Simpson 1-1/4 in. 3d Annular Ring Shank Common Nail in Type 316 Stainless Steel is a heavy-duty fastener engineered for wood-to-wood fastening and wood framing applications where corrosion resistance and holding strength are critical. Built from Type 316 stainless steel and featuring a full round head with a diamond point, this 14-gauge nail delivers the reliable, long-lasting performance that demanding exterior and seaside construction projects require. The annular ring shank design provides enhanced withdrawal resistance, keeping connections tight even under stress, making it an excellent choice for both structural framing and general fastening work in harsh or coastal environments.

Key Features

• Type 316 Stainless Steel material - offers superior corrosion resistance compared to standard stainless grades, making it the right choice for coastal, marine, and high-moisture environments where ordinary fasteners would corrode prematurely.
• Annular ring shank design - dramatically increases withdrawal resistance so fastened connections remain secure over time, reducing the risk of loosening in wood framing and structural applications.
• 14-gauge shank at 0.083 in. diameter - provides a strong, reliable hold with enough shank strength to handle demanding wood-to-wood fastening tasks without bending under driving pressure.
• Full round head at 7/32 in. diameter - distributes clamping load evenly across the wood surface, reducing the chance of the head pulling through and ensuring a flush, stable seat.
• Diamond point tip - penetrates wood cleanly and with less splitting, making it easier to drive nails near board edges or in tight framing situations.
• 1-1/4 in. length (3d penny size) - sized appropriately for light-duty framing connections and wood-to-wood fastening where a shorter, precise nail is needed to avoid over-penetration.
• Made in the United States - manufactured to consistent quality standards so you can rely on dimensional accuracy and material integrity from fastener to fastener.

Why This Product

• Built for seaside and high-humidity construction - Type 316 stainless steel is specifically recognized for its superior resistance to salt air, moisture, and corrosive conditions, making these nails the appropriate fastener choice when building or repairing structures in coastal or wet environments.
• Annular ring shank means connections that stay tight - unlike smooth shank nails that can work loose over time, the ring shank grips the wood fibers for increased withdrawal resistance, giving your framing and fastening work lasting structural integrity.
• A trusted Simpson Strong-Tie fastener - Simpson Strong-Tie is a widely recognized name in structural fastening and connectors, providing a broad range of fasteners engineered to meet the requirements of exterior and structural construction projects.
• Consistent count for project planning - with approximately 473 nails per pound, you can accurately estimate quantities needed for your framing or fastening project, reducing waste and unexpected shortfalls.

Frequently Asked Questions

What makes Type 316 stainless steel better suited for outdoor and coastal projects than other nail materials?

Type 316 stainless steel provides superior corrosion resistance compared to standard grades, making it highly effective in environments exposed to salt air, moisture, and other corrosive elements. For seaside construction or exterior applications where long-term performance matters, 316 stainless is the recommended choice to prevent premature rust and fastener failure.

What is an annular ring shank and why does it matter for wood framing?

An annular ring shank features ridged rings along the shank of the nail that grip the surrounding wood fibers as the nail is driven. This design significantly increases withdrawal resistance compared to a smooth shank nail, meaning the fastener holds much more securely against forces that would otherwise pull it back out. For wood framing and wood-to-wood fastening, this translates to a more stable, long-lasting connection.

What applications are these nails approved for?

These Simpson 1-1/4 in. 3d annular ring shank nails are approved for fastening wood-to-wood and for wood framing applications. Their corrosion-resistant Type 316 stainless steel construction makes them well suited for exterior and coastal environments where standard carbon steel fasteners would deteriorate.

How many of these nails are there per pound?

There are approximately 473 nails per pound. This count can help you estimate how much product you need for a given project, whether you are doing light-duty wood framing or a series of wood-to-wood fastening tasks.
