Abstract: Set out herein is a fastener assembly which, together with a fastening tool may be used to align and secure structural members to each other, the structural members having misaligned securing apertures. Particularly, this invention relates to a device consisting of two eccentric bushings nested and swaged together while still permitting their relative rotation, and a special tool used for their installation. The present invention also relates to the use of the nested eccentric bushings with multiple threaded fasteners and nuts, and spiral cam ended pins with spring retainers to achieve a quick-release attachment. In addition, this invention relates to the retention of the fastener members in the nested bushing assembly and the retention of the bushing assembly in the access panel when the panel is removed. The present invention relates to the use of the nested eccentric bushings in conjunction with standard round shank screws, bolts, platenuts, nuts, washers and other fastener hardware.
