It's not a $$ thing, just a toolbox room issue. I'd prefer to fill my box with tools I use.
There isn't an SAE I'm confusing with metric...hehe. Of course if it was a size that both fit it really wouldn't justify buying SAE anyway, right?
GM doesn't mix and match SAE and Metric like that. Certainly not on anything since 2000. Only SAE item on the car is a 5/8" spark plug...which of course you wouldn't use a combo wrench on.
That's got to be tough to do in WhitworthAnd I can't help but buy quality made in the USA hardware, so it's seeming to add up to mucho dineros.

I thought this was it? Or did you want somewhere that helps you <i>not</i> buy more tools???This whole tool buying mania is becoming a bit of an expensive addiction. Is there a tool buyers anomymous self help network or something?

GM absolutely does mix and match like that and did at least through 2002 on my car, I know that for a fact. What I don't know for a fact is how long they continued after 2002. The two closest sizes don't both really fit unless you are happy with sloppy fits. If you are happy with sloppy fits then just use metric on SAE fasteners. Suit yourself. Many do it, I just won't.
It all seems rather foolish to be worried about saving the space of a set of SAE wrenches in a tool box when so many things - even if you have a german car - are SAE.

Oh? See my earlier post regarding my 2002 Chev Astro.
I'm curious, now, if this is true in countries that have adopted the metric system overall. Are, say, Spanish tractors all in SAE? Are Hungarian diswashers SAE?Seems like SAE is still quite common outside the auto industry.

Are all AN fasteners SAE (inches)? If the racing industry still uses these "super" bolts, screws, and nuts, then are SAE wrenches then still much in use in racing? I note the racing parts store Pegasus sells these high-strength, fine-tolerance fasteners only in SAE.
I actually wish everyone agreed to use one standard from Day 1

Most AMERICAN autos before 1984?
For example, the latest LS engines (LS3 and LS7) still have a few S.A.E. bolts.
You found 4 bolts. I'm referring more to the suggestion by mrmark that you have to check every bolt b/c you don't know what to expect. I'm not refuting that you may find an odd SAE bolt (though I've never once ran into one on a newer us car).
******* matches aside, this thread has been good to understand where an SAE set is useful. I'll admit I'm still not convinced an SAE wrench set is important for modern auto work based upon a rare SAE fastener finding. (assuming you have a small SAE socket assortment)
Name one in an LS engine. Heck, name one OEM bolt in a C6 that is SAE. Back up those claims since there are supposedly a few...
Id be happy to eat my words, but I sure cant think of one. Rod Bolts are M9.


Never worked on an aircraft that used metric fasteners
Sometimes I use SAE when working on metric stuff if I need a wrench slightly looser or tighter than the metric size. For example, if I'm working on a rusty 16mm bolt I'll use a 5/8" (.005" smaller) for tighter fit. Not every time, but sometimes you need to find the best fit.
Do the aircrafts from Europe, Canada, and Brazil use metric or SAE? Just curious.
