Simpson 15 deg. Wire Coil Ring-Shank Nail 2-1/4 in. x.092 in. 304 SS Sienna Painted is a professional-grade collated fastener from Simpson engineered for fast driving and superior holding power in wood siding installation, as well as finishing, millwork, and trim applications. The annular ring shank and diamond point work together to drive cleanly and grip firmly, while the Sienna painted finish helps nail heads blend with siding material for a clean, finished appearance. Compatible with many major manufacturers' pneumatic coil nailers, this 15 deg. wire coil nail is built to keep high-volume jobs moving without sacrificing long-term performance.

Key Features

• Checkered head pattern - blends with wood grain, reduces glare from sunlight, and accepts surface finishes for a cleaner look on finished work
• Sienna painted finish - helps nail heads blend with siding material so fasteners stay visually discreet after installation
• Annular ring shank - increases withdrawal resistance to provide a secure attachment that reduces cupping of siding boards over time
• Slender 13-gauge shank and diamond point - make driving easier with less effort and reduced risk of splitting, improving installation speed
• Type 304 stainless steel construction - provides high-level corrosion resistance, making these nails well suited for exterior applications exposed to moisture and the elements
• 15 deg. wire coil collation - compatible with many major manufacturers' pneumatic coil nailers to maximize jobsite efficiency
• Full round head design - delivers solid bearing surface and consistent seating for reliable fastener performance across siding and trim applications

Why This Product

• Corrosion resistance built for the long term - Type 304 stainless steel stands up to moisture and exterior exposure, protecting the integrity of wood siding installations for years without the rust concerns common to uncoated fasteners.
• Holding power that keeps siding flat - the annular ring shank increases withdrawal resistance and reduces cupping of siding boards, maintaining the appearance and structural integrity of the finished surface.
• A finish that disappears into the work - the Sienna painted color combined with a checkered head pattern lets nail heads blend naturally with siding material and wood grain, delivering a professional result without visible hardware distractions.
• Efficiency from coil to nail gun - the 15 deg. wire coil format, diamond point, and slender gauge combine to reduce driving force and increase installation speed, making this fastener a practical choice for demanding production siding and trim work.

Frequently Asked Questions

What type of stainless steel is used in the S13A225CCS nail, and why does it matter?

These nails are made from Type 304 stainless steel, which provides high-level corrosion resistance. This makes them well suited for exterior applications such as wood siding installation where exposure to moisture and the elements is a concern over the long term.

Why does the annular ring shank matter for siding applications?

The annular ring shank increases withdrawal resistance to provide a secure attachment that reduces cupping of siding boards. This enhanced holding power helps maintain the integrity and appearance of the siding over time compared to smooth-shank nails.

What pneumatic nailers are these wire coil nails compatible with?

The S13A225CCS is a 15 deg. wire coil nail compatible with many major manufacturers' pneumatic coil nailers. Always consult your specific tool's manual to confirm compatibility before use.

How does the Sienna painted finish benefit the finished installation?

The durable Sienna painted finish helps the nail heads blend with siding material, while the checker pattern on the heads blends with wood grain, reduces glare from sunlight, and accepts surface finishes - resulting in a cleaner, more professional appearance on the completed installation.
