Lifesavers. I have some bead lock wheels with a couple of threads that were stripped out on the locking ring. Installed a few Helicoil’s and the rest is history. Back n the race!!

these are one of the best and most useful thing you can have in your tool box if you work with Alluminum you just about have to keep them in all sizes.
