Abstract: A nut and retainer assembly for mounting an engine cradle to a vehicle frame. The assembly has a nut with a planar base and a hub provided with a threaded opening and a one-piece, spring steel, sheet metal retainer. The retainer has an apertured planar body, a pair of U-shaped channels along its sides and a pair of spaced deflectable tabs for loosely slidably receiving and retaining the planar base of the nut so as to have limited floating movement relative to the retainer. The retainer also has a deflectable third tab and a deflectable hand to enable it to be readily detachably connected to the vehicle frame.
