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.

Do you have questions?
They are used for securely anchoring items into solid concrete surfaces such as structural beams, machinery bases, and heavy equipment.
No, wedge anchors are specifically designed for solid concrete and are not recommended for brick or hollow materials.
While the nut and washer can be removed, the anchor itself is permanent once set. Removing the body usually damages the concrete.
Yes, we offer wedge anchors in stainless steel 304 and 316 for superior corrosion resistance, ideal for outdoor and marine use.
