Nylock nuts are inappropriate for use on high-temp assemblies. High-temp,
crimped-type locknuts are the right hardware for the this job. Nylon
plastic softens or melts at a fairly low temp, which defeats the entire
purpose of the locknut. I found stainless steel, high-grade, crimp-type
locknuts at Lowe's.
Also, 'too-long' bolts, stacks of washers (lock and/ or flat) is also
incorrect, especially for excessive exposed threads. This invites damaged
bolt end-threads due to exposure or corrosion, and will make subsequent
removal difficult to impossible.

I spend time (and money!) getting the right parts and checking installed
lengths for these very reasons. If you care enough to do it right, do it
right the first time, and you'll be glad later that you did!
This workmanship habit comes from years as a licensed aircraft/ jet engine
mechanic, both civilian and military.
