Simpson 6d x 2" 20-22 Degree Collated Ring-Shank Nail in 316 Stainless Steel by Simpson Strong-Tie is a 12-gauge, full-round-head fastener built for wood-to-wood fastening and framing applications where superior corrosion resistance is essential. The annular-ring shank bites into wood fibers to dramatically increase withdrawal resistance compared to smooth-shank nails, keeping connections tight even under load, vibration, or moisture exposure. Whether you're framing near the coast or working in chemically demanding environments, this Type 316 stainless steel nail delivers long-term holding power and lasting protection against corrosion.

Key Features

• Type 316 stainless steel material - resists saltwater, chemicals, and harsh outdoor environments, making this nail the right choice for seaside construction and applications where corrosion would compromise structural integrity.
• Annular-ring (ring-shank) shank design - the rings grip surrounding wood fibers and increase withdrawal resistance, providing a more secure attachment than smooth-shank alternatives in framing and wood-to-wood connections.
• 20-22 degree plastic-strip collation - compatible with many major manufacturers' pneumatic framing nailers, so you can drive nails faster and with less manual effort, boosting installation speed on the job site.
• Full round head with checkered pattern - the checker head pattern blends with wood grain, reduces sunlight glare, and accepts surface finishes, delivering a clean, professional appearance after installation.
• Diamond point tip - pierces wood cleanly and consistently, reducing splitting risk and helping keep the nail on target with each drive.
• 12-gauge, 0.113" shank diameter with 9/32" head diameter - provides the right balance of shank strength and bearing surface for secure load transfer in framing connections.
• Made in the United States - manufactured domestically to consistent quality standards.

Why This Product

• If your framing or wood-to-wood fastening project is in a coastal, waterfront, or chemically aggressive setting, the Type 316 stainless steel finish provides a higher level of corrosion resistance than standard galvanized options, keeping connections sound over time.
• The annular-ring shank solves the problem of nails backing out over time - rings mechanically lock into wood fibers so connections stay tight, even where vibration, seasonal movement, or heavy loads are factors.
• The 20-22 degree plastic-strip format means these nails feed reliably in many major-brand pneumatic framing tools, reducing hand-nailing fatigue and keeping installation moving efficiently on larger framing jobs.
• The checkered full-round head is designed to accept surface finishes and minimize visible glare, making these nails a practical choice when the final appearance of the wood surface matters after fastening.

Frequently Asked Questions

What makes the annular-ring shank different from a smooth-shank nail?

The annular-ring shank features rings along the shank that grip surrounding wood fibers as the nail is driven. This significantly increases withdrawal resistance compared to smooth-shank nails, meaning the fastener is far less likely to back out over time - especially important in framing and structural wood-to-wood connections subject to load or movement.

Why is Type 316 stainless steel used instead of standard stainless or galvanized finishes?

Type 316 stainless steel contains molybdenum, which gives it enhanced resistance to chlorides - such as salt air and seawater - and certain chemicals compared to other stainless grades. This makes it the preferred material for seaside applications and environments where superior corrosion resistance is required for long-term connection integrity.

What pneumatic nailers are compatible with these 20-22 degree plastic-strip collated nails?

These nails are compatible with many major manufacturers' pneumatic framing tools that accept 20-22 degree plastic-strip collation. For a full list of verified compatible tool models, refer to the Tool Compatibility Matrix available in the Downloads and Resources section below, or contact us and a sales professional will assist with fastener selection.

What does the checkered head pattern on these nails do?

The checkered pattern on the full-round head is designed to blend visually with wood grain, reduce sunlight glare on the exposed nail head, and accept surface finishes applied after installation. This makes the nails a practical choice when the finished appearance of the wood surface is a consideration.
