摘要:
The object of the present invention is to provide a bolt, the axial force of which can be measured by a supersonic wave, or the like, with high accuracy and which can be manufactured in a shortened process.A bolt 1 having an angular polygonal shaped bolt head 2 is provided in the present invention. A recess 4 is formed on the bolt head 2 and a projection 5 having a plane upper face 6 is formed on the inner side of the recess 4, and at the end of the bolt shaft 3, a plane end face 8 is formed, and a wall, the outside of which being a C-face part is formed around the plane end face 8.
