Here's a question for you. Is it possible to buy metric spanners with close tolerances? I've recently removed some brass components from my car but couldn't find suitable spanners. I have now measured these components with a micrometer and found that I was actually using the correct size spanners even though they were a little bit loose. Of course, using a loose-fitting chrome vanadium spanner on brass causes damage to the brass. One of the components measured as 11.00mm and the other as 19.00mm (cold), so they are precision made components. My 19mm spanner is about 19.3mm, measured with vernier calipers. I have a similar problem with sockets.
