The Campy 649 brake cable clips... anyone know what the screw threading is on these? I was going to replace the screws on mine with some stainless, but can't figure out the threading. Not M3, not 4-40. The thread looks to be a bit coarser in pitch than an M3, but about the same diameter. The hardware store I was at did not have any M3.5.
From old catalogs, they show the nut as a separate piece, but mine are captive. I'm not sure I've ever seen any that aren't. I posted this on C&V, but no one seemed to know.
