Ever hear of loctite or similar? All the benefits of ruined a stud's threads, without all the ruining!
With the proper preload, and then tightening of the poly lock, there really is not even a need for loctite let alone thread ruining.
Ha, thread ruining...

that's how an OE rocker nut works. its not pinched to the point that they destroy the stud, just enough to grab the thread. you install poly locks on studs that recently had fresh OEM nuts on them there is going to be some bite to it. the engine i have now, the last set of rockers were OE with new nuts. the stud thread had minor scoring from the fresh nuts. made the poly locks stay nice and firm in place
