just stripped a m6 screw that holds on my ktm muffler. I obviously need to redo the threads to enable another m6 bolt to be utilized. easiest way is a helicoil. however on the muffler that will be removed a few times per year is the helicoil reliable enough? another option is a nutsert. trouble is I don't own the tool. can I install these nutserts with a rivet gun? give me insight into what would be the best solution given my situation. thanks heaps. apologies for no caps and not a wealth of info but the arm is in a cast and only have one finger typing at the moment.
