The Wiha 'T' handle nut driver is designed to provide high torque transmission from hand to nut or bolt. It is particularly useful when maximum tightness is required or when removing a bolt is proving difficult. The handle is moulded directly onto the blade and under normal use is inseparable. Accurate hex recesses with deep hollow to allow long threaded sections to be overcome. Blade length 125mm, hard chromed for extra life.
