* These figures give the outside diameter for screws with threads cut theoretically sharp. As it is not practical to make these threads sharp, the outside diameter will measure less than the figures given, the pitch diameter remaining the same.
AMERICAN STANDARD ACME SCREW THREAD DIMENSIONS p Fc 29º h' h = Basic depth of thread Fc = Width of flat at crest of thread Kr = Minor diameter of screw
h' = Depth of thread with clearance Fr = Width of flat at bottom of space D = Major diameter of screw K = Tap drill
n = Number of threads per inch Basic minor diameter of nut p = Pitch of thread T = Major diameter of tap
