scs problem

[CJ Treihart]

my bolt is stripped my 4mm allen key is to small now and my 5mm is to big i need help to get this bolt off with sawing it off

if the bolt sticks out enough on the other side, then cut a slit in the tip and unscrew it with a flat head screw driver. or get a pair of needle nose pliers and unscrew it from the slit in the knuckle
