Wheel Screw

Wheel Screw (Wheel Bolt) is a critical safety fastener for heavy-duty trucks and semi-trailers. It firmly secures the wheel hub, rim and brake drum onto the axle, guaranteeing driving stability and safety under heavy load, long-distance transport and rough road conditions. Made of premium alloy steel with integrated quenching and tempering heat treatment, this wheel bolt delivers outstanding tensile strength, shock resistance and fatigue resistance. Precision thread rolling ensures excellent fitting accuracy and locking performance to prevent loosening or fracture during operation. Equipped with protective red plastic cap for thread protection during storage and installation. It serves as reliable OEM replacement part for commercial vehicle wheel assemblies.
