Locking Nylon Insert Nuts are threaded hex nuts that include a nylon insert, which compresses around the mating bolt threads to resist vibration and loosening.
Available in steel (with finishes like zinc, yellow zinc, or zinc flake) and corrosion resistant stainless steel, we offer both coarse and fine thread versions as well as variety in body heights and styles.
Designed to preserve the bolt threads and maintain reliable locking performance, these nuts are great for equipment exposed to movement or vibration. Browse through styles like flange, lowāprofile, and highātype lock nuts to find the right fit for your project.
