Title:
BOLT
Document Type and Number:
WIPO Patent Application WO/2017/018172
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a bolt with which it is possible to complete bolt-tightening with respect to a member to be joined, said member having a hole of a diameter that allows the shaft of the bolt to pass through but does not allow the head of the bolt to pass through, by working entirely at the near side of the hole, in other words, on only one surface, even at a site where the shaft of the bolt cannot be inserted from the far side of the hole. This bolt, in which the head of the bolt and the shaft on which a thread groove is formed are integrally formed, is characterized in that the bolt as a whole including the head and the shaft is divided into at least three parts along the axial direction of the bolt with the central axis of the bolt as the center.
