Fastener-Tightened Bonnet Nut Wrench

摘要

A wrench adapted for use with bonnet nuts of shower valves. The present invention includes a substantially closed end wrench having a pair of disconnected distal ends separated by a gap. The distal ends each include a threaded aperture, each of which are aligned to allow a fastener to be inserted therethrough. As the fastener placed through the pair of complementary threaded apertures is tightened, it draws the distal ends together, thereby closing the head of the wrench. The present invention is used by placing the end of the wrench over the bonnet nut and then tightening the fastener in order to close the end of the wrench around the bonnet nut. The frictional engagement between the interior surface of the wrench end and the bonnet nut around which the closed end is tightened allows the user to apply torque to the wrench to tighten or loosen the bonnet nut.

主权项

1) A wrench, comprising:
a body; an arcuate member forming a substantially enclosed head with the body, the arcuate member comprising a distal end; a first aperture disposed on the distal end; a threaded second aperture disposed on the body; wherein the first aperture and the threaded second aperture are aligned such that a fastener is securable therethrough; wherein tightening of the fastener brings the distal end in contact with the body.
