The DIN 985 standard specifies the requirements for all-metal hexagonal locknuts, which usually utilize a nylon insert to provide the locking function. A nylon locknut is a nylon ring with an inside diameter approximating the small diameter of the thread embedded in the top of the nut, which is secured by riveting. This design utilizes the friction between the nylon element and the bolt threads during tightening to increase resistance to loosening.

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.
