Good info! I usually just grab around for a socket that looks the same ... but this would definitely make it quicker.
I just wish there was some rhyme or reason to when they used metric and when they used standard bolts/nuts on Corvettes. I swear sometimes the same piece has both types on it.

Here is what important for mechanics throwing wrenches around like me:
sockets, wrenches.
They are not equal but close enough.
7mm=9/32"
8mm= 5/16
10mm=13/32 (rare socket size)
11mm=7/16
14mm=9/16
16mm=5/8
19mm=3/4
Memorize it or... keep your wrenches in order!
