Length of a Wedge Anchor

Determining wedge anchor length is crucial prior installing. Wedge anchors come in various diameters and various respective lengths to the diameters. Wedge anchor of a certain diameter must be embedded into the base at a minimum depth.

The below table maps the diameter of a wedge anchor to minimum embedment depth required.

Diameter of Wedge Anchor Minimum Embedment Depth
1/4” 1-1/8”
5/16” 1-1/4”
3/8” 1-1/2”
1/2” 2-1/4
5/8” 2-3/4”
3/4” 3-1/4”
7/8” 3-7/8”
1” 4-1/2”
1-1/4” 5-1/2”

 

Installing wedge anchors deeper than the minimum depth embedment can provide better fixation.  Make sure depth of embedment is not taken to extremes.
