Abstract

Abstract A leveling foot assembly for a laundry appliance, such as a washer, including an internally threaded T-nut attached to each corner of the bottom of the housing and a T-nut support having a flat head portion welded on the inner surface of the panel on the opposite side but concentric with the head of the T-nut. The Tnut support has a cylindrical sleeve defining one portion which circumferentially engages the cylindrical stem of the T-nut extending through the panel, and a terminal portion having a circular opening of a diameter less than the outer diameter of the threaded footbolt received within the T-nut. Thus, the T-nut support, in addition to providing lateral support for the T-nut interferingly engages the threads of the footbolt and prevents its turning unless delibrately done so with a tool.
