The Simpson 3 in. Tan Ring-Shank Casing Head Nail 304 SS 20-22 deg. Plastic Strip Collated 1000-Pk is a 10d, 11-gauge collated fastener from Simpson built for pneumatic nailers and engineered for two of the most demanding outdoor fastening tasks: securing wood deck boards and attaching siding to wood. The annular ring-shank design and Type 304 stainless steel construction work together to deliver a corrosion-resistant, high-holding-power connection, while the tan painted casing head with a checker pattern lets nail heads blend naturally into decking and siding surfaces for a clean, finished look. Plastic strip collation at 20 deg. - 22 deg. provides consistent, obstruction-free auto-feed compatible with most major manufacturers' pneumatic tools, helping crews reduce driving force and move through high-volume work faster.

Key Features

• Annular ring-shank - increases withdrawal resistance so fasteners grip wood decking and siding material firmly and stay put over time, even under seasonal movement and load.
• Countersunk casing head - sits flush or slightly below the surface after driving, giving deck boards and siding a neat, professional appearance without proud nail heads.
• Tan painted finish with checker head pattern - helps nail heads blend with wood grain and common decking and siding tones, reducing the visual footprint of every fastener.
• Type 304 stainless steel material - provides long-lasting durability and corrosion resistance for outdoor applications where moisture, humidity, and weathering are ongoing concerns.
• 20 deg. - 22 deg. plastic strip collation - delivers consistent, obstruction-free auto-feed through most major manufacturers' pneumatic nailers, keeping installation smooth and efficient on the job.
• 1,000 nails per package - supplies enough fasteners to sustain high-volume decking or siding runs without frequent reordering interruptions.
• Made in the United States - produced domestically to Simpson quality standards for reliable, consistent performance across every nail in the package.

Why This Product

• Holds where it counts outdoors - the annular ring-shank geometry mechanically locks into wood fibers, delivering greater withdrawal resistance than a smooth-shank nail and making it well suited for deck boards and siding that experience wind uplift, foot traffic, and thermal cycling.
• Virtually disappears in the surface - the combination of a tan painted finish, a countersunk casing head profile, and a checker head pattern that mimics wood grain means nail heads blend into decking and siding rather than drawing the eye, a genuine aesthetic advantage on visible exterior surfaces.
• Built to resist corrosion over the long term - Type 304 stainless steel is a proven material choice for exterior wood fastening, resisting rust and staining in wet or coastal-adjacent environments where lesser finishes deteriorate and bleed stains onto finished surfaces.
• Compatible with the tools already on site - the 20 deg. - 22 deg. plastic strip collation format works with most major manufacturers' pneumatic finish and framing nailers, so crews do not need to swap tools or stock a separate nailer just for this application.
