DIN 929 hex weld nuts are widely used where a strong threaded fastening point needs to be permanently fixed to a metal workpiece. The hex body allows stable positioning during assembly, while the weldable structure makes the nut suitable for metal fabrication, machinery frames, automotive parts, industrial brackets, and equipment mounting systems.
This product is supplied in a metric thread system, with selectable thread sizes including M5, M6, M7, M8, M10, M12, M14, and M16. The broader model range is listed from M3 to M64, allowing buyers to match the nut size with different bolt and assembly requirements.
The confirmed strength grade is Grade 8.8, suitable for applications requiring dependable mechanical strength in industrial assemblies. Material options include carbon steel, stainless steel, and aluminum. Carbon steel is commonly selected for high strength industrial welding applications, stainless steel is suitable for applications requiring better corrosion resistance, and aluminum may be selected for lightweight assemblies depending on working conditions and order requirements.
Surface treatment options include plain, black oxide, and stainless steel finish. Black oxide provides a dark surface appearance and is commonly used for industrial hardware where a black finish is required.
