Hollow Bar with 0.5 Inch ( ½" ) Threaded Outer. Although M10 x 1 Fine is the "Electrical Norm" these days in both UK and Europe, the traditional size was 1/2". We keep only 2 sizes of 1/2" thread in stock now and they are both in brass, as most people using it really are working on keeping the restoration original.
