Simpson Strong-Tie 10d 0.148" x 3" SCNR Annular Ring-Shank Connector Nail in Type 316 Stainless Steel is engineered specifically for use with stainless-steel structural connectors where maximum withdrawal resistance and long-term corrosion protection are required. Developed by Simpson Strong-Tie as the optimum fastener for their connector product line, this full round head ring-shank nail delivers the holding power and material compatibility needed to achieve full rated load values in demanding structural applications - including coastal, marine-adjacent, and chemically exposed environments where standard fasteners fall short.

Key Features

• Type 316 Stainless Steel material - provides superior corrosion resistance compared to standard steel or lower-grade stainless, making these nails well-suited for harsh outdoor, high-humidity, and saltwater-adjacent environments where connector integrity must be maintained over time.
• Annular ring-shank (ring-shank) design - the annular rings along the shank grip the wood fibers mechanically, dramatically increasing withdrawal resistance compared to a smooth-shank nail and helping connectors achieve their maximum rated load values.
• Full round head with smooth head pattern - seats cleanly and completely against connector flanges to distribute load evenly, ensuring proper bearing contact for structural integrity.
• 0.148" shank diameter (9 gauge) x 3" length - dimensioned to provide depth compatibility with standard framing members, reducing waste and simplifying installation when fastening Simpson Strong-Tie connectors.
• 0.310" head diameter - sized to bear correctly against connector nail hole patterns, preventing pull-through and maintaining the connection under load.
• Made in the United States - manufactured domestically to Simpson Strong-Tie quality standards, ensuring consistent dimensional tolerances and material specification compliance.

Why This Product

• When pairing with stainless-steel connectors, using a matching Type 316 stainless nail eliminates galvanic incompatibility between fastener and connector - preserving both structural load capacity and long-term corrosion resistance at the joint.
• The annular ring-shank geometry is specifically identified by Simpson Strong-Tie as the best choice for achieving maximum load values in stainless-steel connectors - meaning you get full published connector performance rather than a reduced value that can result from using smooth-shank alternatives.
• Simpson Strong-Tie engineered these nails alongside their connector products, so the shank diameter, length, and head dimensions are optimized for economy of purchase and installation - no guessing about compatibility with connector nail hole sizes or framing depth.
• For applications in coastal zones, marine structures, or other corrosive environments where pressure-treated lumber and stainless hardware are specified together, Type 316 stainless provides the material match required to meet both performance and corrosion-resistance expectations.

Frequently Asked Questions

Why is a ring-shank nail recommended over a smooth-shank nail for Simpson Strong-Tie connectors?

The annular ring-shank profile mechanically locks into wood fibers, providing significantly higher withdrawal resistance than a smooth shank. Simpson Strong-Tie identifies SCNR ring-shank connector nails as the best choice for achieving maximum load values in stainless-steel connectors - meaning smooth-shank nails of the same diameter may not allow the connector to reach its published rated capacity.

What makes Type 316 stainless steel the right material choice for stainless connector applications?

Type 316 stainless steel offers strong resistance to corrosion in harsh and chemically active environments. When a stainless-steel connector is specified - often for coastal, marine-adjacent, or other corrosive conditions - using a matching Type 316 stainless nail prevents galvanic incompatibility between the fastener and the connector, preserving both the structural connection and the corrosion-resistance performance of the assembly.

What does the 0.148" shank diameter and 3" length mean for installation with standard framing?

The 0.148" (9 gauge) shank diameter is sized to fit the nail hole patterns in compatible Simpson Strong-Tie connectors, and the 3" length is dimensioned for depth compatibility with standard framing members. Simpson Strong-Tie developed these specific dimensions to afford economy of installation and ensure the nail engages the framing member adequately without over-penetrating or under-penetrating.

What head type and diameter do these connector nails use, and why does it matter?

These nails feature a full round head with a smooth head pattern and a 0.310" head diameter. The full round head is designed to seat completely and evenly against the surface of a connector flange, distributing the load across the head bearing area. Proper head bearing against the connector is critical to achieving the connector's full rated load - an undersized or improperly seated head can reduce effective load transfer at the joint.
