Hexagonal wrench for understanding direction of rotation

摘要

A conventional hexagonal wrench has a bent portion (3) between an elongated portion (1) and a short portion (2), and closes or loosens a hexagon socket head bolt. However, when the hexagon socket head bolt is attached to the lower side, the direction of rotation is reversed, and the direction of rotation may not be known in some cases. Therefore, the long portion (1) is bent so that the rotation direction of the hexagonal wrench whose direction of rotation is known is easily understood.SOLUTION: The hexagon wrench whose direction of rotation is known has a bent portion (3) between an elongated portion (1) and a short portion (2) of a hexagonal bar, and the center portion of the elongated portion Is bent in the range of 5 degrees to 45 degrees to provide the curved part (4).BACKGROUND OF THE INVENTION
