Products Description
Our Carbon Steel ISO 21670 Hex Flange Weld Nuts are designed to provide a strong, secure, and cost-effective solution for applications requiring welded fastening points. These nuts feature a hexagonal flange that increases the surface contact area, providing superior grip and resistance to loosening under vibration or stress. Manufactured according to the ISO 21670 standard, they ensure a precise fit and reliable performance in industrial and automotive settings.
Made from high-quality carbon steel, these nuts offer exceptional strength and durability, capable of withstanding harsh environments and high temperatures. The flange is welded directly to the component, simplifying assembly and reducing the need for additional fasteners.

Products Process
Material Selection:
High-quality carbon steel, known for its strength and weldability, is selected as the base material.
Cutting and Shaping:
The raw material is cut into the appropriate shape, and the hexagonal profile is precisely formed through stamping or forging processes.
Flange Formation:
A flange is created, either as part of the nut or welded to the base of the nut, providing increased surface area for the weld.
Threading:
Internal threads are cut using high-precision machinery to ensure consistent thread depth and alignment.
Welding:
The flange is welded to the nut body using advanced welding techniques, ensuring a strong and durable bond.
Finishing:
The finished weld nuts undergo a series of inspections and quality tests, followed by surface treatment such as galvanizing or coating for corrosion resistance.
Final Inspection:
The product is tested for dimensional accuracy, strength, and thread integrity to ensure it meets ISO 21670 standards.
Products Application
Automotive Industry: Used for welding to car chassis and body panels where a strong, secure threaded connection is needed.
Construction Equipment: Ideal for welding onto steel structures to allow for easy attachment of bolts and fasteners.
Industrial Machinery: Used in machinery and manufacturing setups where welded fasteners are required for structural integrity.
Electronics & Appliances: Can be used for mounting and securing components in consumer electronics and home appliances.
HVAC Systems: Often welded onto ducts or metal components for securing parts in heating, ventilation, and air conditioning systems.
