This 3/8" & 7/16" double ended ring spanner from Stahlwille benefits from both the quality of design and material used. This is why it conforms to the stringent standards of ISO 10103, assembly tools for nuts and screws as well as the German National Standard DIN 837.
With its short design and offset rings by 10°, it certainly delivers. With a compact length of 122mm, it will get the job done no matter how tight or awkward the working space is.
Made from the toughest chrome alloy steel, its chrome plated finish offers the protection it needs from oil, grease and water, as well as other chemicals and fluids, as well as helping you maintain a firm grip when you need it most.
