Simpson 5d x 1-3/4" 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 essential. Manufactured by Simpson Strong-Tie in the United States, this 11-gauge nail features a full round, smooth-faced head and a diamond point for clean, controlled driving into wood members and plywood roof decks. The annular ring shank design dramatically increases withdrawal resistance compared to smooth-shank alternatives, keeping roofing materials firmly anchored through seasonal movement and high-wind conditions. Type 316 stainless steel provides a higher level of corrosion protection than standard Type 304, making these fasteners a reliable choice for coastal, high-humidity, and chemically aggressive roofing environments.

Key Features

• Annular ring shank - dramatically increases withdrawal resistance compared to smooth-shank nails, ensuring roofing materials stay firmly secured to wood members and plywood decks over the long term.
• Full round, smooth head at 11/32" diameter - provides an extra-large bearing surface that spreads load across roofing material, reducing the risk of pull-through and delivering a clean, flush finish.
• Type 316 stainless steel material and finish - delivers elevated corrosion resistance that stands up to saltwater exposure, coastal climates, and chemically harsh roofing environments where standard or galvanized nails would degrade.
• 11-gauge shank at 0.120" diameter - balances driving ease with robust shear and withdrawal strength, appropriate for standard roofing substrates.
• Diamond point tip - promotes accurate, straight penetration into roofing substrates, reducing splitting risk and improving installation efficiency.
• 5d penny size at 1-3/4" length - sized appropriately for securing roofing materials to standard roof deck thicknesses without over-penetrating the substrate.
• Made in the United States - manufactured domestically to consistent quality standards expected from the Simpson Strong-Tie brand.

Why This Product

• When roofing nails are exposed to moisture, salt air, or chemically treated materials, corrosion causes fastener failure over time - Type 316 stainless steel construction addresses this directly, offering a higher tier of corrosion resistance than standard stainless or galvanized options.
• The annular ring shank solves a common roofing problem: nail withdrawal and "back-out" caused by thermal cycling and wind uplift forces - the ring shank's mechanical grip into wood fiber resists these forces far more effectively than smooth shanks.
• The oversized full round head at 11/32" distributes clamping force broadly across roofing materials, reducing the chance of pull-through that can compromise a watertight installation.
• With approximately 149 nails per pound, this nail is practical for estimating quantities needed for a roofing project, and the consistent 11-gauge, 1-3/4" specification ensures compatibility with standard roofing applications and nailer gauges.

Frequently Asked Questions

Why choose Type 316 stainless steel over Type 304 for roofing nails?

Type 316 stainless steel incorporates a higher level of corrosion resistance than Type 304, making it the preferred choice for coastal environments, areas with salt air exposure, and roofing applications where moisture and chemical exposure are ongoing concerns. For demanding or high-exposure installations, the added corrosion protection of Type 316 helps ensure long-term fastener integrity.

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

An annular ring shank features circumferential rings along the nail shaft that grip into wood fibers upon installation. This mechanical interlocking significantly increases withdrawal resistance compared to smooth-shank nails, which is especially important in roofing applications where wind uplift forces and seasonal wood movement can work fasteners loose over time.

What does the full round smooth head provide in a roofing nail?

The full round smooth head, measuring 11/32" in diameter, provides a broad, flat bearing surface that distributes clamping force evenly over the roofing material. This extra bearing area helps firmly secure roofing materials in place while reducing the risk of the nail head pulling through the material during installation or under load.

How many nails are in a pound of these 5d x 1-3/4" roofing nails?

There are approximately 149 nails per pound for this 5d x 1-3/4", 11-gauge Type 316 stainless steel annular ring shank roofing nail. This count can be used as a reference when estimating the quantity needed for your roofing project.
