Hi all, need your help.
can any body explain to me what is the meaning of "6H" in picture attached. and how to remove it from hole call out description?
The "6" refers to the class of the thread.
The "H" or "G" means a lower deviation for internal threads.
An "h" or "g" means an upper deviation for external threads.
This is per the machinerys handbook under Metric threads.
These designations are much like the "2A" or "2B" for english threads.
6H refers to the fit of the thread. When say 5H is used it will be a looser fitting thread. 6H is just a common size.
Go to your solidworks directory folder on your system to manually change the calloutformat.txt - Solidworks\lang\english\calloutformat.txt
Make sure you choose the right heading for what kind of hole your dimensioning i.e. Ansi Metric - Tapped Holes - With cosmetic Thread
Thanks for the explaination......and i have already edit calloutformat.txt..and it works!!
When creating the tapped hole, deselect the Thread Class option at the bottom of the Hole Specification panel.

No problem. If you can get a machinery's handbook it is filled with info like this.
