The GB6184/DIN981 standard defines the requirements for Type 1 all-metal hexagonal locknuts, which typically utilize inserted metal inserts to provide the locking function. This design combines the high stability of a metal locknut with the increased contact area of a flange nut to provide additional tightening and prevent loosening characteristics.

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:

Efficient Locking: The metal insert design provides superior locking performance and prevents loosening. Increased contact area: The head of the nut is designed to increase the surface contact area with the workpiece, providing a stronger connection. DURABILITY: Made of high strength materials, suitable for high load applications.

Scope of Application

Automotive industry: for the fixing of automotive components, such as wheel assembly, suspension systems, etc. Mechanical and Manufacturing: For fixing and clamping of components in the assembly of machinery and equipment. Architecture and Structures: For use in architectural and structural projects to ensure structural stability and safety. Pipe Connections: Commonly used to connect pipes and flanges, especially in applications where extra tightening and prevention of loosening is required.
