How to Prevent Bolts from Loosening Due to Vibration

Keywords: Bolts, FastenersVibration is the arch-nemesis of any bolted joint, causing even properly tightened bolts to gradually rotate loose. This micro-movement under transverse loads is a common failure mode. Solutions include using washers like spring or tooth lock washers, applying thread-locking adhesives, or specifying fasteners with prevailing torque features (e.g., nylon insert lock nuts). For critical applications, double-nutting or using high-strength bolts with precise torque control is advised.
