KING TONY 1/2″ Drive 21mm Wheel Nut Impact Socket | 493521M

The KING TONY 493521M is a 21mm 1/2″ drive impact socket intended for wheel nut fastening and removal. Its impact-rated construction makes it suitable for use with compatible powered impact tools during tyre, wheel and automotive service work. The 21mm working profile fits a common wheel nut size, while the dedicated wheel-socket format provides a practical solution for workshops, tyre fitment centres and technicians performing frequent wheel changes. A secure socket-to-fastener fit helps transfer impact torque effectively during removal and installation. As with all wheel fastening, final tightening should be completed to the vehicle manufacturer’s specified torque using an appropriate calibrated torque wrench rather than relying solely on an impact tool.
