Abstract
A deformable wrench for applying torque to a nut engaging a threaded fastener includes a wrench body having a center portion with at least one wing portion extending therefrom. The wrench body is formed from an elastic material and a socket aperture extends through the central portion between spaced upper and lower surfaces thereof. The socket aperture is configured to cooperate with the profile of the nut to permit rotation relative to the fastener by applying force to the wing portion of the wrench. At a predetermined torque value, the walls of the socket aperture deform to permit rotation of the wrench relative to the nut thereby preventing over-torquing the nut on the fastener.
