Unified 'MOD' screw thread?
Unified 'MOD' screw thread?
(OP)
Hello all,
I have a drawing that refers to a UN-2A MOD thread.
Can anyone explain to me the implications of the MOD suffix?
The drawing details the limits of the major, pitch and minor diameters etc.
Regards,
Lee

RE: Unified 'MOD' screw thread?
Essentially as I understand it the same pitch diameter as the standard thread but with modified major diameter (screw) or modified minor diamter (nut).
However, unless a UNS with modified crests I'm not sure why the pitch diameter is given.
KENAT,
