Abstract

A clip-like, C-shaped sheet-metal nut and an assembly device therefor, the nut having a thread leg with an embossed thread portion and a clip leg having a through hole, with the forward end of the thread leg having an upwardly and forwardly inclined insertion plate. A pair of guide webs are integrally formed on the two lateral edges of the thread leg that extend upwardly at right angles to the leg with the upper edges of the webs protruding above the insertion plate and running parallel to the clip leg and with their side surfaces being in line with the lateral edges of the clip leg to provide a substantially outer rectangular perimeter to the nut.
