It threads onto the inner wheel stud (3/4-16 internal thread) and has a 1-1/8-16 external thread to receive the outer nut, while the closed cap protects the stud end from corrosion and impact damage. Replace this nut when threads are stripped, corroded, or stretched, which can compromise clamping force and lead to wheel separation. Always torque to manufacturer specifications and inspect regularly.
