Metric or SAE?

LD1 · Apr 13, 2012

If you are going to do any of your own wrenching these days on about anything...metric is a must have. Used more than standard on about everything I own.

And after awhile, you will get good at knowing what wrenches you can interchange. Like 8mm-5/16, 11mm-7/16, 14mm-9/16, 16mm-5/8, 18mm-3/4, and so on. And there are others that are close so if you round off a rusted bolt, you can go a hair smaller and be able to pound it on with a hammer:thumbsup:

USA, Liberia & Burma are the only countries left not on the metric system.

So, unless it is built by one of these three countries for domestic use, it will be metric.

This is your excuse to buy more tools.

I just found need for a 1-3/16 on my Mahindra hydraulics. Not 30mm ... close but too small. I think India mixes english-metric.

Takes a very large 18 to fit 3/4. 19mm = 0.748"

Typo. I meant 19. Good catch

It is pretty easy to remember The ones that interchange....11,14,16,19....because I am used to wrenching on cars alot, and THOSE are the ones they NEVER seem to use:confused2:

Its always 10, 12, 15, and 17

For sockets, Iv always thot a metric set covering every mm with a 3/8 and 1/2 added will cover everything. For open end wrenches you gotta be closer tho. Im about to buy a 1-3/16 for just that reason ... unless I decide to grind a 1-1/8 up a size.
