Simpson Strong-Tie 16d x 3-1/2" 20-22 Degree Collated Ring-Shank Nail in Type 316 Stainless Steel is a professional-grade framing and structural fastener engineered for demanding applications where corrosion resistance is essential. The annular-ring shank delivers exceptional withdrawal resistance, making these full-round-head collated nails ideal for coastal construction, marine environments, and projects requiring long-term holding power. Manufactured in the United States from Type 316 stainless steel, these 10-gauge plastic-strip nails are compatible with many major manufacturers' pneumatic framing nailers, helping crews drive faster and work more efficiently on the job site.

Key Features

• Type 316 Stainless Steel material - provides superior corrosion resistance against saltwater, moisture, and harsh outdoor conditions, making these nails a proven choice for seaside and marine applications where standard galvanized fasteners fall short.
• Annular-ring (ring-shank) shank design - dramatically increases withdrawal resistance compared to smooth-shank nails, ensuring a more secure, long-lasting attachment in structural and framing applications.
• 20-22 degree plastic-strip collation - reduces driving force and speeds up installation, allowing pneumatic nailers to cycle quickly and keep pace on high-volume framing and decking projects.
• Full round head with checkered pattern - the checker head blends with wood grain, reduces sunlight glare, and accepts surface finishes, delivering a cleaner appearance on exposed installations.
• Diamond point tip - penetrates wood cleanly and accurately, minimizing splitting risk and improving placement precision during rapid pneumatic driving.
• 10 gauge, 0.131" shank diameter at 3-1/2" length (16d penny size) - provides the shank stiffness and fastener length required for typical framing connections and dimensional lumber applications.
• 9/32" head diameter - offers solid bearing surface for reliable fastener seating and load transfer in wood-to-wood connections.
• Compatible with many major pneumatic nailer brands - reduces the need to source brand-specific consumables, simplifying procurement across multi-tool job sites.

Why This Product

• Built for coastal and harsh-environment construction - Type 316 stainless steel is the go-to material for seaside applications where elevated chloride exposure and moisture would corrode standard carbon steel or lower-grade stainless fasteners over time.
• Maximizes holding power without extra hardware - the annular-ring shank increases withdrawal resistance mechanically, so the fastener itself does the heavy lifting without requiring additional connectors or adhesives to maintain a secure joint.
• Speeds up pneumatic framing workflows - plastic-strip collation at 20-22 degrees is engineered to reduce driving force and increase installation speed, meaning less fatigue and more nails driven per hour on large framing or decking projects.
• American-made quality with broad tool compatibility - produced in the United States and sized to work with many major manufacturers' pneumatic tools, reducing downtime spent sourcing compatible consumables on the job site.

Frequently Asked Questions

Why choose Type 316 stainless steel over other nail materials for outdoor or marine projects?

Type 316 stainless steel offers superior corrosion resistance compared to standard galvanized or lower-grade stainless fasteners, making it the recommended choice for seaside applications, marine environments, and any project exposed to saltwater, humidity, or harsh chemical conditions. The 316 alloy's composition provides long-term performance where other materials would degrade prematurely.

What is the benefit of an annular-ring shank compared to a smooth-shank nail?

The annular-ring (ring-shank) shank features circular ridges along the shank that grip the surrounding wood fibers and significantly increase withdrawal resistance. This means the fastener resists being pulled back out of the wood over time, providing a more secure and durable attachment - particularly important in structural framing, decking, and applications subject to dynamic or tensile loads.

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

These nails are compatible with many major manufacturers' pneumatic framing nailers that accept 20-22 degree plastic-strip collated full-round-head nails. Compatible brands include Bosch, Bostitch, DeWalt, Grip-Rite, and Hitachi, among others. For a full list of verified compatible tools and models, refer to the Tool Compatibility Matrix linked in the Downloads and Resources section below.

What does the checkered head pattern on these nails actually do?

The checkered pattern on the full round head serves three practical purposes: it blends with the natural wood grain for a less visually prominent fastener appearance, it reduces sunlight glare on exposed surfaces, and it accepts surface finishes such as paint or stain - useful when the nail head will be visible on finished work.
