SCREW THREAD GAGING SYSTEMS FOR DIMENSIONAL ACCEPTABILITY; ERRATA - FEBRUARY 1980
|Publication Date:||15 October 1979|
This standard presents screw thread gaging systems suitable for determining the acceptability of UN, UNR, and UNJ screw threads on externally and internally threaded products. It establishes the criteria for screw thread acceptance when a gaging system is used.
A screw thread gaging system comprises a list of screw thread characteristics that must be inspected to establish the dimensional acceptability of the screw threads on a threaded product and the gage (s) which shall be used when inspecting those characteristics.
