I beg to differ. Have used loctite products for many years. Nuts fixed
in place with loctite are easily broken loose. Studs can be double
nutted and broken loose, or in the case of thread problems, removed with
a stud puller. Loctite thread lockers, i.e. 242 or 271 for larger
fasteners, are intended to keep the fasteners from loosening with
vibration as does a nyloc nut or lock washer. Loctite used as intended
will not prevent later disassembly. John
