I have a 6800 series Ultegra front mech that has three bolts for adjustment. The High and Low setting and the Support Bolt. All three bolts are turned using a 2mm allen/hex key. I need to replace one of these bolts - not sure at this point if Shimano do a replacement part but wondering if I can just buy a equivalent bolt. Does any know the thread dimension of said bolts? Thanks.

    OK - from what I've found out these screws/bolts are M4 x 8

    I am sure if they are m4 the pitch is a standard 0.7 mm, so an equivalent m4 Allen headed screw will fit
