The use of typical wrenches comes with the inconvenience of having to frequently change the head to suit the size of the bolt or screw head. In the cases where a bolt or screw has a hexagonal socket set into the head, we need to reach for an Allen key instead.
Double Wrench is compatible with both hexagonal and inner-hexagonal bolts and screws in a range of different sizes. It incorporates both hexagon spanners and socket wrenches. A mode dial is used to control the composite head. The required tool piece can be easily selected and activated. A labour-saving handle improves grip and turning force.
