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.

Claims

1. A C-shaped sheet-metal nut comprising a thread leg having an embossed thread portion therein for receipt of a threaded member and a clip leg integrally connected at one end to one end of the thread leg to form the C-shaped nut, said clip leg having two lateral side edges and a through hole in line with the thread portion in the thread leg, said thread leg having two lateral side edges and a free end, an insertion plate that inclines forwardly and upwardly from said free end of the thread leg and having an upper edge and a pair of guide webs on the two lateral side edges of the thread leg that extend upwardly at right angles to the leg, said guide webs having upper edges that extend above the upper edge of the insertion plate and are parallel with the clip leg, forward edges that converge toward each other in the area near the insertion plate and outer side surfaces in line with the lateral side edges of the clip leg.

2. The sheet-metal nut of claim 1, wherein the free end of the thread leg inclines downwardly toward the clip leg.

3. The sheet-metal nut of claim 1, wherein the clip leg has a free end with rounded corners and the forward edges of the guide webs are rounded off.
