Not sure how a Nylock nut applies for ICS????
A Lock washer on the ICS Bolt will work
Locktite- is basically Glue, so it helps keep the Bolt from vibrating loose from the Starnut in ICS or a regular Nut in other applications.
"Threadlockers are a single component anaerobic adhesive comprised of unique liquid resins that harden (or cure) to a durable solid when exposed to metal ions in the absence of air. The anaerobic cure mechanism allows the adhesive to flow and evenly settle to lock and seal threaded fasteners without curing permanently. Any excess threadlocker will remain liquid, and is easily wiped away from the assembly."
