installation errors and callbacks.
• Trusted Simpson brand quality - Simpson is a recognized name in structural fasteners and connectors, and this roofing nail reflects the same engineering standards applied across their product line, giving contractors and builders confidence in performance.

Frequently Asked Questions

What makes the annular ring shank better than a smooth shank for roofing applications?

The annular ring shank features a series of rings along the shank that mechanically interlock with wood fibers as the nail is driven. This significantly increases withdrawal resistance compared to a smooth shank nail, meaning the fastener is much harder to pull out under load. In roofing applications - where wind uplift and material weight create ongoing stress on fasteners - this added holding power is a key performance advantage.

What is the difference between Type 304 and Type 316 stainless steel for roofing nails?

Both Type 304 and Type 316 stainless steel offer strong corrosion resistance for outdoor and roofing applications. Type 304 provides superior corrosion protection suitable for most roofing environments. Type 316 contains added molybdenum and is generally used in more aggressive environments such as coastal or marine settings. Simpson offers both options to match the appropriate level of corrosion protection to the specific installation conditions.

What roofing materials are these nails designed to fasten?

These nails are designed to secure roofing materials to wood members and plywood roof decks. The large flat full round head provides extra bearing surface to hold roofing material firmly without pull-through, and the 3/4 in. length and 0.131 in. shank diameter are engineered to suit standard roofing fastening applications. Always refer to roofing material manufacturer recommendations for nail size and type requirements specific to your project.

Is this roofing nail made in the United States?

Yes. This Simpson roofing nail is manufactured in the United States, reflecting consistent quality control standards. Domestically produced fasteners can simplify documentation for projects that require materials of U.S. origin or that specify domestic sourcing as part of project compliance requirements.
