A wheel lug stud is the threaded fastener the lug nut tightens onto to hold the wheel against the hub. The serrated knurl grips its mounting flange so the stud stays put while the nut is torqued. Signs a stud may need replacing include stripped or cross-threaded threads, a stud that is bent or broken, or one that spins in its flange when the nut is tightened. Consult the vehicle service information for the correct installation procedure and lug nut torque.
