http://www.garagejournal.com/forum/showthread.php?t=202187It seems like everything is metric these days how much sae stuff do mechanics keep in their box other then working on classics do they ever get used
I’m curious about the general membership on this subject.
I’ve seen several posts saying basically “SAE tools are a waste don’t by them”
While most of my vehicles are mostly metric, I still use SAE at least as much as I do metric, but my use is not restricted to just cars or just a work environment.
So how about it people? What is your approximate use ratio
I wondered if I could find out some info. on which applications use SAE fasteners and which use metric. What I found so far:
1) foreign vehicles use metric, incl. those assembled in the U.S.
2) U.S. vehicles currently use metric, used SAE in the past.
3) Some things around the home still use SAE. For example the casters on my office chair were getting loose, and a SAE combo wrench was ideal for tightening the hex nut between the caster and chair leg.
4) Not sure about home appliances (dishwasher, clothes washer and dryer, etc.)
It's all I use at work.
Yep, as much as metric. Couldn't get by without them. This has been discussed a million times........almost as much as the downfall of Sears and Craftsman.

Just out of curiosity, what is the rational for the aircraft industry sticking with SAE?
Is SAE used on Airbus products? How about Rolls Royce engines?
Still lots of old cars running around in case. I still use mine. Maybe not daily,weekly for sure.

World standard.
Nonsense. SAE is due to specialized hardware set up by the first country to produce aircraft in volume. The good ole USA.World standard.
IMO adjustable wrenches and Visegrips are rarely the right tool.
