Simpson 2 1/4" Full Round Head Ring-Shank Plastic Coil Nail by Simpson is a purpose-built fastener designed for use in pneumatic coil nailers, delivering reliable holding power in wood framing, decking, and trim applications. The annular ring shank provides significantly greater withdrawal resistance than a smooth-shank nail, making it a dependable choice wherever a secure, lasting connection is required. Crafted in the United States, this inserted plastic coil nail combines a low-profile checker-patterned head with a ring-shank design to meet the demands of professional contractors and serious DIYers alike.

Key Features

• Checker pattern on head - blends with natural wood grain and reduces sunlight glare, so finished surfaces look clean and accept stains, paints, and other surface finishes without visible nail-head interference.
• Annular ring shank - increases withdrawal resistance compared to smooth-shank nails, providing a more secure attachment that resists loosening over time due to wood movement, vibration, or seasonal expansion and contraction.
• Full round head design - delivers maximum bearing surface against the wood, distributing load more effectively for stronger holding in structural and general fastening applications.
• 0 deg. plastic coil collation - compatible with a range of professional-grade pneumatic coil nailers, allowing high-volume fastening with consistent feed and minimal jams for faster job-site productivity.
• Available in Type 304 stainless steel and aluminum - offering corrosion resistance suitable for outdoor, coastal, and moisture-prone environments where standard fasteners would degrade.

Why This Product

• The ring-shank profile provides superior grip compared to smooth nails, making these fasteners well suited for applications like deck boards, siding, and framing where pull-through or pull-out failure would be a concern.
• The checker-patterned full round head is engineered to blend into wood surfaces and accept surface finishes, reducing the need for touch-up work and delivering a cleaner, more professional result on visible surfaces.
• Designed for 0 deg. plastic coil collation, these nails are compatible with multiple professional pneumatic nailer brands, making them a practical choice for contractors who already own compatible tools.
• Made in the United States, this nail offers consistent dimensional quality and materials that meet the standards professional fastening applications demand.

Frequently Asked Questions

What pneumatic nailers are compatible with these 0 deg. plastic coil nails?

These nails are compatible with several professional-grade coil nailers, including the Duo-Fast models KDN50, RCN60, RCN70, CNP-60Y, and CNP-65Y, as well as the DF225C and the Spotnails model QCND65. Always confirm compatibility with your specific tool model before use.

Why choose a ring-shank nail over a smooth-shank nail for my project?

The annular ring shank increases withdrawal resistance, meaning the nail resists being pulled back out of the wood more effectively than a smooth-shank nail. This is especially valuable in applications subject to wood movement, vibration, or repeated stress - such as decking, siding, and framing.

Will the head of this nail show through surface finishes or stains?

The checker pattern on the head is specifically designed to blend with natural wood grain, reduce glare from sunlight, and accept surface finishes such as stains and paints. This makes it a practical choice for visible surfaces where a clean finished appearance matters.

What material options are available for this nail?

This nail is available in Type 304 stainless steel and aluminum, both of which offer corrosion resistance suited to outdoor, moisture-prone, or coastal environments where standard carbon steel fasteners might corrode or stain the surrounding wood.
