Simpson Strong-Tie 5d x 1-3/4" Annular Ring Shank Roofing Nail in Type 304 Stainless Steel is engineered for demanding roofing applications where superior holding power and long-term corrosion resistance are essential. Crafted from 11-gauge Type 304 stainless steel, this nail delivers reliable performance when fastening roofing materials to wood members and plywood roof decks - offering the kind of withdrawal resistance that standard smooth-shank fasteners simply cannot match. The annular ring shank locks into wood fibers to resist pull-out, while the full round head spreads load across a wide bearing surface to keep roofing material firmly in place even under stress. Made in the United States, this fastener is a trusted choice for roofing professionals and contractors who need consistent, corrosion-resistant performance on every job.

Key Features

• Annular ring shank design - increases withdrawal resistance by mechanically interlocking with wood fibers, providing a significantly more secure attachment than smooth-shank nails on roofing applications
• Type 304 stainless steel construction - delivers high corrosion resistance, making this nail well-suited for outdoor roofing environments, coastal climates, and applications where moisture exposure is a concern
• Full round head with 3/8" diameter - provides a large, flat bearing surface that firmly secures roofing materials without punching through or tearing, reducing the risk of fastener pull-through
• Diamond point tip - drives cleanly into roofing substrates with reduced splitting, maintaining material integrity and speeding up installation
• 11-gauge, 0.120" shank diameter - offers a strong balance of shank thickness and driving ease for consistent hand or pneumatic nailing in roofing applications
• 5d penny size, 1-3/4" length - sized appropriately for standard roofing material attachment to typical decking thicknesses, minimizing overdriving and blowout
• Smooth head pattern - ensures clean, flush driving without leaving irregular surface marks that could compromise roofing material seating

Why This Product

• Built to resist the elements: Type 304 stainless steel construction means this nail holds up against rain, humidity, and the oxidizing conditions common in roofing environments - protecting both the fastener and the materials it secures over the long term.
• Superior pull-out performance: The annular ring shank is specifically designed to increase withdrawal resistance, meaning installed roofing materials stay anchored even under wind uplift and thermal expansion cycles.
• Reliable load distribution: The full round, smooth head spreads clamping force evenly across roofing material, reducing the chance of surface damage or fastener pull-through that can compromise a watertight installation.
• Trusted brand engineering: Designed by Simpson Strong-Tie to optimize holding power in roofing applications, this nail reflects the same engineering focus that professionals rely on across structural connectors and fasteners.

Frequently Asked Questions

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

The annular ring shank features ridges 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 far more resistant to being pulled back out - an important quality in roofing where wind uplift and material movement can put ongoing stress on fasteners.

Why is Type 304 stainless steel recommended for roofing nails?

Type 304 stainless steel provides a high level of corrosion resistance, which is critical in roofing applications where fasteners are exposed to moisture, humidity, and outdoor weathering over many years. Using stainless steel fasteners helps prevent rust staining on roofing materials and maintains the structural integrity of the fastened connection over the life of the roof.

What does the full round head design do for roofing performance?

The full round head with a 3/8" diameter provides a wider bearing surface than a smaller or clipped head nail. This extra surface area distributes the clamping force more evenly across the roofing material, helping to secure it firmly without tearing or punching through - which is especially important when fastening softer or thinner roofing substrates.

What does approximately 149 nails per pound mean for purchasing?

The approximate count of 149 nails per pound is a useful reference for estimating how many nails are included in a given weight of product. Because this is an approximate figure, actual counts may vary slightly. Use this number as a planning guide when calculating how many nails you need for a roofing project based on the weight options available.
