all my SO tools are metric. for what i work on, i never need SAE sizes.
There's a current thread on Practical Machinist on this very topic. Might be interesting reading for some here.

Ha. I get the idea...but this "half-size" concept isn't valid or accurate. That measurement description is indeed just like it sounds..."1/1000" represents a piece of a size which one thousand pieces will make up one inch. There is no other way to look at it, but I can see how it might be confusing to others.so, is it really 1/1000 or 1/1024 ?
I mean, natural progression of dividing by two leads us to the number 1024. Just like the metric prefix 'Kilo' used in computer systems. When we say 'kilobytes', the metric system dictates it's supposed to be 1000 bytes, but in actuality it is 1024 bytes (since 2 to the power of 10 is 1024) But we say 'Kilo' anyways...
So, when we say 'one thousands of an inch' is it really an inch divided into 1000 pieces or is it 1024 pieces??

i like metric![]()


can we share tools?![]()
I would be happy if they went with one or the other and that's it. Dodge is bad about it, 1/2 metric and 1/2 SAE... and a few that are a WTF size since it's I guess in between or something!

Don't own any imports, work mostly on old stuff for fun.
At work i work ONLY on Nissan 350Z/370Z and the Infiniti G35/G37, and i still have more than just basic SAE sets. While the cars are 100% metric, the fittings on our twin turbo, and supercharger kits are all AN/JIC/NPT which are all SAE. Even the aftermarket turbos still have SAE threads. Then we can get to the machines (mill/lathe/sanders/grinders/etc) that are all at least 50% SAE.
If you ever visit germany.....maybe
I don´t know but i think metric is easier. 10 mm is 1 cm. 12mm is 1,2 cm but what is it in fractional ??? Or if you measure 1/2" which is 12,7mm but what is 12,8mm in fractional ??? Or if you have to make a thread for a 8mm thread you need a 6,8mm drill bit. But if you don`t have metric drill bits which is the fractional equivalent ? 17/64 is close (ca. 6,75mm) but how do you know that without calculating ?? a big mess....
Oh yeah I also own sets of SAE and metric but the question was "who still buys SAE?"

You know, it's a lot like learning a second language. I know a few words of Spanish, but when I hear or see words in Spanish, my brain must first convert them to English before I can understand the meaning. And if I want to say something in Spanish, I must think of it first in English, translate it in my head, and then say it...which is WAY slower than it would be if I could generate the original THOUGHT in Spanish in my head.
I grew up learning wrench sizes to hand to my dad, and before long it became second nature for me to understand the natural progression of the fractional sizes...even before I had them all memorized (IE: 5/8 is instantly obvious to be the same as "10/16", so the next size up is 11/16, when working in sizes found on American cars of the vintage I am familiar with.) Today when I see a nut or bolt, I THINK in fractional sizes like 7/16 or 7/8. Like every wrench-head my age, I can naturally hold two fingers apart to approximate sizes like that. But when one of my car buddies who works on current cars describes something to me in metric sizes, I must ask them to "translate" it into approximate SAE sizes, before their description of the item means anything to me.
I also understand that metrics are easier to calculate and work with, ONCE YOU KNOW THEM. Everyone gets it that 11 mm comes right after 10 mm, and that 20 mm is twice the size of 10 mm. But dinosaurs like me...I can spot a nut or bolt which requires a 9/16 wrench from 3 feet away (about 1 meter). But a centimeter and a millimeter means nothing until I get out something to measure it with. I can accurately estimate 1/2", 2.5", a foot, 8 feet, and 20 feet very quickly, due to a lifetime of practice. But when I read a thread here where someone is talking about how to deal with something like a "20mm" bolt...my mind is blank. I don't know whether it is about a half inch in diameter, or an inch...or 3 inches.
Like I say, today's young Americans are all being taught metrics, and MOST cars are now MOSTLY metric. So I am a dinosaur, and America will continue to become a metric nation...without me.![]()
OK, back to the OP question. In the last year I bought SAE and Metric 1/2" deep impacts, SAE and Metric Flare wrenches, a combination SAE and Metric Socket set and 3/8" and 1/2" drills. Where are the metric drills anyway?![]()
I have ten fingers, don't know about the rest of Ya'll. Apparently the King of England was blessed with 12 hence we have that asinine system.
Luckily, it does seem that more and more american products are starting to use metric fasteners.
Metric is for girly men.
what kind of stuff you work on? if you make a living wrenching, would you tell your customers to get the hell out because their cars have metric fasteners?![]()
for me, I have both, my own cars are all metric from factory, but the the add-on aftermarket stuff are mostly standard. my lawn mower is metric.
the cars I work on at school are mix bag of metric and standard, often times on the same car.
I buy standard stuff for things around home because normally they are cheaper than metric.
metric, never touch the stuff, I'm an AMERICAN, DAMN IT!
+1. Most medium & heavy duty's still have a little SAE hardware (Freightliner chassis' are nearly all SAE). Nearly all aftermarket bodies & equipment are still SAE.......PTO's and clutch pumps, beds and accessories, hydraulic fittings and hoses, although I am starting to see hydraulic fittings that are metric but with standard ol' SAE threads.
A lot of the PTO's I hang have metric/SAE studs. The end that screws into the trans case is metric, and the end that holds the PTO on is SAE.The same goes for clutch pumps...they can be a mix too.
Lolol, your so called American system came from England, theres nothing to be patriotic about here, they are just different systems.
I am all about a switch to the Metric system. The Imperial system is so unorganized. 12 inches in a foot. 3 feet in a yard. 5,280 feet in a mile.
For example, which is easier for you to calculate? How many feet are in 4 miles or how many meters are in 4 kilometers?
