    Guide for thread data parameters in toolbox?

    Kevin Shields

      Hi All,


      I would like to add a tapped hole specification to the solidworks toolbox, but I'm not sure what the various parameters mean (minor diameter inside, advance, etc.). Is there a guide that indicates what these parameters mean? Or could someone help translate these for my part?



      Here are the specifications I have:


      External Thread, 1.035"-40.0, UNS-2AInternal Thread, 1.035"-40.0, UNS-2B
      Max Major Diameter1.0339"Min Major Diameter1.0350"
      Min Major Diameter1.0288"Min Pitch Diameter1.0188"
      Max Pitch Diameter1.0177"Max Pitch Diameter1.0234"
      Min Pitch Diameter1.0142"Min Minor Diameter (and 83.3% of thread)1.008"
      Max Minor Diameter1.0068"Max Minor Diameter (and 64.9% of thread)1.014"

          I only do this a couple times a year so I cannot give you specific instructions.  However, I will share my process.  What I do is look up a known thread size (already in the table) then compare it to thread specs I find in either the Machinery's Handbook or online.  Once I understand which parameter is which, I then enter my new thread size.  Hope this helps you.
