Like most on here I've got lots of spanners.
Sticking with metric sizes, I've noticed that the majority of my spanner
work is with 10mm and 13mm sizes which corresponds to M6/M8.


So what are the other ones for in spanner sets, ie., 9mm, 11mm, 12mm,
14mm
and so on. Are they just there to make the numbers up or make it
harder to
find the one you want?

Certainly 100mm, 13mm, and 17mm are the most common, but other sizes
crop up. One VW I've had needed 15mm on part of the front brakes, and
they're relatively hard to come by, and not in most sets.
****. *10mm*. 100mm would be interesting.

I used to have one that I think was 75mm, to remove the inspection plugs
in the ends of the air receivers for my compressors. It needed two hands
to lift it.

Contraplan, office furniture manufacturers of Rugby (Now defunct) used to supply tables with bolt in legs. The nuts were Whitworth. They had to be done up as tightly as possible to keep the table stable and only about 1/4 turn of swing was available. Real ******* and it had to be the right size spanner or the nuts quickly rounded.
