Disclosed herein is a rivetless floating anchor nut assembly comprising a nut member having opposed lugs and a onepiece metal basket member which has a sleeve portion and a nut member engaging and retaining portion. The sleeve portion is adapted to be permanently deformed in an aperture in a workpiece to affix the basket member to the workpiece and the nut member engaging and retaining portion has a pair of wings each having slots therethrough in which the nut lugs are captured. The wings are resiliently flexible to permit removal and replacement of the nut member an indefinite number of times. The basket member has a hardness in the range between 34 and 38 on the Rockwell C scale. Also disclosed herein is a flaring tool useful in deforming the sleeve portion to affix the basket member and hence the assembly to the workpiece. The tool comprises an upper face and a flaring portion projecting from the upper face. The flaring portion includes a cylindrical element remote from the upper face and a frusto-conical element joining the cylindrical element and the upper face.
