DIN 928 is a German industrial standard that specifies requirements for dimensions, materials, mechanical properties and test methods for welded square nuts. These nuts are designed for fixing to sheet metal by welding and are suitable for applications where a strong connection is required and dismantling is infrequent.

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:

Welded fixing: Fixed to the metal plate by welding to ensure a firm connection. Anti-loosening: Welded connections prevent the nuts from loosening during vibration. Space-saving: The square design allows the nut to be used in limited space.

Scope of Application

Sheet Metal: Used in the welding fixing of sheet metal, frames or mechanical structures. Automobile manufacturing: Used in the fixing of automobile seats, seat belts and other components. Mechanical equipment: For use in welding parts of mechanical equipment to provide a solid connection.
