Abstract
The bolt of the present invention can reliably peel coating even when fastened with a low torque, and can secure sufficient conductivity. A coating peeling part for peeling coating is formed at a tip end of an axis part in which a regular screw part is formed. The coating peeling part includes crushing parts having a trapezoidal top part and having a flank which is projected at a different angle with respect to the flank of the regular screw part; and a protruding part which is arranged adjacent to the crushing parts and whose top part projects beyond the outer diameter of the regular screw part.
