Drilled out how much?

Revise the above studs are 3/16” too long.
I could easily solve the problem with a spot face tool in my drill press.
Also:
The holes in the plastic parts need to be drilled larger. Way too much interference fit with the self tapping screws.
Snapped the head off one and had to drill it out.
