DOUBLE OPEN END SPANNER SET 6-27MM 10PCS/6-32MM 12PCS

Built for daily workshop use, these YATO double open-end spanner sets combine durable chrome vanadium (CrV) steel with a comfortable satin finish and polished heads for smooth positioning on fasteners. Made to DIN 3110, they’re a reliable choice for mechanics, maintenance teams, installers, and DIY users who want a practical size range in a compact set.

Both sets feature HRC 42–48 hardness for a strong balance of toughness and wear resistance, helping the jaws maintain shape under typical service loads. The satin surface improves grip and reduces glare under workshop lighting, while the polished heads help the wrench seat cleanly and move easily around bolts and nuts.
