ー溝を形成し、頭部外周面を円筒状としている。For example, as shown in FIGS. 4A and 4B, a conventional nut with an anti-theft function is formed by forming the outer peripheral surface of a nut body 12 having a screw hole 11 at the center thereof into a cylindrical shape. A keyway 14 having a special shape is formed on the top surface 13 of the nut main body 12 so that rotation is impossible with a wrench or a spanner. The nut main body 12 is rotatable by using a special wrench 17 in which a key projection 15 that fits the key groove 14 is formed on the ceiling surface of the cylindrical hole 16. The cylindrical hole 16 has a slightly larger diameter than the cylindrical outer peripheral surface of the nut body 12, and a square or hexagonal head 18 is formed on the upper part of the dedicated wrench 17. The shape of the key groove 14 and the key protrusion 15 is different for each product, and the nut main body 12 is used unless a dedicated wrench 17 having the key protrusion 15 matching the shape of the key groove 14 is used. Cannot be rotated. Also, in the case of a conventional bolt with an anti-theft function, it is almost the same as the above-mentioned nut, that is, a key groove similar to the above is formed on the top surface of the head of the bolt, and the outer peripheral surface of the head is made cylindrical. .
