Integrate multiple protections: The combination nut forms friction locking, preload compensation and increases compression area through thread profile, conical washer and flat washer.
Achieve sealing; Pre-coated screws are locked and fixed by curing nylon/chemical adhesive, realizing anti-loosening, sealing and compression resistance synchronously, reducing the number of parts, adapting to complex working conditions, and improving assembly efficiency and long-term reliability.
