The document prints no HC-to-NAS table: HC3242 is read from its codes (324 oversize diameter, head 2 100° flush, aluminum sleeve, alloy steel spindle), so this needs engineering approval. Both number the diameter in 1/32 in. and the max grip in 1/16 in. (examples HC3242-5-04, NAS 9301 B H -4 -05).Dash numbers carried over: the cited document prints both part numbers with the same dash structure.
