Loctite vs. various lock/split washers vs...... epoxy??
I dunno why anyone would want to mix and apply 2-part products when Loctite
formulas will do an excellent/proven job.
Numerous fasteners are available with an epoxy-type product already applied
for numerous applications from nails/staples to more heavy duty steel
fabrication fasteners.. generally considered OTU one-time-use permanent
fasteners, not removed for maintenance/service.
Screws and nuts are available as nyloc types which will essentially insure
that the fastener won't separate from vibration, such as a nyloc nut mounted
on a screw acting as a pin, but I dunno about (doubt) the effectiveness at
maintaining a specified torque.
The mil-spec and aviation self-locking nuts with synthetic inserts may hold
to a specified torque when used as specified for one-time-use only.
To insure that a nut doesn't come off with general hardware, the screw
threads can be distorted/smashed after the nut's in place to ensure that the
screw will need to be broken to separate the pieces.. or use stainless steel
for intentional gall/seizing of the threads.
And rust is still considered fairly effective.
As far as a "little heat" being effective at loosening epoxied hardware (or
red Loctite), a soldering iron may be useful for small fasteners up to maybe
1/8" but not enough heat for anything larger, assuming the heat can be
applied to a nut on a screw, not heating a screw length imbedded in
heat-sinking material.

Iffin you REALLY wanted to be sure that a nut won't fall off a screw, or a
screw will loosen, wouldn't plain ole 2-part epoxy be the best bet?
Also, if an epoxied screw/nut did have to come off, wouldn't a little heat
do it?
