Title: Anybody out there who can retap theads?
Post by: Superkav on February 15, 2012, 10:33 PM: I've got a Hutch spindle with a bad thread that has just knackered the new button screw I tried to put in it. the other pedal was fine so I know the screws are good.

Anybody? I don't have a local metalworks that will do such a small job (not that 've found so far anyway)

Cheers

Post by: HUTCHMAN on February 16, 2012, 07:29 PM: i take it by using a button head screw your talking about the other end from the crank? 7/16 is .4375" ,just under 1/2 inch,prob more like 3/16(.1875,just over 4.75mm) but Animal is right,most likely UNC,or maybe UNF depending on thread pitch.
