Formulated to lock and seal fasteners without permanently bonding them, it eliminates the need to carry multiple lock nuts or lock washers and suits common automotive and mechanical repair tasks. The product cures on metal surfaces when exposed to air and provides reliable resistance to loosening caused by vibration across a wide temperature range.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Permatex 24240 keep bolts from coming loose during driving or operation?\u003c\/h3\u003e\n\u003cp\u003ePermatex 24240 fills the gaps between mating threads and forms a tough locking film as it cures, reducing the chances of fastener rotation under vibration.
