Internal and external tooth nuts, as the name suggests, have teeth machined on both the internal threads and the external surface of the nut. The internal threads are used to cooperate with bolts or other threaded fasteners, while the external teeth are used to cooperate with the corresponding locking elements (such as lock washers, locking tabs, etc.) to realize more reliable locking effects.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Material: Internal and external tooth nuts are usually made of high strength and corrosion resistant metal materials, such as stainless steel, carbon steel, alloy steel and so on. These materials can meet the strength and corrosion resistance requirements of different applications. Process: The manufacturing process of internal and external tooth nuts includes precision machining and heat treatment. Through the advanced manufacturing process, it can ensure that both the internal threads and external teeth of the nuts have high precision and excellent surface quality.

Scope of Application

Machinery and equipment: In machinery and equipment subjected to vibration or shock loads, internal and external tooth nuts can provide more reliable locking effect and prevent the nut from loosening and falling off. Automotive: In automotive manufacturing, internal and external tooth nuts are also often used for fastening of key components such as engine and chassis to ensure the safety and reliability of the vehicle. Furniture Manufacturing: In furniture manufacturing, internal and external tooth nuts are also used because of their unique locking effect, especially in the need to withstand large loads or the requirement of connecting parts of the beautiful occasions.
