ASME B18.2.2 Hex Coupling Nuts
(1) Nuts shall be furnished without a hole, unless specially ordered by the purchaser. In some
applications it may be desirable to assure that the threaded parts joined by a coupling nut are
each engaged to approximately one-half nut thickness. As a visual inspection aid, a hole drilled
through one side of the nut is recommended. The hole should be located at mid-nut thickness,
and have a diameter of 0.2 to 0.4 times nominal nut size for sizes 21⁄2 in. and smaller, and 1 in.
for sizes 23⁄4 in. and larger.
