1. A torque wrench, comprising:
a handle extending along a longitudinal axis and configured to be grasped by a user;
a head configured to rotate a fastener about a rotational axis, the head comprising:
a first side;
a second side opposite the first side;
a ratchet mechanism including a through bore, the rotational axis extending through the through bore; and
a drive arbor that extends through the through bore, the drive arbor comprising a first end and a second end opposite the first end along the rotational axis;
a primary beam coupled to the handle and the head;
a secondary beam coupled to the head and selectively coupled to the primary beam;
a torque adjustment mechanism that moves the primary beam relative to the secondary beam, the torque adjustment mechanism comprising:
a rack gear; and
a gear coupled to the rack gear;
wherein the ratchet mechanism couples the drive arbor to the handle for rotation about the rotational axis in a first direction and allows the handle to rotate relative to the drive arbor in a second direction opposite the first direction; and
wherein both the first end and the second end of the drive arbor are configured to engage the fastener.
