Abstract: An electrical ground strap assembly for an automotive vehicle. The assembly includes a carrier plate, a bolt having an incline portion, and a nut having an interior chamfer, the interior chamfer being oriented at an angle corresponding to the incline portion of the bolt. In use, the electrode is lowered onto the bolt and the nut is then lowered onto the bolt and the electrode. As the nut comes into contact with the electrode, the electrode is deformed therebetween to provide a mating fit between the incline portion of the bolt and the interior chamfer of the nut.

Abstract: A panel nut including an upper arm, a lower arm, and at least one transition arm extending between the upper arm and the lower arm to allow the upper arm to elastically deflect with respect to the lower arm is disclosed. The upper arm includes a forward flange, an inner member having a first end and an opposite second end, an outer member having a first end and an opposite second end, and a thread housing formed on the inner member. The lower arm includes a forward edge, an opposite rear end, a retainer hinge, and a retainer extending from the retainer hinge toward the rear end and toward the upper arm. The retainer is configured to elastically deflect between an unstressed position and a stressed position to be received within the thread housing when in the unstressed position.
