PEMHEX® self-clinching prevailing torque locknuts from PennEngineering® integrate a trademarked blue nylon hexagonal insert designed to prevent mating screws from loosening in service due to vibration, thermal cycling, or other application-related factors. The reusable locking element provides the necessary torque resistance to securely grip mating screws and allow for their repeated installation and removal over time. The primary advantage of this locking method is to greatly reduce the possibility of conductive debris being generated from repeated installation and removal of mating screws. Thread-locking torque performance is equivalent to applicable NASM25027 specifications.(…)
