Anybody know where I can get a copy of wrench sizes both american and metric all in one list/chart. Sure would make it easier when going to the tool box and grabbing wrenches/sockets if U had this list to refer to.

Hmmmm.... it took out all the white space..... oh well

I think you can probably figure out what it used to be

By law, 1 inch = 2.54cm. Do the math.

In my experience, 1/2" is close to 13mm (mm slightly larger), 9/16" is close to 14mm (inch slightly larger), 3/4" is close to 19mm.

It is a little frustrating to have both on the car. 15mm nuts and bolts are all over the engine compartment, most metric wrench sets don't include that size, and no SAE size is close. I've had sockets & combo wrenches for several years for that size. Another is the LCA bolts - 18mm - wrench sets don't include that size, no SAE size is close, so I went out and bought 3/8" and 1/2" drive 18mm sockets and 18mm combo wrench in the middle of changing out the diff.

guess i'm a little slow here but other than my first thought of "why" is wouldn't you want to use the correct tool or size for the job?

Amen.

I carry both SAE and metric "emergency" tools in the trunk of the Camaro.

10mm is a pain too. And alot of bolts on these cars are 10's.
Here's what I've learned from past experiences:
8mm=5/16"
13mm=1/2"
14mm=9/16"
15mm=5/8"
19mm=3/4"
21mm=13/16"
22mm=7/8"
*** note: these are the closeset sizes, there may be some slop, but will work in a pinch.
Just go buy a metric set, so you don't wind up rounding off bolts...

Yeah; I don't think I'd substitute, but if I'm stacnding there and I've got a metric bolt that's a little smaller than a 11/16" socket, it's nice to know which one to go for next. Or vice-versa. You can look down that list of decimal equivalents that the board turned my table into, and see how close some of the metric and SAE sizes are.

Thanks this is exactly what I wanted!!!

I have down loaded this printed it out, and put it in a plastic laminent and is now attached to the inside lid of my tool box!

I am sure others will appreciate it. I'm tired of guessing what size to grab and taking a hand full out to the car--now at least I can make an educated guess!

THANKS AGAIN!!!

fixed it for ya.
in the future, to keep spacing in tables, put it between the "code" brackets... aka the # button on this board

Too bad that looks so much like actually doing work!!!

But at least 10mm is common in wrench/socket sets.

Forgot about that one. Battery cables.

Not in my experience. Especially with 12-point.

@ RB. Just got my coffee too you bastard!!

Oops, it's been a while since I had to use that one, (crossmember?) I think it is actually 16mm that is correct, but it still has play.

somthing i learned a long long time ago.

its better to take 5mins out of your work to find the right tool, then it is to use the wrong one and spend hours fixing what you foorbared.
