Best 10 Disc Nut Factory in China 2025

Introduction to Disc Nut

Disc nuts, also known as Belleville washers or conical spring washers, are a type of spring washer with a conical shape. They are designed to provide a high load capacity in a relatively small space. Disc nuts are commonly used in applications where a high degree of pre - loading is required, such as in bolted joints in machinery, automotive engines, and aerospace components. Their unique shape allows them to exert a constant pressure on the joint, compensating for any relaxation or expansion due to temperature changes, vibration, or other external factors. This helps to maintain the integrity and reliability of the connection over time.
