Simpson 3-1/4 in. 316 Stainless Steel Clipped Head Ring-Shank Nail, 31 deg. - 34 deg. Paper Tape Collated is a professional-grade framing nail from Simpson engineered for general framing applications where holding strength and severe-level corrosion resistance are non-negotiable. Built with an annular ring shank and fabricated from Type 316 stainless steel, this 12d nail is designed to perform in demanding, high-moisture, and salt-air environments where standard fasteners fall short. Paper tape collation and a 31 deg. - 34 deg. angle make it compatible with many major manufacturers' pneumatic nailers, keeping your installation fast and uninterrupted.

Key Features

• Smooth D-shaped clipped head - fits clipped-head pneumatic nailers and allows nails to be packed closer together in the magazine, reducing reload frequency on the job.
• Annular ring shank increases withdrawal resistance - the ridged shank grips surrounding material as the nail is driven, delivering a more secure attachment than smooth-shank alternatives in framing applications.
• Type 316 stainless steel construction provides severe-level corrosion resistance - makes these nails a reliable choice for coastal, seaside, and other high-moisture environments where lesser materials would degrade over time.
• Paper tape collation at 31 deg. - 34 deg. - compatible with many major manufacturers' pneumatic tools, reducing driving force and increasing installation speed on general framing work.
• Diamond point tip - promotes accurate nail placement and cleaner penetration, helping reduce splitting in framing lumber.
• 10 gauge, 3-1/4 in. length - sized for structural framing tasks where a robust, full-depth 12d nail is required to meet connection demands.
• 1,000 nails per package - a high-count quantity that supports extended work sessions and reduces downtime from restocking.

Why This Product

• Built for severe corrosion environments - Type 316 stainless steel is specifically suited for coastal, waterfront, and high-humidity applications where salt air and moisture exposure would compromise standard steel or hot-dipped fasteners, giving you long-term structural integrity without sacrificing holding power.
• Superior withdrawal resistance through annular ring-shank technology - the ring shank locks into the surrounding material in a way a smooth shank cannot, making this nail a strong choice for framing connections that need to resist movement, vibration, or seasonal wood expansion.
• Pneumatic tool compatibility for faster framing - the 31 deg. - 34 deg. paper tape collation works with many major manufacturers' pneumatic nailers, so crews can drive nails quickly and consistently without switching tools or collation types on the jobsite.
• A trusted fastener from Simpson - Simpson offers a wide variety of fasteners engineered to meet the requirements of every project type, and this collated ring-shank nail reflects that commitment to reliable, application-specific performance in demanding framing scenarios.

Frequently Asked Questions

What makes Type 316 stainless steel nails the right choice for coastal or high-moisture environments?

Type 316 stainless steel provides severe-level corrosion resistance, making these nails well-suited for seaside applications and other environments where exposure to moisture, salt air, or harsh conditions could compromise standard fasteners over time.

Why does an annular ring shank provide a stronger hold than a smooth shank?

The annular ring shank features a series of ridges along the shank that grip the surrounding material as the nail is driven, significantly increasing withdrawal resistance and providing a more secure attachment compared to a smooth-shank nail.

What pneumatic nailers are compatible with these 31 deg. - 34 deg. paper tape collated nails?

These nails are compatible with many major manufacturers' pneumatic tools.
