Product Description
The Simpson 12d x 3-1/4 in. 20-22 Deg. Plastic Strip Ring-Shank Casing Head Nail in Type 304 Stainless Steel is a collated fastening solution engineered for professional-grade installation of wood deck boards and siding to wood. Designed for use with pneumatic nailers, this ring-shank nail combines a countersunk casing head, gray painted finish, and annular ring shank to deliver a secure, clean result in demanding outdoor applications. The 20 deg. - 22 deg. plastic strip collation ensures consistent, obstruction-free auto-feed, helping reduce driving force and increase installation speed on the job site.
Key Features
- Annular ring-shank design - increases withdrawal resistance so fasteners hold firmly in wood deck boards and siding over time, even under repeated stress and seasonal movement.
- Countersunk casing head - sits flush or just below the surface for a clean, professional finish on decking and siding without raised nail heads interfering with trim or cladding.
- Gray painted finish with checkered head pattern - the durable color coating and checker pattern help nail heads blend with wood grain and siding material, minimizing visual impact after installation.
- Type 304 stainless steel construction - provides exceptional corrosion resistance for long-lasting performance in outdoor environments where moisture, salt, and the elements are a concern.
- 20 deg. - 22 deg. plastic strip collation - compatible with most major manufacturers' pneumatic nailers, enabling fast, reliable auto-feed and reducing downtime during high-volume fastening work.
- 1,000 nails per package - a high-quantity pack keeps large decking and siding projects moving without frequent restocking interruptions.
Why This Product
- Purpose-built for decking and siding - specifically designed for fastening wood deck boards and attaching siding to wood, so the head profile, shank geometry, and finish are all matched to these real-world applications rather than being a generic fastener adapted to them.
- Corrosion resistance you can count on outdoors - Type 304 stainless steel delivers proven durability in exterior conditions, making these nails a sound long-term choice for projects exposed to moisture and weathering year after year.
- A finish that works with the material, not against it - the gray painted casing head and checkered pattern are engineered to blend with decking and siding surfaces, so the completed installation looks intentional and professional rather than fastener-forward.
- Collation designed for speed and consistency - the plastic strip format at 20 deg. - 22 deg. feeds smoothly through compatible pneumatic tools, keeping installation moving efficiently on larger jobs where driving force and feed reliability directly affect productivity.

Frequently Asked Questions
What pneumatic nailers are compatible with these collated nails?
These nails feature a 20 deg. - 22 deg. plastic strip collation angle, which is compatible with most major manufacturers' pneumatic nailers that accept that collation range. The plastic strip design ensures consistent, obstruction-free auto-feed during use.
What are these nails made of, and are they suitable for outdoor use?
These nails are made from Type 304 stainless steel, which provides exceptional corrosion resistance and long-lasting durability. This makes them well-suited for demanding outdoor applications such as fastening wood deck boards and siding to wood.
What shank type do these nails have, and why does it matter?
These nails feature an annular ring shank (also called a ring shank), which increases withdrawal resistance compared to a smooth-shank nail. This provides a more secure, lasting attachment - particularly important in decking and siding applications where long-term holding power is essential.
What do the head style and gray finish offer for finished installations?
These nails have a countersunk casing head with a 1/4 in. head diameter and a gray painted finish. The durable painted finish helps the heads blend with decking and siding material, and a checker pattern on the heads blends naturally with wood grain for a clean, discreet appearance in the finished installation.
