Nylon lock nut, also called a nyloc nut, is a hex nut with a nylon insert that creates friction against the bolt threads to prevent loosening under vibration or dynamic loads. The nylon insert allows repeated use while maintaining reliable locking performance. Nylon lock nuts are commonly used in automotive, machinery, electronics, and construction applications where secure fastening is essential. Available in carbon steel, stainless steel, and various finishes for corrosion resistance.
