    It’s a homemade nut driver, much easier to avoid over-torquing, and very compact. .

    You use the hand to tight it? what purpose the tape serves? i might need one of these.

    Yeah just hand tool.

    The tape (hockey stick tape) is grippy and it’s bulk gives you more torque strength.

    You can buy similar socket drivers; basically look like a screw driver. But they cost and they’re bulkier. If you’ve got spare ratchet extensions it’s something to try.

    for trivial locator bolts/screws this works just about right.

    All good advice, here is mine. Be very careful here. Use some solvent to soak into the threads, if you have a few days to do this even better. Take your time, if it even feels like the stud is going to break again stop. Having the stud break flush with the casting is not good, it can still be repaired but you may want to have it towed to a shop at that point. I have fought with stuck, overtightened and rusty hardware for a long time and several times had to punt and pay a professional to fix it. Now I have a MAP torch and a bottle of ATF, many times I do the heat/juice thing a couple times before even trying. Still bugger a bolt once in a while but not nearly as often.

    Here's my torque limiting device. Works with pretty much any ratchet. :D

    wrong tool for the job, using 1/2" click type torque wrench for bolts like these is way overkill and prone to errors since they are by default in ft lbs, there's a 1/4" click type torque wrench that is calibrated only for inch lbs. Heating it with a MAP torch will easily loosen that with vise grips or 2 nuts on top of each other could loosen this without using MAP torch.
