Dubo Toothed Collar Rings

The DUBO-toothed collar ring is a unique addition to the DUBO-retaining ring, and is intended for use in combination with high quality steel nuts (8.8). It will now be possible to admit any desired bolt tension without damaging the DUBO-retaining ring on account of high bolt and nut loads, this design permits the use of any nut as a locking nut, which can be re-used. By putting the DUBO-retaining ring into this toothed-collar ring, optimum deformation of the DUBO-ring is obtained after tightening the nut. The deformation of the DUBO-ring causes the locking and tightening effect according to the DUBO principle.
