Title: Fastener with single-layered head

Abstract: This invention relates to sheet metal reversed L-shaped segments, two of which may be assembled to form a T-shaped structure or fastener having a single layered head. The single-layered head has a hole engageable to an expanding member, such as a screw for example. The engageable hole is formed by two half holes, each half hole belonging to each L-shaped segment. Further, the fastener has legs, which expand upon insertion of the screw into the engageable hole. The T-shaped structure is adaptable to be securely locked in a slot of a metal sheet. This strong locking is realized by two sets of levers acting in opposite directions, and having as common fulcrum the region at the edges of the slot. One set of levers is formed by the action of the screw on the two half holes which form the engageable hole, while the other set of levers is formed by the action of the screw on the legs of the two L-shaped segments.
