The Simpson 3-1/4 in. 10 ga. Type 304 Stainless Steel 20 deg. - 22 deg. Plastic Strip Casing Head Ring-Shank Nail is built for professional-grade fastening of wood deck boards and siding to wood, delivering the corrosion resistance, holding power, and finished appearance that demanding outdoor installations require. Collated in a 20 deg. - 22 deg. plastic strip format, these 12d nails feed consistently and without obstruction through most major manufacturers' compatible pneumatic strip nailers, reducing driving force and increasing installation speed on the job site. The annular ring-shank shank, countersunk casing head, and brown painted finish work together to produce a secure, low-profile result that holds up over time without standing out against decking or siding surfaces.

Key Features

• Type 304 Stainless Steel construction - provides long-lasting corrosion resistance for exterior applications like deck boards and siding where moisture exposure is a constant concern.
• Annular ring-shank design - increases withdrawal resistance compared to a smooth shank, keeping fasteners securely anchored in wood even through seasonal movement and heavy loads.
• Countersunk casing head - sits flush or slightly below the surface for a clean, professional finish that does not interfere with the look of decking or siding.
• Brown painted finish with checkered head pattern - helps fastener heads blend with natural wood grain and common decking and siding colors, minimizing visual distraction at the fastener point.
• 20 deg. - 22 deg. plastic strip collation - ensures consistent, obstruction-free auto-feed in compatible pneumatic strip nailers, supporting faster and more efficient installation.
• 1,000-count package - provides enough quantity to carry through full deck or siding projects without frequent restocking interruptions.

Why This Product

• Purpose-built for deck and siding work - the combination of an annular ring-shank for superior withdrawal resistance and a countersunk casing head makes this nail specifically suited for fastening wood deck boards and attaching siding to wood framing, addressing the precise demands of those applications.
• Corrosion resistance without compromise - Type 304 Stainless Steel construction means these collated framing nails maintain their holding strength and appearance in the wet, high-humidity conditions that routinely degrade standard steel fasteners on exterior projects.
• A finish that disappears into the work - the brown painted, checkered-pattern casing head is engineered to blend with wood grain and common decking and siding tones, so the fastener reinforces the installation without drawing attention to itself.
• Made in the United States by a trusted fastener brand - Simpson backs these nails with the engineering standards and quality control the brand is known for, giving contractors and builders confidence in consistent performance across every nail in the package.
