Nylon Insert (Metric) Locknuts

Nylon Insert (Metric) Locknuts, also called Nyloc Nuts, are a type of hex locknut featuring a nylon insert at the top of the threads, creating a tight grip on the bolt or screw. This grip helps to prevent the fastener from loosening due to vibration or other external force. Nylon Insert Locknuts are a versatile and reliable fastener option well-suited for a wide range of applications with a secure connection.

Nylon Insert Locknut Industrial Applications

Because Nylon Insert Locknuts are versatile with excellent fastening strength, they are used in many industrial applications. The internal diameter of the nylon material in the collar is slightly smaller than the nut thread’s minor diameter. Once the external threads of the mated part come in contact with the Nylon Insert Locknut’s nylon collar, a tight, frictional fit is created between the threads, thus restricting the loosening of the fastened parts under vibrational forces. This resistance to loosening due to vibration makes Nylon Insert Locknuts popular fasteners for automotive, construction, mechanical, manufacturing, and many more industrial applications.
