groupset has several non-standard length screws in it. And of course
they're the ones that screw into blind holes... I wanted only to
replace four crossheads with hex socket heads, but i spent the entire
afternoon filing the bolts to length.

That assumes you're only taking a bit off - more than a few mm and a
hacksaw is the correct tool. Leave a nut or two on to clamp to and tidy
up the threads afterwards.
Thanks, Clive. I don't have a problem working out such simple
procedures -- I used to build one-off cars from scratch, and turned
several old Bentley into sports cars. But it takes me a while to
assemble all the tools from various places; I don't keep a tap and die
set in my bike toolbox, for instance.

bolt head, for example on a rack mount to keep the end of the bolt out
of the chain.

Sure, I add plain and spring washers routinely where there are none,
but in this case the plastic part was indented and the hole only big
enough to hold the socket head, no space for washers.
I really cannot understand how a firm like Shimano can order a special
length screw rather than redesign the plastic fitting to use a
standard length screw; in fact, I fail to understand how they so
misdesigned it in the first instance. I dropped one of the originals
and it was gone. That could be very irritating to some poor sod
without the tools or the time to shorten a locally available screw,
not to mention that sockethead screws are available only in a limited
range of sizes at a single hardware store in a fifty mile radius (he
got them in for me for something else). It isn't either as if the
wretched little brown plastic part will be aesthetically ruined by
being made half a millimetre thicker.
