Abstract

The present disclosure relates to a channel nut, a multi-piece fastener, and a method of manufacturing the same. The channel nut includes a first end, a second end, and an annular wall portion extending from the first end to the second end and defining a longitudinal axis of the nut. The annular wall portion includes an inner surface defining a cavity about the longitudinal axis, a first region, and a second region. The first region includes a serpentine profile defining a plurality of sides, a plurality of edge surfaces, and a plurality of recesses. The recesses are located at a first location of the first region, and each recess is located intermediate two of the edge surfaces. The second region includes a plurality of projections radially spaced about the longitudinal axis. Each protrusion extends from one of the first locations of the first region and toward the second end. The projections define a plurality of slots therebetween.
