Title:
BOLT
Document Type and Number:
WIPO Patent Application WO/2015/049761
Kind Code:
A1
Abstract:
With this bolt, a coating can be reliably removed even if low-torque tightening is performed, and sufficient electrical conductivity can be ensured. On the tip of a shaft part (2) on which a normal screw section (1) is formed, a coating removal section (4) for removing a coating is formed. The coating removal section (4) has a pedestal shaped apex section, and is formed by the following: a flattened section (5) in which a flank portion thereof is caused to project at a different angle than the flank portion of the normal screw section (1); and a protrusion section (6) in which the apex section is caused to project more than the outer diameter of the normal screw section (1).
