Nylock Insert Lock Nut

Nylock Nuts (Nylon Insert Lock Nuts)

Our Nylock Nuts are engineered to solve the critical issue of fastener loosening caused by vibration and dynamic loads. Featuring a durable nylon insert within the collar, these nuts grip the mating bolt threads tightly to create a high-friction seal that acts as a locking mechanism. Unlike standard nuts, they do not require lock washers and provide a secure, vibration-proof hold, making them indispensable for automotive, aerospace, and heavy machinery applications.
