Tap size - Shimano front derailleur adjusting screws
I picked up a nice set of Shimano MT-60 derailleurs for a Vintage Trek 600 Series off of eBay recently but when I received them one of the adjuster screws on the front derailleur was cross threaded. It is only the first few threads that are bunged up so I was hoping to be able to carefully and slowly work the adjusting screw in and out until the threads had been fixed up but this is not the case. Does anyone know the tap size for these small threads? I haven't been able to find it in the search.
