Abstract
A rivetless nut plate has a nut, a holding bracket, a member and a nut retainer. The nut is provided with an aperture therethrough and is secured within a bracket portion of the holding bracket by the retainer but also is permitted limited movement within the bracket portion. The holding bracket further includes a tubular portion having inner and outer walls. The inner wall is tapered such that the member is positioned against the inner wall. Upon an axial force being applied to the member through the aperture of the nut, the member is pushed through the tubular portion from the first end to the second end in order to expand the inner wall and force the outer wall into engagement with the wall of the workpiece. A tool is provided to push the member through the tubular member and can be incorporated into either a manual or automatic process.
