The pipe wench includes a first jaw coupled to the head having a plurality of teeth defining a first contact region, and a second jaw partially extending through the aperture of the head having a threaded portion and a plurality of teeth defining a second contact region. The second contact region extends beyond the first contact region in a direction parallel to side surfaces of the head. The pipe wrench includes a biasing mechanism located within the first aperture to align the threaded portion of the second jaw with the central axis of the first aperture, and an actuator having threads engaged with the threaded portion of the second jaw such that rotation of the actuator moves the second contact region of the second jaw relative to the first contact region of the first jaw.
