10-32UNF is fine on 3/16" dia. rod.

The theoretical O.D. is .190". Actual male thread O.D. is always a few thou smaller than the nominal diameter.

10-24 might work better in aluminum. Use cutting fluid -- kerosine or WD-40 works.

That looks very close, but slightly too small.

3/16" is 0.1875

and asking for dimensions for a 10-32 screw I get:
