Nylock Nuts (Nylon Insert Lock Nuts) are threaded fasteners with an integrated nylon insert that provides resistance to loosening due to vibration or dynamic loads. Installation involves threading the nut onto a corresponding bolt or screw until the nylon insert engages, creating friction that locks the nut in place.

Nylock Nuts are widely used in automotive, machinery, aerospace, and electrical applications where secure, vibration-resistant fastening is required. Available in various materials such as stainless steel and mild steel, they offer reliable mechanical strength, corrosion resistance, and long-lasting performance in both indoor and outdoor environments.
