• does anyone have a m18 thread tap? i want to extend an existing thread deeper into the material for use with a longer bolt having rounded the first 2/3 of thread on the axle of some fancy fsa cranks. all a little bit last ditch and hopeful at the moment.

  • i don’t know much about threads and can’t say the tpi but the bolt it takes is fairly standard for fsa, both kinds i have bought have fitted. can’t believe i was so stupid to round this in the first place,
