摘要:
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 4 for peeling coating is formed at a tip end of an axis part 2 in which a regular screw part 1 is formed. The coating peeling part 4 includes crushing parts 5 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 1; and a protruding part 6 which is arranged adjacent to the crushing parts 5 and whose top part projects beyond the outer diameter of the regular screw part 1.
