Lock nuts like these degrade if hot. Otherwise they are amazingly good. They don't loosen, they are reusable a few times and they are reasonably priced.Remember they require additional torque to set. Otherwise, they work incredibly well.

I like the eas of starting the fine thread bolt with a few threads before the nylock starts .
