Simpson 6d x 2" 20 deg.-22 deg. Collated Ring-Shank Nail in 304 Stainless Steel (12 Gauge) by Simpson Strong-Tie is a professional-grade fastener engineered for high-speed pneumatic nail gun applications where corrosion resistance and superior holding power are essential. The annular-ring shank bites into wood fibers for dramatically increased withdrawal resistance compared to smooth-shank alternatives, making these nails a reliable choice for framing, decking, and other structural or finish applications where a secure, long-lasting attachment matters. Manufactured from Type 304 stainless steel and collated in a 20 deg.-22 deg. plastic strip, they deliver fast, consistent feeding in a wide range of pneumatic tools from major manufacturers.

Key Features

• Type 304 Stainless Steel material - provides excellent corrosion resistance for outdoor, coastal, and high-moisture environments where standard steel nails would rust and stain surrounding wood surfaces.
• Annular-ring shank (ring shank) - the grooved shank locks into wood fibers to significantly increase withdrawal resistance, reducing the chance of fasteners backing out over time under load or seasonal wood movement.
• 20 deg.-22 deg. plastic-strip collation - compatible with many major pneumatic framing nailer brands, enabling faster installation, reduced hand fatigue, and a higher nails-per-strip count compared to wire-weld configurations.
• Full round head with checkered pattern - the 9/32" diameter full round head provides maximum bearing surface and code-compliant performance, while the checker pattern blends with wood grain, reduces sunlight glare, and accepts surface finishes for a cleaner appearance.
• Diamond point tip - the precision-ground point drives cleanly into wood with reduced splitting and less driving force required, speeding up installation and protecting workpiece integrity.
• 12 gauge wire diameter with 0.113" shank - a robust cross-section that maintains shear strength and structural integrity in demanding framing and construction applications.
• Made in the United States - consistent quality control throughout manufacturing, ensuring dimensional accuracy and reliable performance nail after nail.

Why This Product

• Built for corrosive environments: Type 304 stainless steel resists rust, oxidation, and staining - a critical advantage when fastening in wet conditions, near water, or in contact with treated lumber that can corrode standard steel fasteners.
• Superior holding power vs. smooth-shank nails: the annular-ring shank dramatically increases withdrawal resistance, so these nails stay put even under cyclic loading, vibration, or repeated expansion and contraction of wood - ideal where structural integrity cannot be compromised.
• Broad tool compatibility: the 20 deg.-22 deg. plastic-strip format is accepted by pneumatic framing nailers from many leading manufacturers, reducing downtime spent searching for brand-specific fasteners on the job site.
• Finish-friendly head design: the checkered head pattern blends with wood grain and accepts paints, stains, and other surface finishes, making these nails suitable not only for structural framing but also for visible finish work where aesthetics matter.

Frequently Asked Questions

What types of pneumatic nailers are compatible with these 20 deg.-22 deg. plastic-strip collated nails?

These nails are collated at a 20 deg.-22 deg. angle in a plastic-strip format, which is compatible with many major manufacturers' pneumatic framing nailers. For a complete list of verified compatible tools and models, refer to the Tool Compatibility Matrix linked in the Downloads section below.

Why choose Type 304 stainless steel over standard galvanized nails?

Type 304 stainless steel offers superior, long-term corrosion resistance compared to typical galvanized coatings, making these nails a strong choice for applications in moist, outdoor, or chemically challenging environments where galvanized nails may eventually rust or cause surface staining. For seaside or highly aggressive salt-air environments, a Type 316 stainless steel option is also available.

What is an annular-ring shank, and how does it differ from a smooth shank?

An annular-ring shank - also called a ring shank - features circumferential grooves along the shank that mechanically interlock with surrounding wood fibers once driven. This design increases withdrawal resistance substantially compared to a smooth-shank nail, making ring-shank nails the preferred choice wherever fasteners must resist being pulled back out under load, vibration, or wood movement.

What does the checkered head pattern on these nails offer beyond appearance?

The checkered pattern on the full round head serves three practical purposes: it blends with the natural texture of wood grain for a cleaner look, reduces sunlight glare on driven nail heads, and provides a surface that accepts paints, stains, and other finishes - useful when nails are driven in areas that will later be coated.
