The mandrel 5 has a large diameter head 6 at the end of the rivet body on the opposite side of the rivet body flange. An external thread portion 13 is provided in a region of the mandrel adjacent to the rivet body flange 2. A sleeve 14 is formed separately from the mandrel 5 and the rivet body 3, and is disposed adjacent to the rivet body flange 2. The sleeve 14 includes a sleeve flange 15 for sandwiching a second attachment member 22 between the sleeve flange and a first attachment member 21, and a deformable swage-able portion 17 to be deformed radially in a region of the external thread portion, so as to form an internal thread portion 33 in the inner surface thereof.
