McMaster 5314A99 Polished Chrome-Plated Combination Wrench with 12-Point Openings, 15-Piece Metric Set

Made in the U.S.A., these tools handle the toughest industrial applications, provide the best grip on fasteners, and have a superior finish. Wrenches with a 12-point opening are easier to position on hex fasteners than wrenches with a 6-point opening but make less contact. Polished wrenches have a mirror-like finish.
