The other reason is that if you need one size of such a tool, you'll use 
it to get the cover off and then find some other size of the same type of 
tool is needed to go further. Been there, done that :-)

Odd... I find the reverse. Plenty of places will sell me a set of 
spanners, finding a shop that will sell an idividual spanner is a lot harder.

The problem with ets is that they don't always include every size. Most 
UK-sets of inch-size Allen keys do not include 9/64", which is a stnadard 
size for a small UNX bold. You'll have 'fun' dismantling an ASR33 or 
getting the backplane out of a PDP11/45 without one.

And how many UK spanner sets include 11/32 A/F? An open-ended spanner of 
that size is esential for getting the PSU panel out of an HP9810 or 9820. 
I did manage to get one from a good local tool shop, it was _very_ 
expensive, but excellent quality (and worth it to restore an old HP
