Simpson 5d x 1-3/4" Annular Ring Shank Roofing Nail in 304 Stainless Steel is engineered for demanding roofing applications where both holding power and long-term corrosion resistance are essential. Manufactured by Simpson Strong-Tie and made in the United States, this 10-gauge nail features a large full round head for maximum bearing surface and an annular ring shank that dramatically increases withdrawal resistance - keeping roofing materials firmly secured to wood members and plywood roof decks even under cyclic loading and severe weather exposure. Type 304 stainless steel construction makes this nail an ideal choice for coastal environments, high-humidity installations, and applications where pressure-treated lumber or moisture-rich conditions would cause standard fasteners to corrode prematurely.

Key Features

• Type 304 Stainless Steel material - delivers superior corrosion resistance compared to galvanized alternatives, making it well suited for wet environments, coastal roofing projects, and contact with treated lumber
• Annular ring shank design - increases withdrawal resistance significantly over smooth-shank nails, providing a more secure and lasting attachment to wood members and plywood roof decks
• Large full round head (0.375" diameter) - creates extra bearing surface that helps prevent the nail from pulling through roofing materials, improving long-term fastener performance
• 10 gauge, 1-3/4" length (5d) - sized for standard roofing applications with a shank diameter of 0.131", delivering a strong connection without splitting thinner roofing substrate
• Diamond point tip - penetrates roofing material cleanly and consistently, reducing splitting and simplifying installation into wood roof decks
• Smooth head pattern - allows flush seating against roofing material surfaces for a clean, professional finish that does not compromise the integrity of the roofing layer

Why This Product

• Purpose-built for corrosion-prone roofing environments - Type 304 stainless steel resists rust and oxidation in conditions where galvanized nails would degrade, reducing the risk of fastener failure over the lifetime of the roof
• Annular ring shank solves the withdrawal problem - unlike smooth-shank roofing nails, the ring shank profile mechanically locks into wood fibers, preventing loosening caused by thermal expansion, wind uplift, or moisture cycling
• Made in the United States - domestic manufacture supports consistent quality control and reliable material traceability for construction professionals who specify U.S.-made fasteners
• Trusted Simpson Strong-Tie engineering - designed to meet the performance expectations of roofing contractors and builders who rely on fasteners that work alongside structural connectors and engineered wood products

Frequently Asked Questions

What is the difference between an annular ring shank and a smooth shank roofing nail?

An annular ring shank features a series of rings along the shank that grip wood fibers mechanically 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 under wind uplift, thermal movement, or moisture-related stress - making it the preferred choice for secure roofing attachments.

Why is Type 304 stainless steel recommended for roofing applications?

Type 304 stainless steel provides a high level of corrosion resistance, making it suitable for roofing installations exposed to rain, humidity, coastal air, and pressure-treated lumber. Unlike standard galvanized nails, 304 stainless steel resists rust over the long term, helping to maintain the integrity of the roof fastening system throughout the life of the roof.

What roofing materials and substrates is this nail designed to fasten?

This 5d x 1-3/4" roofing nail is designed to fasten roofing materials to wood members and plywood roof decks. The full round head provides extra bearing surface to firmly secure roofing material, and the annular ring shank anchors securely into the wood substrate below.

Is this nail suitable for use in coastal or high-moisture environments?

Yes. The Type 304 stainless steel construction makes this nail well suited for high-humidity, coastal, and wet roofing environments where lesser materials would corrode. The 10-gauge, annular ring shank design also ensures the nail maintains its hold even when the surrounding wood structure experiences repeated moisture cycling.
