Nylon locknut

• Locknut is a nut that resists loosening under vibrations and torque. Nylon lock nuts differ from a standard hex nut in that they have nylon insert secured within the nut. The nylon insert is located in a tapered section located at the back of the nut.
• When you install the nylon lock nut onto a bolt or threaded stud, the nylon insert wraps around the threads and locks the nut in place. This gives a nylon lock nut a distinct advantage over a lock washer when the bolt or threaded stud is subject to vibration, as the nylon lock nut is unaffected by vibration.
