A method and apparatus for securing non-load bearing interior walls in a wood frame structure in a manner that allows for vertical deflection of the frame includes a plurality of sleeved fastener assemblies, each having a threaded fastener extending through a shorter outer sleeve with an enlarged diameter head. The fasteners hold interior non-load bearing walls in place through a predrilled hole in the top plates of the walls, while being capable of accommodating limited vertical movement caused by vertical deflection of the building frame during construction and beyond.
