Hi all,

For some of the dimensions where I don't have proper taps, I've long kept a set of screws/bolts with a notch cut through the threads to clean out grimy and mildly damaged threads.
Considering the entirely marginal cost, they've worked OK.
But I'm thinking of buying some proper taps. Steel-on-steel cleanup performance kinda sucks.

Current considerations:

-derailer hanger thread, M10x1.0
-Square taper crank bolt, M8x1.0

I'm figuring these to be so close to normal that cost-per-use doesn't get prohibitive even for my mainly own-use purpose.

Wasn't planning on going for BB shell taps, but maybe a set of pedal taps.

I'd be glad to take recommendations on other taps as well as where to get them (a pre-Ebay search question...)

Cheers,
