According to the abstract released by the Intellectual Property India: "This invention is a nut crimping tool [010] and [060] used to crimp a lock nut with axial slots and a groove. Crimping of a lock nut will convert it to self- Locking nut with some amount of locking torque. The tool have a taper hole made for the sizes of the lock nut dimensions. Once the lock nut is pressed inside this taper hole, the lugs will be compressed and retain a certain amount of deformation making it a self-locking nut' There are two tools described here one for the lock nut [040] with internal threads [043] and the other for a nut with external threads [093] called threaded ring [090]. For both the tools the concept is same, one with taper hole [011] and the other with a taper shaft/projection [061]. Figure-1 shows the complete crimping setup for a lock nut with internal threads."
