The Simpson Strong-Bolt 2 Wedge Anchor in 3/4 in. x 7 in., Type 316 Stainless Steel is a high-performance wedge-type expansion anchor engineered for demanding concrete anchoring applications where long-lasting corrosion resistance is essential. Every component - anchor body, nut, washer, and clip - is constructed from Type 316 stainless steel, eliminating the risk of galvanic corrosion between dissimilar metals and ensuring consistent performance in a wide variety of service environments. Code listed for use in both cracked and uncracked concrete, this anchor is purpose-built to deliver reliable, compliant results in seismic and high-wind conditions alike.

Key Features

• All-Type-316 stainless steel construction throughout every component - the anchor body, nut, washer, and clip are all the same material, preventing galvanic corrosion and providing long-lasting resistance across demanding service environments.
• Code listed for cracked and uncracked concrete - gives contractors and engineers a single, versatile anchor solution that satisfies code requirements across a broad range of structural applications without the need for separate products.
• Dual undercutting embossments on each clip segment - allow for secondary expansion if a crack forms and intersects the anchor location, helping maintain load capacity even as the hole expands and making this anchor a dependable choice in seismic zones.
• Rated for seismic and high-wind applications - qualifies this wedge anchor for use in high-performance structural installations where other standard anchors may not meet code, reducing specification risk on critical projects.
• 3/4 in. drill bit diameter matches nominal anchor size - simplifies installation by requiring no special tooling or upsized hole preparation, ensuring proper fit and reliable expansion performance on the job site.

Why This Product

• Full material consistency from clip to body - because every component is Type 316 stainless steel, there is no weak link in the corrosion resistance chain, making this anchor well suited for coastal, industrial, or otherwise corrosive environments where mixed-metal anchors would be a liability.
• One anchor, two concrete conditions - the Strong-Bolt 2 is code listed for both cracked and uncracked concrete, so specifiers and installers can rely on a single product SKU across varying substrate conditions rather than stocking and managing multiple anchor types.
• Built-in redundancy for seismic and dynamic load scenarios - the dual undercutting embossments provide secondary expansion if cracking occurs at the anchor point, giving structural professionals added confidence that load capacity is maintained even after a seismic event.
• Straightforward installation with a standard 3/4 in. drill bit - the anchor diameter and required hole size match directly, streamlining field preparation and reducing the chance of installation error on time-sensitive concrete anchoring projects.

Frequently Asked Questions

Is the Strong-Bolt 2 suitable for use in cracked concrete?

Yes. The Strong-Bolt 2 is code listed for both cracked and uncracked concrete applications. Its dual undercutting embossments on each clip segment allow for secondary expansion if a crack forms and intersects the anchor location, helping maintain load capacity even as the hole expands.

Why is Type 316 stainless steel used for all components?

Type 316 stainless steel is used for the anchor body, nut, washer, and clip to provide long-lasting corrosion resistance across a wide variety of service environments. Using the same material throughout ensures consistent performance without the risk of galvanic corrosion between dissimilar metals.

What size hole should be drilled to install this anchor?

A 3/4 in. diameter drill bit should be used when installing this anchor, matching the anchor's nominal diameter for proper fit and expansion performance.

Can this anchor be used in seismic or high-wind applications?

Yes. The Strong-Bolt 2 wedge anchor is an optimal choice for high-performance anchoring even in seismic and high-wind conditions, and it is code listed for these demanding environments.
