Self-locking fastener features novel nylon insert(20/06/2012)
PEM nylon insert self-locking fasteners provide a reusable, non-metallic prevailing torque thread lock to prevent threaded mating hardware from loosening in service due to vibration or other application-related forces. Their novel blue nylon hexagonal locking element (black for metric types) eliminates potential galling, any need for lubricant, or the use of chemical locking methods or patches.
