An adjustable gripping tool including an adjustable opening to grip and impart work or a rotational force on work pieces (e.g., nuts and bolts) of various sizes is provided. The gripping tool of the present disclosure includes a ratcheting configuration and an adjusting configuration and can change between each configuration. While in the adjusting configuration, an adjusting bolt may be rotated to cause a plurality of jaws or gripping members to converge toward each other or diverge away from each other to adjust the diameter of the opening of the gripping tool. In this way, the plurality of jaws may converge onto work pieces of various sizes to grip the work pieces securely in the opening. The gripping tool may then be changed to the ratcheting configuration. In the ratcheting configuration, a handle of the gripping tool may be gripped and rotated to impart work on the work piece.
