Wheel bolt dimension
Hi,
just a little help. Have to replace the 20pcs bolt that keep wheels (2011 V6 3.7). Are they metric or inch size?
From thread-counter, the thread seems to be ISO M12 x1.25, with 21mm Exagon, but online I've read they could be 1/2".
I've already purchased the M12x1.25, but before tring to tigh, want to be sure that i'm not going to destroy the thread.

I'm pretty sure it is a US thread -- 1/2" diameter, but I don't recall the thread pitch right now . . . do not force those metric nuts, yes they will likely damage the threads; they should thread on easily by hand
the nuts should fit a 21 mm or 13/16" wrench

What Bert said. 
They are 1/2" x 20 thread pitch. They are 13/16" or 21mm hex socket compatible.Here's an example of a set you'd need:
