What is Mexican Loctite?
1.
A substitute method of keeping threaded fasteners from becoming loosened due to vibration, stress, etc. Instead of using conventional liquid {loctite}, one simply assembles the fastener using dissimilar thread combinations, i.e., a coarse thread on on a fine thread bolt.
Alternatively, if the threads match, grind or hammer the threads of the bolt slightly to induce the crossthreading principle.
We didn't want the helicopter rotor to loosen unexpectedly, so we assembled it with Mexican loctite.
