What is a Lock Nut?
A Lock Nut is a type of fastener designed to resist loosening under vibration or torque. Unlike a standard nut, a lock nut includes a special design feature—such as a nylon insert, deformed threads, or mechanical interference—that prevents it from coming loose when subjected to constant motion or dynamic loads. Our dealing brand SKF Lock Nuts are widely used in machinery, automotive, heavy equipment, and industrial assemblies to ensure secure fastening in high-vibration environments.
