It is a hex nut with a nylon collar insert that grips the threads of a mating bolt or stud to resist loosening from vibration. These are commonly used throughout heavy-duty trucks and trailers on suspension, chassis, and accessory mounting points where a reliable, reusable locking fastener is needed. The nylon insert creates friction that helps keep the nut tight even under constant shaking and load cycles.
