Remove the bolt to adjust, move, or replace components. Manufactured in the U.S. with Grade 5 steel, these anchors have over twice the shear strength of our wedge anchors, making them strong enough to secure highway barriers and train tracks. When you tighten them, the tapered bolt expands the nut, spreading the gripping force along its entire length. This creates the higher strength than wedge anchors, where the grip is focused at the wedge. These anchors are more forgiving of variations in hole precision than wedge anchors and require more torque to install. The increased torque puts stress on your base material, so don't use them near edges, corners, or in cracked surfaces.

To install, thread the nut onto the tapered bolt. Drive the anchor through your component into a drilled hole. Then, turn the bolt to expand the nut for a tight hold. You can repeatedly use the bolt in the same hole. To use the bolt in a new hole, a replacement expander nut (sold separately) is required.
