Wedge Anchor Fasteners
What is 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.
These anchors are ideal for structural and load-bearing applications in construction, industrial installations, and heavy machinery mounting due to their exceptional shear and tensile strength.

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