DIN 928 Square Weld Nut, Steel, Stainless Steel

DIN 928 is a square weld nut, steel and stainless steel, manufactured to the German quality standard. Materials: steel with a carbon content of no more than 0.25%, as well as stainless steel A2 and A4. The choice of material depends on the fastener’s purpose and application conditions. For mass production of fasteners, stainless steel A4 or A2 is typically used. Precise dosing of the steel composition is important for product quality: even a small increase in carbon content changes the metal’s structure, which is unacceptable for parts intended for reliable fastening of planes, assemblies and structural elements.

DIN 928

This is a universal square nut used in various industrial applications as a fastening element. It works in pairs with studs, bolts and screws. It is produced in different thread sizes, which broadens its range of application. In shape it differs from a standard hexagon nut: it is a square piece of metal with a threaded hole in the center, with a diameter from M5 to M8. On the top of the fastener there are four small projections at the corners — a characteristic distinguishing feature of this nut.

The DIN 928 nut differs from similar fasteners in its installation method. It is welded to thin-walled metal planes using capacitor discharge welding — including in cases where the wall thickness of the part does not allow a threaded hole to be cut into it. In this way, the weld nut solves the task of reliable fastening under such conditions.
