Abstract
A blind nut tool has spaced arms, one to extend on either side of a drywell head flange. The arms are mounted on a U-shaped channel member and the lower arm holds and retains a nut and washer pair on the underside of the flange as it is torqued on a threaded stud extending through the flange. The channel receives the stud and has a pin which engages a flat on the stud for storage of the tool.
