Got a 3/8-16 threaded bolt on a hydraulic assembly that keeps working itself loose from vibration. This hex lock nut the right fix for that kind of thing?

Answer by: Customer Support on May 13, 2025, 6:24 AM

Vibration loosening is exactly what this nut is built to handle. The locking mechanism holds the connection under dynamic loads, so it won't back itself off the way a standard hex nut tends to do. For a hydraulic assembly that sees regular movement or pressure cycles, it's a solid choice.
