DIN 928 Square Weld Nut

Professionally tailored for pre-weld fixing and integrated forming assembly, Wanluo’s high quality DIN 928 Square Weld Nut are manufactured strictly according to German industrial standards. Unlike conventional fastening nuts that rely on post-installation locking, this series of weld nuts adopts a square integrated structure with precise welding projections, enabling accurate positioning and spot welding fixation on metal plates and profiles.

Product Description

DIN 928 Square Weld Nut by Wanluo supplier solves common industrial problems such as inaccurate manual tapping, unstable nut welding offset and low assembly efficiency, providing one-piece threaded base forming solutions for automated production and sheet metal processing.

Structural Design & Welding Stability

DIN 928 Square Weld Nut feature four-sided flat positioning and integrated welding bump design. The uniform welding projections ensure consistent melting degree during spot welding, forming firm fusion connection with the workpiece without virtual welding or desoldering. The standard vertical internal thread is processed by high-precision one-time tapping, with complete tooth shape and precise tolerance, ensuring smooth subsequent bolt matching assembly. Made of high-quality stainless steel raw materials, the product has uniform metal texture, strong welding high-temperature resistance and structural stability, and will not deform or loose thread accuracy after welding and cooling. It effectively improves the overall structural strength and assembly consistency of batch production workpieces.

Core Application & Process Advantages

1. Integrated welding projection design realizes accurate positioning before welding, effectively preventing nut deviation and rotation during welding, greatly improving the yield and consistency of batch workpieces.

2. Replace traditional manual tapping and post-installation nuts, simplify production processes, eliminate thread slipping and tapping failure problems of thin plates, and significantly improve production efficiency.

3. The DIN 928 Square Weld Nut square limit structure has good anti-rotation effect after welding and forming, with uniform stress on the thread base, effectively resisting vibration load and avoiding loose connection in long-term equipment operation.

4. Stainless steel material has excellent high-temperature welding performance and corrosion resistance. The welding joint is firm without rusting, adapting to automated equipment, sheet metal shells and outdoor metal structural parts.

5. Suitable for assembly scenes that cannot be locked by traditional nuts and rivet nuts. It realizes permanent fixed thread base and is widely used in automobile manufacturing, electrical cabinets and engineering machinery.
