Combination Wrench Set, 41-Piece (1/4 - 1-1/4 in., 6 - 32 mm, Common Sizes)

Each Tekton combination wrench is permanently marked with a stamped size marking on both sides for easy identification. The 12-point box end doubles the available access angles compared to a 6-point end. It is designed to contact and apply force to the sides of the fastener head rather than the corners, helping to prevent round-off. The 15-degree offset box end creates clearance for your fingers and makes it easier to reach around obstructions. To reduce the working swing arc in tight spaces, the open end is angled 15 degrees so the wrench can be flipped over with each rotation to engage the fastener twice as often.
