Hey Eddie

You don't need a thread guage.

If its stamped 180 that means its a 1.80mm jet which also means its metric.

If its metric fine or coarse you can tell what the pitch is by using another screw as a guage.

Use this as a reference

Once you have a pitch measure the diameter and you've got the thread, pitch and diameter.
