The DIN981 standard specifies the requirements for all-metal hexagonal locknuts, which typically utilize a pressure point mechanism to provide the locking function. Pressure point type locknuts have a metal insert inside and when the nut is tightened, the teeth of the insert are embedded in the threads of the bolt to provide locking. This design prevents the nut from loosening due to vibration.

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: Pressure point mechanism provides superior locking performance and prevents loosening. Increased Contact Area: The head of the nut is designed to increase the contact area with the workpiece, providing a stronger connection. DURABILITY: Made of high strength materials 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.
