is the "torque" on mode 4 suitable for installing wheel lugs at a normal torque spec? What torque spec does it tighten to?

Mode 4 on the Hercules HCB85B does not have a specific torque value listed. Instead, in forward mode, it runs until a certain torque is reached and then shuts off to prevent over-tightening. It is designed to assist with installing fasteners like wheel lugs but does not provide an exact torque specification.
