The Simpson 8d Ring-Shank Connector Nail 0.131" x 2-1/2" 316 Stainless is a structural fastener engineered for use with stainless-steel connectors where corrosion resistance and full rated load performance are non-negotiable. Built by Simpson from Type 316 stainless steel, this annular-ring shank nail is the right choice for connector installations in demanding or corrosive environments where long-term holding strength is critical.

Key Features

• Type 316 Stainless Steel construction - provides robust corrosion resistance, keeping connections protected and structurally sound in harsh or moisture-exposed conditions
• Annular-ring shank design - dramatically increases withdrawal resistance compared to smooth-shank nails, so connections maintain their holding strength under load over time
• Full round head with smooth head pattern - seats flush and consistently against connector flanges, helping ensure proper load transfer at every connection point
• ASTM F1667 compliant - meets the standard specification for driven fasteners and metal hardware nails, supporting code-compliant structural installations
• 0.131" shank diameter, 2-1/2 in. length (8d) - sized specifically for use with stainless-steel Simpson connectors to achieve full published load values
• Sold by the pound - approximately 94 nails per pound, making it straightforward to estimate quantities needed for a given job

Why This Product

• Matched for stainless-steel connector performance - using a Type 316 stainless ring-shank nail with stainless-steel connectors is essential to achieving the rated load values those connectors are designed to deliver, eliminating a common source of under-performance in structural assemblies
• Superior withdrawal resistance where it matters most - the annular-ring shank provides a mechanical grip that smooth-shank nails simply cannot match, making these connectors a dependable choice for structural applications where load-bearing integrity is critical
• Built for corrosive environments - Type 316 stainless steel offers strong resistance to the elements, making these nails well-suited for coastal, marine, and other high-moisture applications where lesser fasteners would degrade
• Trusted brand, domestic production - manufactured by Simpson, a name professionals rely on for structural fasteners, these nails are made in the United States
