Wedge Anchor Fasteners

What are Wedge Anchor Fasteners?

Wedge anchor fasteners are heavy-duty mechanical expansion anchors used to secure objects to solid concrete surfaces. They consist of a threaded stud, an expansion clip, and a nut and washer. Once inserted into a pre-drilled hole in concrete and tightened, the expansion clip wedges against the walls of the hole, providing strong, reliable holding power.
