Wheel lug nuts and bolts are essential fasteners that connect the car’s wheel hub to the tires, ensuring stability and safety while driving. Different models of wheel lug nuts and bolts are designed to suit various types of vehicles, including passenger cars, commercial vehicles, and special-purpose vehicles. Typically, the nuts feature a conical seat, where the precise taper helps to create an effective fit with the mating surface, ensuring a reliable fastening force. Additionally, for anti-theft purposes, special nuts with unique patterns are usually paired with a matching socket wrench, and these sets are often sold with one wrench paired with four or eight nuts. In addition to functionality, various surface treatments and designs are available, offering more aesthetic options to meet appearance requirements.
For truck and agricultural machinery wheel hub bolts and nuts, there are higher strength requirements, typically manufactured to grade 10 or grade 12.9 specifications. Depending on the brand and model of the vehicle, as well as the material of the wheel hub, such as aluminum alloy, different designs are employed.
