Manufacturing Process of DIN 6923 Flange Nuts

DIN 6923 flange nuts are widely used in machinery, automotive, and structural applications because of their built-in washer design, which provides a larger contact surface and helps prevent loosening. To ensure consistent quality, the production process follows strict standards. As a professional flange nut supplier, XINCHI is pleased to introduce the manufacturing process of DIN 6923 flange nuts.

1. DIN 6923 Flange Nut Raw Material Preparation

High-quality carbon steel, alloy steel, or stainless steel wires are selected based on the required strength grade (8, 10, 12) and application needs, such as high strength or corrosion resistance. Using the right raw material ensures the final nuts are strong and durable.

2. Cold Heading Forming of DIN 6923 Flange Nuts

The wire rods are cut to precise lengths and formed into nut blanks using cold heading machines. This step shapes the hexagonal body and the integrated flange at the bottom. Cold heading not only improves dimensional accuracy but also strengthens the metal through work hardening.

3. Thread Tapping for DIN 6923 Flange Nuts

Once the blank is formed, internal threads are cut or rolled using tapping or thread-rolling machines. This ensures smooth and accurate threads that match bolts perfectly.

4. Heat Treatment of DIN 6923 Flange Nuts

Flange nuts go through quenching and tempering to achieve the required hardness, tensile strength, and fatigue resistance. This step makes DIN 6923 flange nuts suitable for heavy-duty and industrial applications.

5. Surface Treatment of DIN 6923 Flange Nuts

Depending on customer requirements, flange nuts can be zinc plated, nickel plated, black oxide treated, or hot-dip galvanized. Surface treatments improve corrosion resistance and provide a neat appearance for automotive and outdoor use.

6. Quality Inspection and Packaging of DIN 6923 Flange Nuts

Every batch is carefully inspected for dimensions, thread accuracy, and mechanical properties. GO/NO-GO gauges and torque tests ensure compliance with DIN standards. Nuts are then packaged securely for shipment.
