Technical Specifications for Wedge Anchors

Technical Specifications for Wedge Anchors

Technical Specifications:
To ensure safe and proper wedge anchor installation, certain technical specifications must be considered. Wedge anchors come in a variety of diameters, lengths, and thread length and are available in three materials: zinc plated carbon steel, hot-dipped galvanized, and stainless steel. Wedge anchors should be used only in solid concrete.

Length:
To determine the length of wedge anchor required, add the thickness of the material to be fastened, plus minimum embedment, plus the thickness of the nut and washer. The sum of these three items equals the minimum wedge anchor length. The Wedge anchor requires no maximum hole depth. The depth of the hole in the base material should be at least the length of the anchor minus the thickness of the material being fastened. This will provide some extra depth to accommodate a minor amount of concrete cuttings which may not be able to be cleaned out of the hole.

Spacing:
The forces on a Wedge Anchor are transferred to the base material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor. As a rule of thumb, the expansion anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from any unsupported edge. When vibration or sudden impact are part of the load conditions, the spacing between anchors should be increased.
