Hi
Yes, the seatbelt bots are 7/16ths UNF/NF If you are creating a new thead for those the tapping drill size is 9.9mm. The exact reason I keep all of my imperial stuff here, tis surprising how often I have a use for one of em

Some of the imperial thread sizes/pitches are a little confusing.
NC & UNC are both the same NF & UNF are the same The threads of the seatbelt fixings are most commonly called 7/16 UNF & has 20 threads per inch ( Also known as 7/16 NF20  )Hope that helps
