Installing wedge anchors can be completed in five easy steps. Wedge anchors can be used in solid concrete applications, are best suited for light to heavy-duty fastening purposes, are available in diameters from 1/4" up to 1-1/4", and are available in standard zinc plated, hot dipped galvanized and stainless steel. To determine the minimum anchor length for your application, simply add the material thickness to the minimum embedment and add the thickness of the nut & washer.

Installation steps:

Hammer wedge anchor into hole deep enough so that threads are below surface of base material. Drill hole 1/2 ” deeper than wedge anchor embedment using a carbide tipped bit. (Hole size is wedge anchor size). Tighten nut turning approximately three or four full turns.
