Overview

The Simpson Strong-Tie Wedge-All Wedge Anchor (WA50812MG) is designed for heavy-duty fastening applications in solid concrete and grout-filled masonry. Supplied in a 25-piece box, this 1/2 in. x 8-1/2 in. galvanized wedge-style expansion anchor provides a reliable mechanical connection where building code approval for seismic and cracked/uncracked concrete is not required.

Anchor Type Wedge-style expansion anchor
Box Quantity 25 pieces

Technical Features

  • Wedge-style expansion mechanism: The anchor expands mechanically against the concrete substrate upon torque application, creating a secure load-bearing connection without adhesive.
  • Torque-set installation: Threaded studs are set by tightening the nut to a specified torque value, enabling consistent, verifiable installation on every anchor.
  • Galvanized finish: Provides corrosion resistance suitable for protected exterior and general construction environments.
  • 1/2 in. x 8-1/2 in. dimensions: Large diameter and extended length support deep embedment for increased holding strength in thick concrete sections.
  • 25-piece boxed quantity: Packaged for job-site efficiency, reducing handling time on projects with multiple anchor points.

Applications

  • Anchoring structural elements, equipment, and fixtures into solid concrete slabs and walls.
  • Fastening into grout-filled masonry where a mechanical expansion anchor is specified.
  • General construction installations where seismic design category or cracked-concrete code approval is not a project requirement.
  • Suitable for use in applications where consistent torque-controlled installation is required for quality assurance.
