FWIW, I retired from Chevron after 28 years. Worked in three of their
oil refineries and
the last 7 years at their Research Center in Richmond, CA.
On mechanical fasteners used on vibrating machinery, pumps, compressors,
etc. Red locktite
was the standard along with proper torquing. It should be mentioned in
this discussion that
you should find the correct torque specification and use a torque wrench
to tighten the
bolted connections too. Red locktite and proper torquing should give
you positive results on all
but the most severe connections. Having said that, I am impressed with
the NordLock washers
and am trying them out on my Orion 2800. From what I learned they should
be the ultimate in locking.
I will report back in about 10 years and let you know how my OR 2800
bolts are doing. :-)

For you, or us on a small scale (and time to make sure the bolts are
clean), it may be, but apparently for industry, it's not.

## say what ? Blue loctite is used all the time in the automotive
and race car world. Put blue
loctite on the 6 x .375 SS bolts that hold an OR-2800 rotor to
the rotor plate...and you wont be
having bolts coming loose anytime soon. I used blue loctite in
loads of places on my Roush mustang,
nothing comes loose... including the new one piece AL
driveshaft..which spins at 6500 rpm.
Plenty of local folks here in town also use Red loctite for
automotive applications.
Purple loctite is weaker than blue loctite, and is another
alternative. Red is the strongest.
## I would not use red loctite for small stuff like machine screw
size.... otherwise you will never get em out, they will
be as good as welded into place.
## UST uses nylocks for all 22 pulleys used on my HDX-689.
Non of them loosen up. Between nylocks and
blue / purple loctite, you are covered.
