Hello F-16:

If all else fails get some BLUE Loctite from an auto parts store. Put a very small dab on the treads and install your nut. Do not use anything else, Red will stick that darn nut on permanently and any other will not have enough stick to help you. I also do not use regular nuts and washers on spinners. I use a Higly nut (saftey nut) and have vever had this problem. I wish you the best.
