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
