Self-locking nuts

Design and operation of self locking nuts

Self-locking nuts are indispensable fasteners that ensure reliable and safe connection of parts even in extreme conditions. They are specially designed to prevent self loosening under vibrations and dynamic loads. Due to their unique design, self locking nuts remain securely fastened, ensuring the stability and safety of structures.

Self-locking nut sizes

Self-locking nuts are available in a wide range of sizes, allowing them to be used in a variety of industries and for different purposes. They can be made from a variety of materials, including stainless steel, carbon steel, and other alloys, which ensures their high strength and corrosion resistance. Self-locking nuts can range in size from small, such as M3 or M4, to large, such as M30 or even larger. This allows them to be used in both lightweight structures and heavy industrial connections. Regardless of the size, all self-contracting nuts have a common characteristic - they effectively prevent loosening and ensure the stability of the connection under the influence of vibrations and other dynamic loads.

Self-locking nut: manufacturing process 

Self-locking nuts are manufactured using a complex technological process that ensures their reliability and durability. First, high-quality steel is selected and subjected to rigorous quality control. Then the steel is cut into billets of the required size. The billets undergo a cold stamping process to shape them into the required shape. The nuts are then heat treated to provide them with the necessary hardness and strength. At the final stage, a special coating is applied to the inner surface of the nut or a nylon insert is embedded to prevent self-tightening during operation. Each batch of nuts undergoes quality control to ensure compliance with the established standards.
