Zusammenfassung:	A nut member has first and second end faces and corners, and is formed with a plurality of protrusions, each of which is disposed at a respective corner and each of which has a lateral inner face that extends from the second end face, and a plurality of recesses, each of which is indented inwardly from a respective corner and each of which is defined by a recess-defining wall. The recess-defining wall has a lateral outer face that extends from the first end face. Each protrusion is received in and meshes with a respective recess, and the lateral outer face is in face-to-face contact with the lateral inner face when two of the nut bodies are stacked and are tensioned on a screw bolt.
