Simpson 1-1/2" 15 deg. Wire Coil Ring Shank Roofing Nails in Type 304 Stainless Steel are purpose-built for high-speed pneumatic roofing installation where long-term corrosion resistance and superior holding strength are both required. Designed by Simpson Strong-Tie, these 4d annular-ring shank fasteners drive cleanly through asphalt shingles and synthetic slate roofing materials, combining the efficiency of wire-coil collation with the durability of 304 stainless steel construction. Whether you're re-roofing a residential structure or installing synthetic slate on a coastal property, these fasteners deliver consistent performance and secure attachment in demanding outdoor environments.

Key Features

• Type 304 Stainless Steel material - provides excellent corrosion resistance for long-term performance in outdoor roofing applications where exposure to moisture and weather is constant
• Annular-ring (ring) shank - increases withdrawal resistance compared to smooth-shank nails, creating a more secure attachment to OSB and plywood roof decks that resists backing out over time
• Full round head with 3/8" head diameter - delivers broad bearing surface against roofing materials, reducing the risk of pull-through and holding shingles firmly in place
• 15 deg. wire-coil collation - compatible with many major manufacturers' pneumatic coil roofing nailers, reducing reload interruptions and increasing installation speed on large roofing jobs
• Diamond point tip - enables clean, fast penetration through asphalt and synthetic slate roofing materials with less driving force required
• 11-gauge shank at 0.120" diameter - delivers the right balance of shank strength and compatibility with pneumatic coil nailer tools designed for roofing-grade fasteners
• Smooth head pattern - allows clean, flush driving without surface damage to roofing materials during pneumatic installation
• Made in the United States - manufactured domestically to consistent quality standards expected of Simpson Strong-Tie fastener products

Why This Product

• Built for fast-paced roofing work: The 15 deg. wire-coil format and pneumatic tool compatibility with many major brands means fewer coil changes and faster coverage across large roof decks - directly reducing labor time on asphalt and synthetic slate roofing projects.
• Corrosion resistance that lasts: Type 304 stainless steel construction stands up to moisture and the outdoor conditions inherent to roofing applications, helping maintain fastener integrity long after installation is complete.
• Holding power where it matters: The annular-ring shank significantly increases withdrawal resistance compared to smooth-shank alternatives, keeping roofing panels and shingles anchored securely to the deck even under wind uplift conditions.
• Sized and specified for roofing: At 1-1/2" length with a full round head and diamond point, this nail meets the dimensional and performance requirements for asphalt shingle and synthetic slate roofing fastening without over-penetrating or damaging the deck below.

Frequently Asked Questions

What pneumatic nailers are compatible with these 15 deg. wire-coil roofing nails?

These nails are compatible with many major manufacturers' pneumatic coil roofing nailers. The existing description notes compatibility with tools from Bosch (RN175), Bostitch (RN46), DeWalt (D51321), Grip-Rite (GRTCR175), Hitachi (NV45AB2, NV45AE), Makita (AN453), Max (CN445R, CN450R), Paslode (R175-C, CR175C), Porter Cable (RN175A), Ridgid (R175RND), and Senco (RoofPro 455XP). Always verify compatibility with your specific tool model before use.

Why is an annular-ring shank better for roofing applications than a smooth shank?

The annular-ring shank - also called a ring shank - features rings along the shank that grip the wood fibers of OSB or plywood roof decks as the nail is driven. This mechanical interlock significantly increases withdrawal resistance compared to a smooth shank, meaning the nail resists backing out over time even under the movement and stress that roofing materials experience with thermal expansion and wind uplift.

Is Type 304 stainless steel appropriate for all roofing environments?

Type 304 stainless steel provides strong corrosion resistance suited for most residential and commercial roofing applications, including asphalt shingle and synthetic slate installations. For seaside or highly corrosive coastal environments with direct saltwater exposure, Type 316 stainless steel is generally recommended for superior corrosion resistance. The 304 grade is a solid choice for inland and standard outdoor roofing conditions.

What roofing materials are these nails designed to fasten?

These 1-1/2" ring shank roofing nails are ideal for asphalt roofing applications and synthetic slate roofing installations. The diamond point, full round head, and annular-ring shank are specifically configured for fast driving and superior holding in these roofing material types, making them a reliable choice for both new construction and re-roofing projects.
