    Secure heavy machinery with constant motion, such as vibrating feeders and conveyors, in concrete floors. The wedges on the base of these anchors have ridges that lock them in place, so they won’t shake loose. Since the grip is focused at the base, these anchors are best suited for concrete, which can handle the gripping pressure better than softer block and brick. However, they require holes that match the anchors' diameter exactly to achieve their pull-out strength, making them more difficult to install than sleeve anchors.

    To install, drive the anchor through your machinery into a drilled hole until the washer meets the surface. Use the notches along each side of the anchor to locate the wedges, directing the gripping forces away from seams and corners to prevent cracking the concrete. Then, tighten the nut to expand the base wedges. Remove your machinery by unfastening the nut, but the anchor itself cannot be removed.

    Zinc-Plated SteelThe most common choice for areas with occasional exposure to moisture.
