Are you talking about the wheel hub with the five studs that the wheel bolts to? This has a castellated nut that secures it with two cap screws. The locking nut is torqued to 542 NM (400ftlb). As long as you haven't removed the wheel hub you should be ok as it needs to be heated to 200 degrees C (400f) before fitment and the nut immediately fitted to the correct torque.
