That wrench is 12mm. And try not to use an open end but always - when possible - a close end and the best is 6 sides instead of 12 sides.
Make a picture so we know were you are working.

Herrie - the seat belt upper bolts are 17mm.

They are sometimes very difficult to remove and very laborious - on some they only just clear the body when on last threads prior to coming out....

Reason they have been in what seems a silly place is like a few other things on the m3w, the body is put on after the rolling chassis is completely built redcard
