The Simpson Strong-Bolt 2 3/4 in. x 6-1/4 in. Mechanically Galvanized Wedge Anchor is a heavy-duty wedge-type expansion anchor built for high-load-resisting applications in both concrete and masonry. Constructed from mechanically galvanized carbon steel, this anchor is engineered specifically for exterior environments where corrosion resistance is critical. Dual undercutting embossments on each clip segment deliver the same proven holding performance as the zinc-electroplated Strong-Bolt 2 version, and the anchor is tested in uncracked concrete per AC193 and in uncracked masonry per AC01 - giving engineers and installers a dependable, code-referenced solution for demanding structural connections.

Key Features

• Mechanically galvanized carbon steel construction - provides enhanced corrosion resistance for reliable long-term performance in exterior and exposed environments
• Dual undercutting embossments on each clip segment - the same design as the zinc-electroplated Strong-Bolt 2, delivering high load capacity and consistent expansion performance
• Chamfered top - prevents mushrooming during installation, protecting threads and making nut seating straightforward
• Suitable for horizontal, vertical, and overhead applications - gives installers flexibility across a wide range of concrete and masonry anchoring orientations
• Standard ANSI fractional sizing - fits standard fixtures and installs with common tool sizes, including a 3/4 in. drill bit and 1-1/8 in. wrench, reducing the need for specialized equipment
• Tested per ACI355.2 and AC193 (uncracked concrete) and AC01 (uncracked masonry) - provides verifiable, standards-backed performance data to support engineering specifications and project approvals

Why This Product

• Exterior-rated corrosion protection - the mechanically galvanized finish on the anchor body makes this wedge anchor a dependable choice for outdoor structural anchoring where a standard zinc-electroplated finish would be insufficient
• Versatile installation orientations - approved for horizontal, vertical, and overhead use in both concrete and masonry, so a single anchor covers the full range of common structural attachment scenarios on a job site
• Standards-tested high-load performance - with testing conducted per AC193 and AC01 in uncracked substrates, this anchor supports engineering sign-off and meets the documentation requirements of commercial and structural projects
• Tool-compatible sizing - ANSI fractional dimensions mean installers work with the same 3/4 in. drill bit and standard wrench sizes already on hand, keeping installation straightforward and efficient
