Simpson 1-3/4" 15 deg. Wire Coil Ring Shank Roofing Nail in Type 304 Stainless Steel is engineered for professional roofing applications where speed, holding power, and long-term corrosion resistance are essential. Designed by Simpson Strong-Tie, this 5d, 11-gauge annular-ring shank nail is collated at 15 deg. in a wire coil format for use with pneumatic roofing nailers, making it an efficient choice for asphalt roofing and synthetic slate installations. The Type 304 stainless steel construction provides lasting protection against rust and oxidation in demanding outdoor environments, giving roofers and contractors the confidence of a fastener that performs now and holds up for years.

Key Features

• Type 304 Stainless Steel material - resists corrosion and oxidation in outdoor roofing environments, extending the service life of the fastener and the roof assembly it secures
• Annular-ring shank design - increases withdrawal resistance so the nail maintains a firm grip in OSB or plywood roof decks, reducing the risk of fastener back-out over time
• Full round head with 3/8" head diameter - provides a large bearing surface that holds roofing materials securely against the deck without tearing through the material
• 15 deg. wire coil collation - allows fast, continuous driving with many major pneumatic roofing nailers, reducing installation time and driver effort on large roofing projects
• Diamond point tip - enables easier nail starting and cleaner penetration through roofing substrates, reducing splitting and improving driving consistency
• 11-gauge wire at 0.120" shank diameter and 1-3/4" length - matches the dimensional requirements for standard roofing fastener specifications in asphalt and synthetic slate applications
• Smooth head pattern - minimizes surface marking on roofing materials while still delivering a flush, code-compliant installation
• Made in the United States - manufactured domestically, supporting consistent quality control and reliable availability for professional roofing contractors

Why This Product

• For roofers working with asphalt shingles or synthetic slate, the combination of ring shank holding power and full round head bearing surface addresses two of the most common fastener failure points - pull-through and back-out - in a single nail
• The 15 deg. wire coil format is compatible with many major manufacturers' pneumatic coil nailers, meaning this nail fits into the tools most roofing crews already own without requiring special equipment
• Type 304 stainless steel construction is suited for roofing applications where exposure to moisture and weather would quickly corrode a standard steel or electroplated nail, protecting both the fastener and the surrounding roofing material
• Simpson Strong-Tie's broad collated nail line means this roofing nail is part of an engineered fastener system, giving contractors confidence in consistent dimensional tolerances and collation quality across every coil

Frequently Asked Questions

What types of roofing materials is this nail designed for?

This nail is ideal for asphalt and synthetic slate roofing applications. Its annular-ring shank provides superior holding in OSB and plywood roof decks commonly used beneath these roofing materials, and the full round head distributes load to prevent pull-through.

Which pneumatic nailers are compatible with this 15 deg. wire coil roofing nail?

This nail is compatible with many major manufacturers' pneumatic coil roofing nailers. Specific compatible tools include models from Bosch (RN175), Bostitch (RN46), DeWalt (D51321), Hitachi (NV45AB2, NV45AE), Makita (AN453), Max (CN445R, CN450R), Paslode (R175-C, CR175C), Porter Cable (RN175A), Ridgid (R175RND), and Senco (RoofPro 455XP).

Why use Type 304 stainless steel for roofing nails instead of standard steel?

Type 304 stainless steel resists corrosion and oxidation in wet, outdoor environments where standard or electroplated fasteners can rust over time. This makes these nails a strong choice for long-term performance in roofing assemblies exposed to moisture and weather. For seaside or marine environments with higher salt exposure, Type 316 stainless steel is recommended.

What does the ring shank do compared to a smooth shank nail?

The annular-ring shank creates mechanical interlock with the wood fibers in the roof deck as the nail is driven in. This significantly increases withdrawal resistance - meaning the nail resists being pulled back out - compared to a smooth shank nail of the same length and gauge, resulting in a more secure fastener attachment over the life of the roof.
