ZeeDix gauge set provides accurate measurement of wire, metal sheet, and welding rod thickness. It includes two stainless steel tools: a round disc and a rectangular gauge. Each has etched markings and slots for quick, precise sizing. The markings are in both metric and imperial units and are laser-engraved for long-lasting clarity. Simply insert the material into the closest slot—if it fits snugly, the size matches. A small faux leather case is included for storage.
