I put this question at the bottom of an overly long reply on the "Best
Tools" thread, so It probably didn't get read by too many folks, so I'll
ask it again he

*******************************************
Is the "international standard" for socket wrench square drive sizes
still only the english 1/4", 3/8", 1/2", 3/4" etc., or have they started
manufacturing metric sockets with metric sized drives and (G-d forbid)
maybe even inch size sockets with metric sized drives?

Just wondering...

Well you left out the 5/16" and 5/8" drives from the past. :-)

Greetings:

Every socket drive that I have seen sold in Europe is based on inch system.
This includes major tool dealers such as Hahn & Kolb, etc.

What about tire sizes?
Even imported cars use 14" 15" tires etc.
Don't they? ? Enquiring minds...
And gas pipe threads are based on English pipe thread sizes.
1/4-18, 1/8-27, etc. Even in the Metric countries.

Any other examples?

(My point is, some things seem to stay english, even in the
metric world. )

Yeah, they've got metric: 6.35 mm, 9.52 mm, 12.70 mm and 19.05 mm are
the usual square drive sizes in Europe and Asia.

If you do your math...
6.35 = 1/4"
9.52 = 3/8"
12.7 = 1/2"
19.05 = 3/4"
Dead on...

Gee, you noticed that too! Coincidence? Nahhhh.... ;-)

You remember right Jim, and some of them also disassembled for cleaning!

Here's one like that I picked up at an antique shop in Minnesota a few
years ago. A copper gasket seals the porcelain to the body.

Dual ground electrodes too!

Before someone jumps on me, the copper gasket seals to the metal band
fused to the porcelain, OK?

Jeff

What is something like that worth? I think I have one in a box out in
the shop. I didn't realize it came apart.

I bought two from a roadside antique/junque shop. IIRC I think I paid
about $12 for the pair. They were pretty well rusted and the hexes
somwhat rounded off. I kept one and gave the other to an rcm poster
there in Minnesota.

I'm sure a virgin one in its original box would have a higher value to a
collector, and as I've discovered since the advent of the internet and
eBay, there are collectors of EVERYTHING. You could always list it on
eBay with a high enough reserve to make you happy if it sold.
