Tuerca de fijación hexagonal Plica PG21 poliamida gris claro GGM PG21 PA 6

The Plica GGM PG21 PA 6 is a high-quality hexagonal lock nut (counter nut) made from polyamide (PA 6) in light grey (RAL 7035). Designed for PG21 threaded connections, it securely fastens cable glands, conduit fittings, and other threaded components in electrical and industrial installations. Its robust construction and excellent chemical resistance make it suitable for demanding environments.

Advantages

This lock nut offers reliable locking performance, preventing loosening due to vibration or thermal expansion. The polyamide material provides electrical insulation, is halogen-free, and has a UL94-V2 flammability rating. It is lightweight yet durable, with good resistance to oils, greases, weak acids, and alkalis. The hexagonal shape allows easy installation with standard tools.
