Simpson Strong-Tie SCNR Ring-Shank Connector Nails in Type 316 Stainless Steel are purpose-engineered fasteners designed to achieve maximum load values when used with stainless-steel structural connectors. The annular-ring shank delivers dramatically greater withdrawal resistance compared to smooth-shank alternatives, locking securely into framing members to maintain connector performance under dynamic and sustained loads. Whether you are working in coastal, marine, or chemically aggressive environments, these 8-gauge, 3-1/2 in. nails are the right choice for full structural integrity in demanding conditions.

Key Features

• Type 316 Stainless Steel material - provides superior corrosion resistance in saltwater, marine, and chemically exposed environments where standard fasteners would degrade prematurely
• Annular-ring shank design - the ringed profile bites into wood fibers for exceptional withdrawal resistance, helping connectors achieve their full rated load values
• Full round head with smooth face - seats flush and evenly against connector plates, distributing load properly and ensuring a secure, professional installation
• 0.340 in. head diameter - sized to properly engage connector nail holes without overdriving, maintaining the structural integrity of the connection
• 0.162 in. shank diameter (8-gauge) - matches the nail hole geometry of Simpson Strong-Tie stainless-steel connectors for optimized fit and load transfer
• 3-1/2 in. length - provides sufficient penetration depth into framing members for secure engagement while remaining compatible with standard dimensional lumber thicknesses
• Head ID stamp for easy identification - allows inspectors and installers to quickly verify the correct fastener type is used, supporting code compliance on the job site
• Made in the United States - domestic manufacturing supports consistent quality control and reliable availability for professional construction projects

Why This Product

• Engineered specifically for stainless-steel connectors - Simpson Strong-Tie developed these nails as the optimum fastener for their own connector products, meaning the diameter, length, and shank profile are matched to achieve published load values rather than relying on a generic substitute
• The right fastener for harsh outdoor and coastal environments - Type 316 stainless steel is the appropriate material choice when using stainless-steel connectors in wet, salt-air, or corrosive conditions where other nail materials would compromise both the fastener and connector longevity
• Ring-shank profile maximizes withdrawal resistance - when connector load ratings depend on nail performance, the annular-ring shank holds significantly better than smooth-shank nails, helping the overall assembly meet its structural design intent
• Depth and gauge compatibility designed for economy - special lengths are selected to afford economy of purchase and installation, reducing waste and simplifying fastener selection on multi-connector projects

Frequently Asked Questions

Why must I use Type 316 stainless-steel nails with stainless-steel connectors?

Using Type 316 stainless-steel nails with stainless-steel connectors prevents galvanic corrosion that can occur when dissimilar metals contact each other in wet or coastal environments. Matching the nail material to the connector material also ensures that the published connector load values can be achieved, as the fastener is part of the engineered system.

What is the difference between an annular-ring shank and a smooth shank for connector nails?

An annular-ring shank has a series of ridges along the shank that interlock with wood fibers as the nail is driven, creating significantly greater withdrawal resistance than a smooth shank. For structural connectors, this increased holding power is critical - ring-shank nails allow connectors to reach their full rated load capacity, whereas smooth-shank alternatives may not meet the same performance thresholds.

What size connector nail hole do these nails fit?

These nails have a shank diameter of 0.162 in. and a full round head diameter of 0.340 in. They are designed to fit the nail hole geometry found in Simpson Strong-Tie stainless-steel connectors, ensuring proper load transfer and seating without overdriving or gap-fitting issues.

Are these nails compatible with hand nailing and pneumatic tools?

These SCNR ring-shank connector nails are sold as individual collation-free fasteners, making them suitable for hand nailing applications with Simpson Strong-Tie connectors. Always verify tool compatibility with the specific nail dimensions - 0.162 in. shank diameter, 0.340 in. head diameter, and 3-1/2 in. length - before use in any pneumatic nailer.
