Well the forces which actualy lead to tensile forces on the screws are mostly not the biggest challenge.
In your case the walls arround the screws are thin an if you simulate lateral forces, there wi ... |

Normally i draw the model centerline, for example Ø10 +/- 0.05,
except from special tolerances as h7/H7 like Glen said before.
Depending on which cad you use, there are several options.
I ALWAYS ... |

Well it is indeed really important to set tolerances, if they are important for the function.
I alway send a .step or .dxf dataset with the parts.
And of course your drawing shuold be, as clear as p ... |

I have been working for years with different tooling machines, ... |
