74 towards the inner thread 60 once as explained the internal thread 60 has been formed both in the end region 81 and in the remaining screw nut the subsequent offsetting of the shaped collar 74 is in this case achieved by final bending in or upset forging to a slight extent corresponding to the offset of the shaped collar 74 in principle in the embodiment illustrated in fig1 an offset can be designed to be more pronounced while in the embodiment illustrated in fig1 a securing resilient force can be achieved as a result of the increased bending of the shaped collar 74 the offset can be in the region of 1 to 2 thread pitches in the example in fig1 the offset is 1 5 thread pitches in the example in fig1 the offset is 1 thread pitch in the two embodiments it has proven to be particularly advantageous that the end region 81 which is adjacent to the accommodating slot of the shaped collar 74 is thicker than the adjacent cross section thereof which as shown in fig6 is comparatively thin and can therefore be bent back easily and simplifies the processing and production of the screw fig1 shows an embodiment of a workpiece 50 u2032 which has been developed in comparison with that in fig3 and this workpiece 50 u2032 in the same way as the workpiece 50 shown in fig3 can be used as the basis for a screw nut as shown in fig5 to fig1 in the case of the workpiece 50 u2032 only sections of the annular collar run along the circumference of the workpiece 50 u2032 in this case three sections 64 u2032 are provided which are.
