Stahlwille Inch double open end spanners, 1/2" x 9/16"

The spanners are Chrome Alloy Steel, chrome-plated. The spanners are drop-forged, hardened and cooled in an oil bath, with a double-T profile for bending strength, a round finish for grip and a reinforced transition from jaw to shaft, where the highest forces act (Offset Shaft Design).
