Simpson Strong-Tie S11A125RNBP 15 Wire Coil, Full Round Head, Ring-Shank Roofing Nail 1-1/4 in. Type 304 (720-Qty)

Description

Product Overview

The Simpson Strong-Tie S11A125RNBP 1-1/4 in roofing nail is a premium fastener designed specifically for high‑performance roofing applications. Constructed from 304 stainless steel, the nail offers exceptional corrosion resistance, making it suitable for both asphalt shingles and synthetic slate roofing systems. Its flat head provides a clean, low‑profile finish while the diamond‑point tip eases penetration through tough roofing materials, reducing driver fatigue and improving installation speed.

Each nail features a precision‑engineered ring‑shank that dramatically increases withdrawal resistance, ensuring a secure attachment to OSB, plywood, or other roof deck substrates. The coil packaging of 720 nails delivers consistent feed performance in pneumatic nail guns, minimizing jams and maximizing productivity on large‑scale projects. With a weight of just three pounds per box, the product is lightweight enough for easy handling yet robust enough to meet demanding building code requirements.

Designed to meet ASTM standards for roofing fasteners, this model combines durability with ease of use. The 1-1/4 inch length strikes an optimal balance between penetration depth and material compatibility, allowing installers to achieve the required embedment without over‑driving. The stainless‑steel composition also provides a long service life, resisting rust and degradation even in harsh coastal environments.

Overall, the S11A125RNBP nail delivers a blend of strength, reliability, and convenience that makes it a top choice for contractors seeking a high‑quality, low‑maintenance solution for residential and commercial roofing projects.

Usage

These roofing nails are ideal for installing asphalt shingles, synthetic slate, and other common roofing materials on both new construction and re‑roofing projects. The flat head and diamond point allow for smooth driving through the shingle surface, while the ring‑shank design secures the nail firmly into the deck, preventing uplift from wind loads. Installers can confidently use this nail in a variety of climates, from hot, dry regions to humid, coastal areas, thanks to its 304 stainless‑steel construction.

When working with OSB or plywood roof decks, the 1-1/4 inch length provides sufficient embedment to meet most building code specifications without compromising the integrity of the deck material. The coil format is compatible with most standard pneumatic nail guns, enabling rapid placement of nails in tight spaces and on steep roof pitches. This efficiency reduces labor costs and shortens project timelines.

For DIY homeowners tackling smaller roofing repairs, the lightweight packaging and user‑friendly design make the S11A125RNBP nail an accessible option. The nails can be manually driven with a hammer for occasional spot repairs, though the recommended method remains pneumatic application for consistent results. Proper storage in a dry environment will preserve the stainless‑steel finish and maintain performance over time.

In professional settings, the nail’s corrosion‑resistant properties are especially valuable for roofs exposed to salt spray or industrial pollutants. By preventing rust formation, the fastener helps maintain the overall aesthetic and structural integrity of the roof, extending the lifespan of the roofing system and protecting the underlying building envelope.

FAQ

What roof deck materials are compatible with this nail?

The S11A125RNBP nail is designed for use with common roof deck substrates such as oriented strand board (OSB) and plywood. Its 1‑1/4 inch length provides adequate embedment to meet most building code requirements while avoiding over‑penetration that could weaken the deck.

Can these nails be used with a manual hammer?

While the nails are optimized for pneumatic nail guns to ensure consistent placement and speed, they can be driven manually with a hammer for occasional spot repairs. Manual installation may require more effort and could affect the nail’s head finish, so pneumatic application is recommended for the best results.

How does the 304 stainless steel improve performance?

304 stainless steel is highly resistant to rust and corrosion, especially in environments with moisture, salt spray, or industrial pollutants. This material choice helps maintain the nail’s structural integrity and appearance over the lifespan of the roof, reducing the likelihood of fastener failure.

What is the advantage of the ring‑shank design?

The ring‑shank creates multiple points of contact within the deck material, dramatically increasing withdrawal resistance. This design helps prevent nail uplift caused by wind loads, ensuring the roofing material stays securely attached even under severe weather conditions.

Is the coil packaging compatible with all pneumatic nail guns?

The 720‑count coil is sized to work with most standard pneumatic roofing nail guns used in the industry. Always verify the gun’s specifications for coil compatibility, but the majority of professional tools will accept this coil without modification.
