Abstract: A method is provided for the projection electric resistance welding of a component to a laminated metal member. The laminated metal member is comprised of top and bottom metal sheets adhered together by a polymer layer provided between the top and bottom metal sheets. A plurality of projections is provided on the component and the projections extend toward the top metal sheet of the laminated metal. Force is applied to the component and the projections have a pointed shape so that the projections pierce through the top metal sheet and contact the bottom metal sheet. Weld current is then applied to flow through the projections so that the projections are electric resistance welded to both the top and bottom metal sheets.

Abstract: An improved cage nut assembly is comprised of a cage, a pair of slots, a nut, a flange and a strip. The cage has four walls which form a four sided enclosure. Each of a pair of opposing walls contains a slot. The flange extends from the nut such that its planar surface is perpendicular to the longitudinal axis of the nut. The flange and the nut have a common opening for receiving a bolt. The strip is attached to the nut and the flange. The strip is inserted into the slots to suspend the nut within the cage. The walls and the flange are shaped to limit rotation of the flange. The nut floats in two dimensions. The nut and the flange may be removed through the bottom of the cage.
