what exactly does stretch sound like? I am a dumb**** for using a torx in the first place. the inside of the stud is stripping, losing metal, becoming unturnable. they all mostly turned fine without any noise. I had four of them at the final 90 degrees. torqued down to 40lbs, one 90 deg, another 90 deg. the chasing of threads went fine. the tap came out smoothly everytime with no metal. I am just using the wrong tool for the job. I will just order some new ones and replace the ones that stripped. hopefully the gasket will be fine after compressing and decompressing and compressing it again.
