A lock nut is a fastener engineered to resist loosening under vibration and dynamic loads — conditions a working compact tractor generates continuously during operation. Unlike a standard nut, a lock nut incorporates a locking feature that maintains clamping force even as the machine cycles through load and vibration. A fastener that has lost its locking ability can allow connected components to shift or work loose, compromising the integrity of the assembly it secures.
