Snap-on's10-Piece Metric Flank Drive Plus combination wrench set and the 7-Piece Fractional Flank Drive Plus combination wrench set are constructed from a special alloy steel, cold broached for durability and heat treated for hardness, allowing the wrench to bend in situations where other wrenches will break. Flank Drive Plus grab fasteners on the flats, instead of the edges for more power. Also, the 15° offset end helps with clearance problems and tight spaces. Nickel-Chrome finish provides high-shine and resistance against corrosion and wear.
