I don't think so. This sounds like a critical application to me and while
nyloc nuts are reusable, the Bowman tech manual states that "these nuts
(nyloc) are limited in thier reuse as compared with all-matel prevailint
torque-type lock nuts. . .When reused the prevailing-on torque can be as much
as 60% less than the initial prevailing torque resistance. Therefore
vibrational resistance is greatly reduced. They are NOT for use with
high-strength fasteners unless specially marked with grade markings. .
.Neither grade can be used in elevated temperatures above 250 degrees F as
the nylon softens, or will melt, reducing locking effect." I think if I am
working on a critical part, that if it failed would absolutely wreck me, I
would go with stock or better. Nylocs are not better.
Just my loose change on the subject (with an informed interject by Bowman).
