Simpson 10d x 3" Annular Ring Shank Roofing Nail in Type 316 Stainless Steel is engineered for demanding roofing applications where superior holding power and long-term corrosion resistance are non-negotiable. Manufactured in the United States by Simpson Strong-Tie, this full round head roofing nail features a diamond point for clean entry, a 0.375" head diameter for broad bearing surface against roofing materials, and an annular ring shank that mechanically locks into wood to resist withdrawal forces - delivering a fastening solution built to perform in coastal, marine, and other harsh outdoor environments.

Key Features

• Type 316 Stainless Steel construction - resists saltwater, chlorides, and aggressive atmospheric conditions, making this nail well-suited for coastal installations, marine environments, and applications involving treated lumber where standard galvanized fasteners would corrode prematurely.
• Annular ring shank design - the ring-threaded shank bites into wood fibers and plywood decking to dramatically increase withdrawal resistance compared to smooth-shank nails, keeping roofing material anchored even under wind uplift and thermal movement.
• Large 0.375" full round head - the broad, flat head distributes clamping force over a wider area of roofing material, reducing the risk of pull-through on tiles, slates, and underlayments.
• 3" (10d) length - the extended length penetrates through thicker roofing assemblies including heavy tiles and slates, providing deep embedment into the roof deck for a secure, long-lasting attachment.
• Diamond point tip - the sharp diamond point starts cleanly in wood and minimizes splitting, speeding installation and protecting the integrity of the substrate.
• 0.131" shank diameter - a 10-gauge shank provides the cross-sectional strength needed to resist lateral loads while still driving cleanly through dense roofing materials.
• Smooth head pattern - the clean, smooth head face sits flush against roofing material without snagging or tearing, preserving the waterproof integrity of the installation.
• Made in the United States - domestic manufacture supports consistent quality control and reliable material traceability across production batches.

Why This Product

• Purpose-built for high-corrosion roofing environments - Type 316 stainless steel contains higher molybdenum content than 304, giving it stronger resistance to pitting and crevice corrosion in salt spray and chemical exposure zones where roof fasteners are especially vulnerable.
• Ideal for heavy tile and slate roofing - the 3" length and annular ring shank together provide the depth and mechanical grip required when fastening thicker, heavier roofing materials that demand more from every nail.
• Reduces rework risk - the combination of withdrawal-resistant ring shank and a large bearing-surface head means fasteners stay put and materials stay secured, minimizing callbacks caused by fastener back-out or material pull-through.
• Complements Simpson Strong-Tie engineered systems - using Simpson fasteners alongside Simpson structural connectors ensures consistent, code-supportable fastener performance throughout the roofing assembly.

Frequently Asked Questions

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

Both 316 and 304 stainless steel offer excellent corrosion resistance, but Type 316 contains added molybdenum that provides stronger protection against saltwater, chlorides, and harsh chemical environments. For roofing applications in coastal or marine locations - where fasteners are exposed to persistent salt spray - Type 316 is generally the preferred choice. Type 304 is a strong option for less aggressive outdoor environments.

Why does the annular ring shank matter for roofing applications?

An annular ring shank has a series of rings along its length that interlock with wood fibers as the nail is driven. This mechanical engagement greatly increases withdrawal resistance compared to a smooth shank nail, keeping the nail firmly in place even under wind uplift, thermal cycling, and the weight of heavy roofing materials like tile and slate.

Is a 3" roofing nail suitable for installing tile and slate roofing?

Yes. The 3" length is specifically appropriate for attaching thicker roofing materials such as tiles and slates, as the longer shaft allows for sufficient penetration into the roof deck beneath. Always refer to the tile or slate manufacturer's recommendations for fastener length and count requirements specific to their product.

What does "approximately 78 nails per pound" mean in practical terms?

This approximate count is a reference figure that helps estimators and contractors calculate how many nails are needed for a given roofing project based on weight rather than counting individual pieces. Actual count per pound may vary slightly due to normal manufacturing tolerances in material density and dimensions.
