For items having a thickness (or height) exceeding two times the outside diameter, use post, electrical-mechanical equipment. See also nut (1), plain, knurled. (when height or thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance.)
