Introduction of wheel nut

A wheel nut is a critical fastener used to secure automotive wheels. It is typically paired with a bolt to ensure that the wheel is firmly mounted onto the hub. As a safety-critical part, wheel nuts play a vital role in ensuring the safety and stability of vehicles during operation.

Material Selection

Commonly used materials are high-strength alloy steels such as 35CrMo and 40Cr, which, after strict heat treatment, provide excellent mechanical properties and fatigue resistance.

Manufacturing Process

• Multi-station cold forging: Ensures product strength and consistency
• Turning & threading: Improves dimensional accuracy and thread precision
• Heat treatment: Enhances hardness and service life
• Surface treatment: Improves corrosion resistance
• Packing & delivery: Safe shipment according to customer requirements

Surface Treatment Options

Depending on application requirements, various protective coatings are available:

• Zinc plating
• Dacromet coating
• Electrophoretic coating
• Phosphating
• Anti-rust coating
