This tool is perfect for fixing threads that are moderately to severely damaged but still there. It can be used whenever the exhaust nuts are removed to clean and reshape the threads. This is a must have tool for any serious airhead mechanic.
It happens quite often that the exhaust nuts were at some point over tightened of not installed with copper paste or anti seize and they get stuck. Before forcing the issue and ruining the threads entirely, stop and cut the old nuts off. Even then, some damage will have likely occurred to the threads but this tool will save the day (and the head) in that case..
Size= M48 x 2. Suitable for all R45 and R65 65 models.
