A speed wrench includes an open end having a through portion connected to a shank of the wrench and a first jaw and a second jaw respectively extend from the throat portion. The first jaw has a first flat surface defined in an inside thereof and the second jaw has a second flat surface defined in an inside thereof. A throat recess is defined in the throat portion ad a first recess is defined in the inside of the first jaw, and a second recess is defined in the inside of the second jaw. An end of a periphery defining the second recess is connected to the second flat surface and a 60-degree angle recess is connected between the other end of the periphery of the second recess and the throat recess. A first pushing side is connected between the first flat surface and an end of a periphery defining the first recess. A second pushing side is connected between an end of a periphery defining the throat recess and the other end of the periphery defining the first recess. Four sides of a hexagonal object contact the first pushing side, the second pushing side and two sides composing the 60-degree angle recess.
