The Simpson 16d Ring-Shank Connector Nail is a purpose-built fastener engineered to deliver full rated load values when used with stainless steel structural connectors. Constructed from Type 316 stainless steel with an annular ring shank, this connector nail provides exceptional withdrawal resistance and lasting corrosion protection in coastal, marine, high-humidity, and other demanding environments where long-term fastener integrity is critical.

Key Features

• Type 316 Stainless Steel Construction - delivers superior corrosion resistance in salt air, marine, and high-moisture environments where standard steel fasteners would degrade prematurely
• Annular Ring Shank - mechanically locks into wood fiber to maximize withdrawal resistance, ensuring connections maintain their rated load capacity over the life of the structure
• Purpose-Matched for Simpson Stainless Steel Connectors - using matching stainless nail material with stainless connectors is required to achieve full connector load ratings and prevent galvanic corrosion at the connection point
• ASTM F1667 Compliant - meets the recognized standard for metal hardware nails, supporting code-compliant installations where stainless ring-shank connector nails are specified
• Made in the United States - domestic production supports consistent quality control and reliable availability for professional fastening applications

Why This Product

• Corrosion resistance where it matters most - Type 316 stainless steel is specifically suited for coastal, waterfront, and high-humidity projects where fastener corrosion is a primary long-term concern, making these nails a dependable choice for exposed or treated-lumber applications
• Engineered for full connector performance - pairing these ring-shank nails with Simpson stainless steel structural connectors ensures the connection achieves its full rated load values, not a reduced or compromised capacity
• Annular ring shank for superior holding power - the ring shank profile resists pull-through and withdrawal forces that smooth-shank nails cannot match, adding a meaningful layer of structural reliability to every connection
• Meets recognized industry standards - ASTM F1667 compliance means these fasteners satisfy specification requirements on projects where material standards are called out by architects, engineers, or building codes

Frequently Asked Questions

What are the dimensions and specifications of the SSA16D nail?

The SSA16D is a 16d nail measuring 3-1/2 inches in length with a 0.162-inch shank diameter and a 0.34-inch full round head. It features an annular ring shank and meets ASTM F1667 standards for metal hardware nails.

Why must Type 316 stainless steel nails be used with stainless steel connectors?

Using Type 316 stainless steel nails with stainless steel connectors ensures the connection achieves its full rated load values and maintains long-term corrosion resistance. Pairing dissimilar metals can compromise both performance and corrosion protection, particularly in harsh or coastal environments where superior durability is required.

How does the ring-shank design improve performance compared to smooth-shank nails?

The annular ring shank dramatically increases withdrawal resistance compared to smooth-shank nails, which helps structural connectors achieve their full rated load values. This makes the SSA16D well-suited for demanding structural applications where holding power is critical.

How many nails are included in a 1 lb. package of SSA16D?

Each 1 lb. package contains approximately 44 nails, making it a practical option for targeted repairs or smaller connector installations where a full bulk quantity is not needed.
