Typical industry values; there is no single dimensional standard. Grip range must match your sheet thickness. Moulding inserts are made to the mould drawing.
Parts are checked at each stage with vernier calipers, micrometers and visual inspection. Material and test reports can be arranged on request.

Questions
Rivet nut or press-in insert?
A rivet nut is set blind from one side, which suits tube and closed sections. A knurled insert is pressed, heat-staked or moulded into plastic or wood.
Why does grip range matter?
Too thin and the rivet nut spins in the hole; too thick and it can't collapse fully. Give us your sheet thickness.
Can you make inserts for injection moulding?
Yes. Knurled brass and steel moulding inserts are turned to the mould drawing.
