IMPORTANT:
If the determined drill bit diameter is not observed:
- the knurling on the straight shank rivet nut is rendered useless
- the component will be damaged when the straight shank rivet nut is inserted
Determining suitable drill bit:

Depending on the rivet nut shank diameter, the next drill bit diameter higher (5/10 step) can be used.

E.g. with a shank diameter of 10.1 mm, the 10.5 mm drill bit can be used. The 11.0 mm drill bit must not be used.
Drill bore with determined drill bit and deburr, pilot-drill with a smaller drill bit if necessary
