ABSTRACT:
A clip nut assembly for use with thin sheet material which includes a generally D-shaped resilient clip having first and second generally parallel clamping portions biased together by an arcuate biasing strip for clampingly engaging opposite faces of a sheet inserted therebetween. A threaded nut is assembled with the second clamping portion for movement therewith. The biasing strip interconnects one end of the first clamping portion with the opposite end of the second clamping portion. This configuration allows the second clamping portion to pivot about two parallel axes and into parallel alignment with the first clamping portion during insertion of the sheet between the clamping portions to automatically align the nut for receivingly engaging a threaded bolt inserted through the sheet. The biasing strip includes an elongated generally diamond shaped aperture which gives the strip a constant strain geometry. Such a geometry reduces the possibility of permanent yield in any one portion of the clip material during installation.
