Wheel Stud
A wheel stud is a threaded fastener that’s permanently mounted in a vehicle’s wheel hub or brake drum. It serves as the anchor point for the wheel, allowing a lug nut to thread onto it and secure the wheel to the vehicle.
Unlike a lug bolt (which combines the stud and nut into one piece), a wheel stud stays fixed in the hub. This setup makes mounting wheels easier: you simply slide the wheel over the studs and then fasten it with lug nuts. Studs are typically made from hardened steel to handle the high clamping forces and stresses from braking, acceleration, and cornering.
Wheel studs are standard on most cars, trucks, and commercial vehicles. They come in different diameters, lengths, and thread pitches depending on the vehicle’s design and are often replaced when damaged, stretched, or when longer studs are needed for aftermarket wheels or spacers.
