Nylon Insert Locknuts

What is a Nylon Insert Locknut?

A nylon insert locknut (often referred to in the industry as a nyloc nut) is a highly reliable, specialized locking fastener equipped with an integrated, captive nylon ring at its top. When tightened onto a matching bolt or threaded stud, the bolt threads actively deform this nylon insert. This interaction creates a secure, high-friction grip that exceptionally resists loosening under all types of extreme vibration and dynamic torque, making them essential for high-movement machinery and automotive applications.
