Seat belt torx screw thread size to body

Hello, does anybody know the thread size of the lower Torx screw to the body underneath the front seat ?

I assumed it might be inch thread, but looks more as to be metric M12....my bolt thread is in poor condition. Anywhere to source? Rockauto doesn´t offer them, anywhere else?

I probably have a few. Are you referring to the one at the door, or between the seats? How long is it?
