What are Nylon Insert Lock Nuts?<\/strong><\/h2>\n

Nylon Insert Lock Nuts<\/strong>\u00a0(commonly called\u00a0Nyloc nuts<\/strong>) are a type of lock nut with a nylon ring insert that provides vibration resistance. When tightened, the nylon deforms against the bolt threads, creating friction that prevents loosening under dynamic loads. They are widely used in automotive, aerospace, and machinery where secure fastening is critical.<\/p>\n
