What are Wedge Anchors and How do They Work?

Wedge anchors, also known as concrete anchors, are fasteners used to secure objects to concrete or masonry surfaces. They are commonly used in construction projects, such as hanging shelves, mounting machinery, and installing fixtures. Wedge anchors consist of a threaded rod and a expandable sleeve that is anchored into the concrete by tightening a nut on the end of the rod.

When the nut is tightened, the sleeve expands, creating friction and grip between the anchor and the concrete, which helps to securely hold the object in place. Wedge anchors come in a variety of materials, including stainless steel and zinc-plated steel, making them suitable for use in a variety of environments and conditions.
