It is designed to press into a hub and provide a secure, vibration‑resistant mounting point for lug nuts on commercial trucks and trailers. Its serrations bite into the hub bore to prevent spinning or loosening in service. Replace it when threads are damaged, the stud stretches, or during hub or rotor service.
