Re: Door hinge bolts
You'd have to Drill First - and ( If I was going to do something like this )
I'd use a - Forming Tap - which can be done in - Two Stages . .

Is Class 2A - and Class 1B Being Sloppy Crap from China .. Type workmanship ..
If You really want Great Class threads then Get Forming Taps made to do " J " Threads
