Ted:

I'm with you, pal. Valve caps do seem to be yet another example of a solution in search of a problem.

At least the "dork nuts" can be pressed into service here and there. I've used them to hastily fit a pair of mudguards recently without having to remove the fixing nut on brake caliper centerbolts because the threading matches. I've also had occasion to ream out the threading with a chainsaw file and use them as bushings to mount a pair of conventional nutted brakes to a frame set up for recessed mounting. After removing threading and enlarging the ID a bit, they can also be used as spacers to fit a front brake caliper to a rear brake bridge by stacking out to the threaded portion so the fixing nut can grab. Definitely a bit of a bodge but it works and saves one from having to remove the chroming, run a die over the unthreaded portion and cutting to length.

Any other examples out there for adaptive reuse of those little knurled nuts?
