Drive sizes?

Here in America, our standard drive sizes for sockets are 1/4, 3/8, 1/2, 3/4 and 1". I was just curious what sizes are used when the metric system is the primary measurement in any given country.

well, the sizes are universal. if you look in some of the German tool catalogues (ie Hazet, which is well worth a look) they list the sizes as 6.5mm, 10mm, 12.5mm, 20mm and 25mm. of course, these are just the metric equivalent for the imperial sizes.

If you were going to ask someone to hand you a certain socket, How would you say it?
"Hand me (whatever size) in a six point five drive"???
or "in a six five drive"
or "in a sixty five"
???????

I am going to ask someone for a socket tomarrow in a "twelve AND A HALF" silly-meter drive. :lol:

:p

to be honest, i don't know because here in the UK we use the imperial sizes. i believe that most of the other countries that work in metric also refer to drive sizes in imperial, but it's just the tool manufacturers that list tools by metric drive sizes.

i've seen german eBay sellers refer to tools using imperial for the drive sizes, but other than that i'm not really sure.

There is another drive size you never heard of and Snap On made them, 1 1/2 drive.I do not know if they make them.I do have an Uncle that is British,My Uncle Steve.He told me that the British call a wrench, a spanner.I hate the metric system for fasteners,5 differant thread pitches of metric bolts.

yes, we refer to "wrenches" as spanners. 1-1/2" isn't something created by Snap-on, it's just a larger drive size reserved for industrial applications. Ingersoll-Rand make 1-1/2" impact guns and sockets. there are drive sizes above 2". they're just mainly for industrial applications.

Don't forget about "Spline drive" its about 1"....

yeah, #5 Spline is pretty much level with 1". althought i've only even seen #5 Spline to 1" adapaters and no direct #5 drive sockets. maybe i'm looking in the wrong place.

There is another bigger drive size, 2 1/2.I just found this in a 1975 Snap On catalog with a price guide,new products guide that I bought on Ebay.It did have 1 1/2 drive in the catalog too

3.5" square drive sockets! I wonder how many ft. lbs. those can take.

I have heard of the biggest sized sockets used,13 5/8".This one is used in power plants and I heard this from an industrial Snap On dealer about 10 years ago.

Buy me the set and an impact for them too......they can't be THAT much. :lol:
....Wonder what Snappy would want for them...:lol:
they hide the prices on the 2 1/2" sockets...

I'd guess $4,000 for the impact, and $500 per socket.
Our Matco guy comes on Fridays, I'll ask him what they cost from him. Anytime anyone asks our snappy dealer for a price on something, he orders it and expects you to buy it.... and he wonders why people avoid him :shakehead . A guy I work with bought a tube of air ratchet grease... snappy comes in the next week with a tube of grease... and an air ratchet!

, and $500 per socket.
More than that I'm positive. We were going over a Snap-on price book and there were sockets in there for 2,000 and even one for 5,000. I'm not sure what size they were I want to say one was a 5 5/8" socket, but its been over 2 years ago. I know the spline drive stuff was more than the regular sockets.
Our tool guys always complain when one guy there (he is annoying though) prices a bunch of stuff and then doesn't buy anything. It funny because he wont buy any new tools at all, cheap or name brand.
There are times when a guy will ask about an item and our Snap-on dealer will order it in just so he can look at it. I guess he just ships the stuff back if the guy don't want it, he never complained about ordering it.

sockets in there for 2,000 and even one for 5,000.
