The Simpson Strong-Bolt 2 Wedge Anchor in 316 Stainless Steel is a wedge-type expansion anchor engineered for demanding structural connections in both cracked and uncracked concrete. Every component in the assembly - anchor body, nut, washer, and clip - is manufactured from Type 316 Stainless Steel, delivering uniform, end-to-end corrosion protection suited to corrosive, moisture-prone, and chemically aggressive service environments. Code listed for seismic and high-wind condition applications, this 3/8 in. x 7 in. anchor is a dependable choice wherever load performance and long-term durability cannot be compromised.

Key Features

• Full Type 316 Stainless Steel Assembly - Every part, including the anchor body, nut, washer, and clip, is Type 316 Stainless Steel, so there are no mixed-metal weak points that could corrode prematurely in wet or chemically aggressive environments.
• Approved for Cracked and Uncracked Concrete - The Strong-Bolt 2 is code listed for both cracked and uncracked concrete installations, giving installers a single anchor solution that remains compliant across varied jobsite conditions.
• Dual Undercutting Embossments on the Clip - Each clip segment features dual undercutting embossments that enable secondary expansion if a crack forms and intersects the anchor location, helping maintain load-carrying capability even when the hole expands.
• Seismic and High-Wind Code Listing - Formal code listing for seismic zone structural connections and high-wind condition applications means this anchor meets the documentation requirements for critical, permit-driven work.
• 3/8 in. Drill Bit Diameter - The anchor installs with a standard 3/8 in. drill bit, streamlining tool selection and keeping installation straightforward on the jobsite.

Why This Product

• Uniform corrosion resistance throughout the entire assembly - Because the body, nut, washer, and clip are all Type 316 Stainless Steel, installers avoid the galvanic corrosion risk that occurs when mixed materials are used, making this anchor well suited to marine, coastal, chemical, and other moisture-prone settings.
• Versatile code-listed performance for structural applications - With listings covering cracked concrete, uncracked concrete, seismic zones, and high-wind conditions, this wedge anchor addresses a broad range of engineered connection requirements under a single model number.
• Built-in crack-response technology - The dual undercutting embossments on the clip allow the anchor to undergo secondary expansion if a concrete crack develops at the installation point, supporting continued load performance rather than relying solely on the initial set.
• Straightforward installation with common tooling - The 3/8 in. drill bit requirement and standard wedge-anchor installation process mean crews can work efficiently without specialized equipment, reducing installation time on both new construction and retrofit projects.
