Oddball Metric Threads

Oddball Metric Threads

Oddball Metric Threads

(OP)
  I'm a QC Tech for a Communications Assembly Facility here in Connecticut.  
  Today I had a visit from a Toolmaker, asking me for the tolerances on an M29 x 1.5 thread.
  Wouldn't ya know the Machinists Handbook skips right over the M29's!!
  I realize that M29 is the definer of the Nominal (29mm) and the 1.5 represents the threads per revolution, but what are the tolerance ranges for the Major and Minor threads I haven't a clue.......
   Someone got an answer?

RE: Oddball Metric Threads

btw, major is considered the max. diameter.
eg. for a bolt of M6X1, the major is 6mm, so M29X1.5, the major is 29. Minor you can calculate. The angle is 60°

Good luck
