Simpson 4-1/2 in. 30d Annular Ring Shank Common Nail in Type 304 Stainless Steel is a heavy-duty fastener engineered for wood-to-wood connections and framing applications where long-term holding strength and corrosion resistance are essential. Built to Simpson Strong-Tie's exacting standards, this 6-gauge stainless steel nail features an annular ring shank that dramatically increases withdrawal resistance compared to smooth-shank alternatives, making it a dependable choice for exterior framing, permanent structures, and other demanding fastening projects exposed to moisture and the elements.

Key Features

• Annular ring shank design - increases withdrawal resistance significantly over smooth-shank nails, providing a more secure and lasting attachment in wood framing and structural connections
• Type 304 stainless steel material and finish - delivers strong corrosion resistance for outdoor and moisture-exposed applications, helping fastened assemblies hold up over the long term without the rust or staining common with uncoated nails
• 6-gauge wire diameter with 0.203 in. shank - offers robust shear strength appropriate for heavy framing and load-bearing wood-to-wood connections
• Full round head at 7/16 in. diameter - maximizes bearing surface against the wood face for a secure, slip-resistant seat and broad load distribution
• Diamond point tip - enables clean, accurate driving with minimal wood splitting, reducing waste and rework during installation
• 4-1/2 in. length (30d penny size) - provides substantial penetration depth for connecting thick framing members, ensuring strong mechanical engagement throughout the joint
• Made in the United States - manufactured to consistent quality standards by a trusted structural fastener brand

Why This Product

• The annular ring shank grips wood fibers along its entire length, resisting pull-out forces that would otherwise loosen smooth nails over time - making this nail the right call for exterior framing and permanent wood structures where joint integrity cannot be compromised.
• Type 304 stainless steel construction means this nail stands up to wet and outdoor environments where standard steel fasteners would corrode, stain, or fail - ideal for decks, outdoor living spaces, and other exterior assemblies exposed to rain and humidity.
• At 4-1/2 in. (30d), this nail is sized for serious framing work - long enough to penetrate multiple members and create strong, durable connections in wood-to-wood applications that demand more than a standard common nail can provide.
• The full round head and diamond point combination speeds up installation by reducing splitting and ensuring a flat, flush drive - saving time and material on large framing projects.

Frequently Asked Questions

What is the advantage of an annular ring shank over a smooth shank nail?

The annular ring shank features ridges along the shank that grip wood fibers as the nail is driven, increasing withdrawal resistance compared to a standard smooth-shank nail. This means the fastened joint is less likely to loosen or pull apart over time, which is especially important in exterior framing and structural wood-to-wood connections subject to movement, moisture cycling, and load stress.

Why is Type 304 stainless steel recommended for exterior fastening applications?

Type 304 stainless steel provides strong corrosion resistance, making it suitable for outdoor environments and assemblies exposed to moisture where standard steel nails would rust and degrade. Using a stainless steel nail helps preserve both the structural integrity of the connection and the appearance of the surrounding wood over the life of the structure.

What types of projects is this 4-1/2 in. 30d nail best suited for?

This nail is designed for wood-to-wood fastening and wood framing applications. Its 4-1/2 in. length and 6-gauge diameter make it appropriate for connecting thick framing members where deep penetration and strong mechanical engagement are required. The stainless steel construction makes it particularly well-suited for exterior and outdoor structural assemblies.

Approximately how many nails are there per pound?

There are approximately 22 nails per pound for this 4-1/2 in. Type 304 stainless steel annular ring shank common nail. Use this figure to estimate quantity needs for your project when purchasing by weight.
