EzyWrench - Undo overtightened wheel nuts - 12 Volt
The unit is simple, robust and lightweight, operating from a 12v cigarette lighter connection or direct from a 12v battery
It produces a maximum torque of 340Nm (250Ft/Lbs) which exceeds most torque settings of wheel nuts
An average 4WD for example should have wheel nuts tightened to between 80 - 120Ft/Lbs. Usually over time wheel nuts become overtightened by heat, water, dirt & rust and require a true impacting action to loosen
A normal air gun at service station does not impact - it only rattles! See 'Operation' below!
The EzyWrench has been rigorously tested & used by many 4x4 clubs and organisations
