Never used these before a friend suggested I do. Worked great and that worry is now out of my mind.

    • Junk, the threads start very deep into the nut.
Ya get what ya pay for. I ended up buy some Comp rocker stud nuts. This may work for some piticular engine but not the small block Chevy I worked on.

    • Nice nuts
Appear to be well constructed, coating is nice and the threads were clean. Dont have a ton of miles on them yet but they assembled nicely onto the engine and all is good so far.
