UNF All Metal Locking Nuts

UNF all-metal locking nuts are precision-engineered self-locking fasteners designed to provide secure, vibration-resistant fastening for Unified Fine (UNF) threaded bolts and studs. Unlike standard nuts, these all-metal locking nuts do not require nylon inserts, washers, or chemical thread-locking compounds. Their robust, all-metal construction ensures consistent locking performance, long-term durability, and reusability even in high-vibration, high-load, or temperature-variable applications.

At Arun Fasteners, we supply a wide range of UNF all-metal locking nuts in various sizes and finishes to meet industrial, automotive, and engineering requirements. They are ideal for precision machinery, automotive assemblies, aerospace components, and heavy-duty equipment, providing a secure fastening solution that minimizes maintenance while ensuring reliability. Whether you are assembling high-performance machinery or maintaining industrial equipment, our UNF all-metal locking nuts deliver strength, security, and long-lasting performance.
