What is the primary purpose of a wedge anchor?

The primary purpose of a wedge anchor is to fasten materials to concrete. Wedge anchors are used in construction and industrial applications to create a strong and stable connection between a fixture and a concrete base. When installed, the wedge anchor expands as it is tightened, which allows it to grip the concrete securely. This expansion creates a mechanical hold that provides excellent resistance to pull-out forces and shear loads, making it ideal for fastening applications that require durability and strength, such as mounting equipment, securing railings, or anchoring heavy machinery.

Other options do not accurately represent the main use of wedge anchors. For instance, using wedge anchors to secure electrical components is less common, as they are not specifically designed for that purpose. Similarly, expansion in drywall or for attaching lightweight fixtures does not apply, as wedge anchors are specifically engineered for solid concrete rather than softer materials like drywall.
