An improved method and nut for preloading ball screw assemblies in which the preloading is accomplished by axially offsetting segments of the internal helical grooves of the nut member, the method comprising permanently deforming an intermediate portion of the nut member so as to cause an axial shift of the connected nut member portion and thus result in axially offset helical groove segments in these portions. The nut member is configured to accommodate readily large permanent deformations. This deformation is produced in the specific process described by rolling a peripheral groove into the nut member.
