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.

Deformable wrench

A boot for an antenna assembly is disclosed. The antenna assembly includes an antenna mast having an antenna mast nut attached thereto, a tubular housing extending through an aperture in an automobile body, and a center conductor having a threaded stud attached at one end thereto received by the housing. The antenna mast nut is attached to the threaded stud, and an isolator is disposed between the housing and the center conductor. The boot includes a disk-shaped base member having a cylindrical recess and a first diameter formed from a lower surface thereof and a cylinder-shaped projection extending upwardly from an upper surface of the base member. The projection includes a bore having a second diameter smaller than the first diameter formed therethrough. The base member is operable to seal an upper surface of the isolator, a side surface of the isolator and an outer surface of the housing. The projection is operable to seal an outer surface of the center conductor.
