If the nut is screwed off the bolt, the two parts can be separated, so the bolt connection belongs to the detachable connection. Bolts are preferred fasteners for a variety of applications because of their ease of disassembly. However, this also makes them prone to the problem of losing their pretension by spontaneous loosening. Loosening of the root bolt can have serious consequences. Loosening of a bolt may cause the whole production facility to fall into a stagnant state, even in some applications, the loosened bolt may cause serious safety hazards. Vibration, excessive pressure, temperature differences, material deformation and the like may cause loosening of the bolts to different degrees. In general, a bolt is welded and fixed by means of a welding spot or the like to prevent loosening of the bolt, but this method is difficult to disassemble the bolt, and thus, has various inconveniences, and the applicant has proposed a lockbolt member for solving the above-mentioned problems.
