Insert wedge anchor, clipped end first, into the predrilled hole in the concrete. Wedge anchors can be installed deeper in the concrete than the minimum embedment depth and will provide better holding values as long as the depth of embedment is not taken to extremes. Categories. Wedge anchors are very effective when the concrete is in good condition and minimum edge distances and spacing are maintained.Hole size is critical to the holding values of the wedge anchor. As the wedge anchor is pounded in, it may stop at some point. Begin by drilling holes in the concrete with a hammer drill. so if your installing a 3/4" anchor you need to use a 7/8" drill bit.
