UNC All Metal Locking Nuts

UNC all-metal locking nuts are precision-engineered fasteners designed to provide reliable, vibration-resistant fastening for Unified Coarse (UNC) threaded bolts and studs. Unlike standard nuts, these all-metal locking nuts do not rely on nylon inserts, washers, or chemical thread-locking compounds. Their durable, all-metal construction ensures long-term, reusable locking performance even in high-vibration, high-load, or temperature-variable environments.

At Arun Fasteners, we offer a wide selection of UNC all-metal locking nuts in various sizes and finishes to meet industrial, automotive, and engineering requirements. Perfect for machinery assemblies, automotive projects, heavy equipment, and structural frameworks, these nuts deliver a secure, maintenance-free fastening solution. Their consistent locking action and robust design make them the ideal choice where safety, reliability, and durability are essential.
