Lock nuts, also known as non-loosening nuts, are fastening components designed to prevent bolts from loosening due to vibration, shock, or repeated motion. They achieve this by incorporating a locking mechanism directly into the nut body, ensuring stable and secure fastening over time.
The loosening prevention mechanism varies by type and manufacturer and may include friction-based designs, spring elements, or nylon inserts. Each mechanism offers different characteristics in terms of reusability, resistance to vibration, temperature tolerance, and installation ease. This makes lock nuts suitable for a wide range of applications, including machinery, automotive assemblies, industrial equipment, and structural installations.
With MISUMI, users can choose lock nuts based on size range, material, surface treatment, and locking method, enabling precise selection according to application requirements and operating conditions.
