Patent ID: 6868761

Claim:
A breakaway torque wrench system, comprising: a threaded member having a substantially circumferential outer surface and at least one axial groove defined in the circumferential outer surface; a polymer breakaway torque wrench comprising; a polymer arcuate engagement portion having an inner arcuate engagement surface, an angled flex portion, and at least one protrusion extending from the inner arcuate engagement surface, at least a portion of the inner arcuate engagement surface adapted to confrontingly engage a portion of the circumferential outer surface, and the at least one protrusion adapted to insertably engage within the at least one axial groove of the threaded member; a handle operably connected to the angled flex portion of the arcuate engagement portion; and wherein rotational movement of the engaged breakaway torque wrench correspondingly rotates the threaded member such that the angled flex portion correspondingly approaches the threaded member until a predefined torque level is reached causing the at least one protrusion to disengage from the at least one axial groove.
