Abstract
Abstract The disclosed fastener in the nut strip includes a pair of parallel retainer grooves adapted to receive a pair of retaining rods or wires which secure the fasteners in the preoriented strip form. The disclosed embodiment of the fastener is a pierce nut, which includes a generally rectangular body portion having a piercing face and a pair of flanges at the opposite face, one flange extending from each end of the nut. The rod retaining grooves are generally perpendicular to the opposite sides of the nut and located between the flanges and the axis of the threaded aperture. In the disclosed embodiment, the rods are inserted in the retaining grooves and the fastener, adjacent the grooves, is deformed to retain the rods in the grooves. The disclosed nut strip and coil of this disclosure includes a plurality of aligned nuts each having a pair of grooves on either side of the nut bore and the frangible rods or elements are retained in the nut grooves and bridge adjacent nuts. the end faces of the nuts, adjacent the grooves, are knurled in the disclosed embodiment, which spaces the nuts on the rods, in close relation, securely retains the rods and deforming the cylindrical rods into an oval shape. The knurling provides a plurality of portions projecting over and engaging the rods.
