Abstract
A clinch-type fastener permits sheets to be joined at a right angle corner. The fastener includes a rectangular base with clinch-type undercut grooves along the sides. The base is connected to a partial cylindrical channel defining an axial bore for receiving a screw or pin. The axis of the channel is parallel to the undercuts and to a first sheet into which the base is clinched being received by a corresponding aperture in the base sheet. Tapered guides located on each side of the fastener directly above the undercuts facilitate placement of the insert into the sheet prior to clinching. The fastener is preferably formed by extruding metal to form a long length of material having this lateral profile. Individual fasteners can then be produced simply by cutting an elongate extrusion into small segments.
