Why are seatbelt fixings UNF?
As per title really, why are seat belt bolts and sleeves always UNF? Why can't you use metric bolts?

You can use metric - can't remember the recognised equivalent just now, but as long as it's the right size & grade then it's OK.

Its down to US Federal Law, the requirement is 7/16 UNF or 1/2 UNC.
I believe it has been amended to say or metric equivalent now, but guess manufacturers just stuck with existing tooling.
