What size expansion anchor do I need?
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”.
