Simpson 16d x 3-1/2" 20 deg.-22 deg. Collated Ring-Shank Nail in Type 304 Stainless Steel is a heavy-duty fastener engineered for projects that demand superior holding power and lasting corrosion resistance. Manufactured by Simpson Strong-Tie, this 10-gauge, full-round-head nail features an annular-ring shank that dramatically increases withdrawal resistance compared to smooth-shank alternatives, making it a reliable choice for structural framing, decking, and other demanding wood construction applications. The plastic-strip collation at a 20 deg.-22 deg. angle works seamlessly with many major pneumatic nailers, helping crews drive more fasteners in less time while maintaining consistent, professional results.

Key Features

• Annular-Ring (Ring-Shank) Shank - increases withdrawal resistance so nails grip wood fibers more aggressively than smooth-shank designs, providing a more secure and lasting attachment in structural and load-bearing connections.
• Type 304 Stainless Steel Material and Finish - delivers strong corrosion resistance in outdoor, humid, and treated-lumber environments where carbon steel fasteners would rust and degrade over time.
• 10 Gauge / 0.131" Shank Diameter - provides the shank thickness needed for heavy framing and structural applications, balancing driving ease with robust holding strength.
• 16d Penny Size / 3-1/2" Length - the standard framing nail length for full-depth penetration into dimensional lumber, making it suitable for wall framing, floor systems, and similar structural tasks.
• Full Round Head with Checkered (Checker) Pattern - the 9/32" diameter full round head maximizes bearing surface for superior holding, while the checker pattern blends with wood grain, reduces sunlight glare, and accepts surface finishes for a clean appearance.
• Diamond Point Tip - pierces wood cleanly and consistently, reducing splitting risk in tight-grain or dense lumber.
• 20 deg.-22 deg. Plastic-Strip Collation - compatible with many major manufacturers' pneumatic framing nailers, reducing driving force requirements and increasing installation speed on the job site.
• Made in the United States - domestic manufacturing supports consistent quality standards and reliable availability for professional contractors and builders.

Why This Product

• Built for corrosion-prone environments: The Type 304 stainless steel construction resists rust and degradation in damp conditions, coastal-adjacent locations, and applications involving treated lumber - situations where standard steel fasteners can fail prematurely.
• Engineered for maximum grip: The annular-ring (ring-shank) shank design mechanically interlocks with wood fibers, making it the right choice when withdrawal resistance matters most - such as decking, roofing, and structural sheathing attachments.
• Speeds up framing work without sacrificing quality: Plastic-strip collation at the 20 deg.-22 deg. angle reduces driving force and feeds consistently through compatible pneumatic nailers, so installers maintain productivity on high-volume framing jobs without interruptions.
• Versatile compatibility across job sites: The 20 deg.-22 deg. collation angle is widely accepted by many major pneumatic nailer brands, meaning this nail can integrate into existing tool setups without requiring specialized equipment.

Frequently Asked Questions

What type of pneumatic nailer is compatible with this collated nail?

This nail uses 20 deg.-22 deg. plastic-strip collation, which is compatible with many major manufacturers' pneumatic framing nailers. For a detailed list of specific tool models and compatibility, refer to the Tool Compatibility Matrix available in the Downloads and Resources section below.

Why choose a ring-shank nail over a smooth-shank nail for structural applications?

The annular-ring shank on this nail mechanically interacts with wood fibers along the length of the shank, increasing withdrawal resistance compared to smooth-shank nails. This makes ring-shank fasteners especially well-suited for structural connections, decking, sheathing, and other applications where nails must resist being pulled back out under load or movement.

Is Type 304 stainless steel suitable for outdoor and treated-lumber use?

Type 304 stainless steel provides corrosion resistance that makes it appropriate for outdoor environments and applications involving exposure to moisture. If you require even greater corrosion resistance - such as in seaside or highly corrosive environments - a Type 316 stainless steel option may be considered for those conditions.

What does the checkered head pattern on this nail do?

The checker pattern on the full-round head serves three practical purposes: it blends with the natural texture of wood grain for a less obtrusive appearance, it reduces sunlight glare on exposed nail heads, and it accepts surface finishes such as paint or stain for a consistent look on finished surfaces.
