Kyoto Tool Hex Wrench M274 (KTC) Set, 4-Piece Set,

Product model number: M274 Set contents: M27-8H, 10H, 12H, 14H The hexagons are angled symmetrically at 15 degrees, allowing for the same work as a twelve-sided wrench (30 degree swing angle rotation). The handle is angled at 45 degrees x 10 degrees, making it easy to apply force and providing a comfortable grip that fits comfortably in your hand. The chamfering of the hexagonal bore has been eliminated, increasing the contact area between the bore and the bolt/nut.
