Abstract: The present invention provides a fastener mounting clip for use in securing a fastener to sheet material having a bore hole formed therein. The fastener mounting clip is preferably formed of a single sheet of thin spring steel. The mounting clip includes a rectilinear planar surface having opposing retainer arms extending beneath its outer edge at obtuse angles. The retaining arms are resiliently flexible and compress and expand during insertion wherein a top end of the retaining arm abuts against the sheet material when the fastener mounting clip is fully seated within the bore hole. The planar surface includes support tabs for supporting the planar surface in the plane of the sheet material and also includes a recessed aperture for receiving and retaining a fastener therein.
