The screw thread is broadly utilized for all industrial products, and improvement of screw-thread conclusion in dependability is recently demanded increasingly from the viewpoint of the productivity like the erector of a product, or serious accident inhibition of the product. Moreover plastic-region conclusion bolting by exceeding the elastic region of a bolt in screw-thread conclusion in recent years attracts attention. The high bolting force is obtained, moreover it binds tight, the struggling in the force has the description of becoming small, and plastic-region conclusion can make high activity effectiveness of a screw thread on the strength. However the unknown point has not come to be used mostly and widely about the behavior of a bolt when external force interacts on the conclusion object by which plastic-region conclusion was carried out. Then in this research, the load of the axial load was carried out to a screw-thread conclusion object, the slack of the bolt at that time and fracture conditions were clarified, and a map was created.
