Where can I find metric socket wrench clearances ? I looked in the machinery handbook, but in vain.

Why not just measure one?

Depends on the wrench.  I have some Craftsman sockets that have almost double the wall thickness of the same size Snap-On socket.

Socket diameters can vary, by quite a lot, for both metric and imperial tools.  Depends on the manufacturer, type of steel and expected use of the socket.  Oh, and cost.

I remember seeing the dimensions in tool catalogs for tool product names like Proto that you can get from auto and truck parts houses.

Try this for a start;

There is a MS standard, I can't find it right now.

vscid - Tolerances for metric wrenches are listed under DIN 475-2 or ISO 691.
If you need just a few - post what size and I will get it for you. If you need many sizes - google and you may have to buy a book. Best source - "Beuth" ask for their English version of DIN 475-2 or ISO 691.

Just going to throw this out there, but any chance you would be able to let me know what the tolerance is for a 7mm wrench?  

It would be greatly appreciated.

Tolerances for a socket wrench?

Realistically, can you really expect your "average" mechanic or millwright to have a socket in his toolbag that is so close to "not fitting" - given the above where socket walls between manufactorers and suppliers so differs greatly! - that you (as an original designer) needs to consider fabrication tolerances in order that HIS socket will fit between YOUR nuts?   

I think you need more space.  Or a specific, designated socket wrench YOU will supply WITH the machined flange YOU are selling that will permanently stay with that flange for as long as the flange will need maintenance...

I found my answer in another thread.  Thanks.

Looking back I guess my question was not clear.  I was looking for the standard clearance range between the flats of a open faced wrench and a nut/bolt head (DIN 475-2).  I would like to use a hex head bolt in a non traditional way and want to insure that there is never an interference, so I figure the easiest thing to do is mimic the clearances on a wrench since there is never an instance were a wrench does not fit a nut/bolt.

So again sorry for not being more clear, and making you waste your time with an answer that is not applicable.  Good day

As a quick check on project I have just used a standerd flat washer.  If a standerd flat wash will fit then there should be room for the socket wrench.

You might want to check our Maryland Metric.
They have a lot of tech info on their site.
