The Simpson Strong-Bolt 2 3/4 in. x 12 in. Mechanically Galvanized Wedge Anchor is a heavy-duty wedge-type expansion anchor engineered by Simpson for high-load anchoring in exterior concrete and masonry applications. Built from mechanically galvanized carbon steel, this fully assembled anchor features dual undercutting embossments on each clip segment and is tested in uncracked concrete in accordance with AC193 and in uncracked masonry in accordance with AC01 - making it a dependable choice where structural integrity and corrosion resistance are equally critical.

Key Features

• Chamfered top designed to prevent mushrooming during installation - protects the anchor threads during driving, helping ensure a clean, reliable installation every time.
• Suitable for horizontal, vertical, and overhead applications - gives contractors and builders the flexibility to use a single anchor type across multiple installation orientations on the same job site.
• Standard (ANSI) fractional sizes - fits standard fixtures and installs with common drill bit and tool sizes, so no specialty tooling is required and workflow stays efficient.
• Tested per ACI355.2 and AC193 - third-party testing in recognized standards gives engineers and inspectors the documentation needed for code-compliant structural projects.
• Mechanically galvanized carbon steel construction - provides enhanced corrosion resistance suited for exterior environments where zinc-electroplated finishes may fall short.
• Installs with a 3/4 in. drill bit and 1-1/8 in. wrench - straightforward tooling requirements mean faster setup and less time sourcing equipment on the job.

Why This Product

• Built for demanding exterior anchoring - the mechanically galvanized finish delivers a higher level of corrosion protection than standard electroplated anchors, making this wedge anchor a practical solution for exposed and outdoor concrete or masonry installations.
• Dual undercutting embossments on each clip segment - this design detail, shared with the zinc-electroplated Strong-Bolt 2, is engineered to improve load resistance and anchoring performance in structural applications.
• Multi-orientation versatility from one anchor - tested and approved for horizontal, vertical, and overhead use, this anchor reduces the need to stock multiple product types for varied fastening tasks on a single project.
• Fully assembled and ready to install - arriving pre-assembled with all components in place, this anchor simplifies the installation process and helps keep projects moving without extra prep steps on site.
