<p>PROBLEM TO BE SOLVED: To miniaturize a performing infection mold and provide a bolt with a hanging tool with a high production efficiency, boy molding a hanging tool provided in the bolt neck to separately make a flat connection piece integrally and bendably formed together with the neck and a lug member detachably fitted to the connection piece. SOLUTION: The hanging tool is constituted of a connection piece 3 formed flat and long from the neck to the side in a shorter length than the bottom outer diameter at the time of the performing injection molding and a wide circular lug member 4 separately formed. The thickness of the middle part of the connection piece 3 is made thin by a narrowly shaped part 30 formed breadthwise to make it vertically bendable. A pair of connection parts 31, 41 are formed in the free end side of the connection piece 3 and a specified position of the lug member 4 and the lug member 4 is detachably fitted to the connection piece 3.</p> |
