The simple formula used to determine the length of the male fastener is done by adding the thickness of the material being fastened plus the minimum depth of embedment for the diameter of the anchor bolt, plus the thickness fo the washer and nut.
How long should my anchor bolt be?
As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used. For example, if a 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.
