I used to think fastners used in our hobby are not available locally. But recently I found that they are. I bought a few mounting bolts for my OS FS91 at a local hardware store. Then the muffler bolts on my old 55ax became unuseable as they wouldnt turn with any of my allen keys. The 3mm variety available in the store was too short so I purchased a pair of 3mm cheesehead bolts and they went in fine (will need to put on locknuts though)

Just one question, if I put in locktite, will I be able to open the bolt later when I actually need to? So far I have always used the locknut technique to prevent this, but I am not sure I can use the locknuts on the 55ax stock muffler as there may not be enough space
