I always have problems understanding metrics.
I know that a 1/4 x 20 bolt means 1/4 inch diameter, 20 threads per
inch. That's so easy.
Then they shove metrics into our lives and all hell breaks loose...
I'm going to take a guess,
The "M" means METRIC
The "5" means 5 milimeter (mm)
The ".8" I dont understand at all. It's surely not .8 threads per inch,
or that would mean less than one thread per inch.
I'm sure the "thd" means THREAD
I googled this and 5mm is 0.197 inch, which needs a 4.20mm drill size.
(NOT what I was looking for)!
Damn, I hate metrics . . . . . . . .

How the heck old are you, anyway?? I'm almost 58, have lived in the U.S. my entire life, and
I was taught the metric system in grade school. You must be quite a bit older, *and* have
never had any education whatever in the sciences. *Everything* is metric in a laboratory.
Get a newer truck. I've owned three vehicles which were mixed, all of them from the mid-
1980s. My 1996 Buick was all metric. So is my wife's 1998 Mustang.
No, not really, it only seems that way to people who don't understand the metric system.
Without looking it up:
- how many yards in a mile?
- how many teaspoons in a cup?
- how many gallons in a bushel?
- how many gallons in a cubit foot?
Apparently it has not occurred to you to keep your metric wrenches in a different toolbox...
The you have to carry 2 tool boxes for many jobs. I remember working on
a car years ago and part of it was SAE and part Metric.
Not sure of the size of the spark plugs, but I bought a Datsun and the
first time I went to change the plugs I thought I would need a metric
plug socket. Asked the man at the Autozone parts counter and he did not
know. We took out a plug and started checking wrenches,. Found one that
was a loose fit. Then on a whim I checked a SAE plug socket and it fit
just fine. Did not need one as I had some at home.

That works if all your tools are the same brand - not all companies
make the differentiation in the same way - if at all.
Another solution is red or blue or black chrome for one or the other -
again only if allyour metric or SAE tools are the same.
Russia uses the imperial measurement system???
Russian measuring system of length is metric (centimeters, meters and
kilometers), so they do not use inches or feet in Russia. They use
grams and kilograms as the measuring system of weight, and Russians
are not familiar with ounces or pounds. Liquids are measured in
liters, rather than gallons, though strangely enough alcoholic drinks
are measured in grams. Do not forget about this when you buy gasoline
in Russia, as it is also measured in liters (there are about 4 liters
in a gallon).
Unlike in Fahrenheit-oriented countries, temperature in Russia is
measured in Celsius, or Centigrade (which is a former name for
Celsius). Or order to convert Fahrenheit into Celcius, use the
following formula: Celsius Temperature = (5:9) x (Fahrenheit
So, I'd have to say your "daffynition" is "daffy"

Only three countries have ever soft-landed on the moon, the United
States, the U.S.S.R. and now China.
Of those 3, only the USA has landed a live human on the moon.
So it depends on your definition of "been to the moon"
Uncle Monster posted for all of us...
was a most interesting project. The engine block was part of the frame. The diameter of the threaded part of the spark plugs was the largest I've ever seen. I could remove a spark plug and stick my finger through the hole in the cylinder head. The block had sleeves that we replaced and the darn pistons had 4 rings. I've never seen something like that then or since then. It was a fun job to remove the engine from the tractor, rebuild and reinstall it.
I just remembered, we took the generator off and installed a Chrysler alternator thus converting the tractor to 12 volts. ^_^
gray tractor and would do just about anything you asked the old critter to
do. The utter(pun intended) simplicity of the tractor made it easy to main
tain. It had an updraft carburetor and would run on anything that was as vo
latile as gasoline. I think the moonshiner down the valley had one that he
ran on his homemade fuel. We rebuilt the old tractor's engine back in 1970

FWIW, 4.2mm is a lot easier to find in a metric drill index than having to hunt thru fractional drills, number drills and letter drills.
I think the real problem is that US manufacturing doesn't know whether to shit or get off the toilet.
I had to get used to metric about 25 years ago when I changed jobs.
IMO, it is easier to use once you use it. The rest of world is trading
amongst itself and the US is sometimes left out because we are different.
