Prowler V6

[dzorde at erggroup.com]

Yeah, there are the Asian metric sizes (like 12mm, 15mm, 18mm hex heads) and
European metric sizes (like 13mm, 17mm, 19mm hex heads).  And lately I have
started finding 3/8" nuts and bolts with 15mm hex heads (I was quite surprised
to find that neither a 9/16" or a 5/8" ring spanner would fit, but a 15mm did)

A lot of newer american cars are now using a mix of metric and standard in
their cars. Oddly though these sizes seem different than what standards are in
the rest of the world. For instance most european hex head fasteners have head
sizes 10,13,17,19,22,24,27mm not sizes like 15 mm and 18 mm
Anybody know why? are these maybe JIS (Japanese) as opposed to DIN (German)
standards?
Or did the american auto manufacturers buy stock in the tool companies?
