Lock Nuts are nuts that resist loosening under vibrations and torque. That’s why they’re used in automotive engines to reduce vibration, and hold wheels tight against the axles. Some lock nuts have a nylon insert, which help keeps the nut more snug against the bolt. Zoro has a super selection of nuts and bolts, including flange nuts, hex nuts, and wheel nuts too.
