Nylok coating works well up to about 121°C. Beyond that, nylon may soften and lose locking force. For higher temperatures, choose a metal lock nut or other locking method rated for your conditions.
You can reuse it a few times, but friction decreases with repeated use. For critical assemblies, replace nylok-coated nuts after removal to ensure proper locking performance and avoid joint loosening.
Compare assembly process and environment. You use nylok coating for reusable joints and moderate temperatures. You use adhesive where you need higher temperature resistance or when disassembly is rare. Evaluate torque specs and service needs before deciding.
