The Simpson 15 deg. Wire Coil Ring-Shank Nail, 2-1/2 in. x.092 in., 304 SS White Painted Full Round Head is a collated fastener from Simpson engineered to combine fast, efficient installation with the long-term durability of stainless steel. Designed for asphalt and synthetic slate roofing applications as well as wood siding work, this nail pairs a slender 13-gauge shank and diamond point for effortless driving with an annular ring shank for superior holding power. The white painted finish and checkered head pattern help nail heads blend naturally with siding material, while Type 304 stainless steel construction provides high-level corrosion resistance for lasting performance in demanding exterior environments. Collated at 15 deg. wire-coil format, these nails are compatible with many major manufacturers' pneumatic tools for streamlined, high-speed fastening on the job.

Key Features

• Type 304 stainless steel construction - delivers high-level corrosion resistance, keeping fasteners secure and structurally sound through long-term moisture and weather exposure in roofing and siding applications
• Annular ring shank design - increases withdrawal resistance to provide a secure attachment that reduces cupping of siding boards, offering superior holding power over smooth-shank alternatives
• White painted finish - helps nail heads blend with siding material for a cleaner, less noticeable appearance on finished surfaces
• Checkered head pattern - blends with wood grain, reduces glare from sunlight, and accepts surface finishes for a discreet, professional result
• Slender 13-gauge shank and diamond point - allow easier driving with reduced splitting risk, speeding up installation without sacrificing fastening integrity
• 15 deg. wire-coil collation - compatible with many major manufacturers' pneumatic tools, reducing driving force and increasing installation speed on large roofing and siding projects

Why This Product

• Built for exterior durability - Type 304 stainless steel provides high-level corrosion resistance, making these ring-shank nails a reliable long-term choice for asphalt roofing, synthetic slate, and wood siding applications where standard fasteners would degrade over time
• Holds tighter, longer - the annular ring shank design increases withdrawal resistance and helps prevent siding board cupping, providing a more secure attachment than smooth-shank nails in demanding fastening conditions
• Designed to disappear into the finish - the white painted heads and checkered pattern work together to minimize visual impact on siding and roofing material, delivering a cleaner result without additional touch-up work
• Fast and tool-friendly - 15 deg. wire-coil collation paired with a slender gauge and diamond point means easier driving, faster completion, and compatibility with many major pneumatic nailers already on the job site
