5 On the test stand … A company’s success depends primarily on its productivity and innovative drive as well as on the quality of its services. A high standard of quality is fundamental to any company’s long-term success in the marketplace. Quality improvement and enhanced productivity are not self-contradictory. Quite the contrary: Where an efficient, functioning Quality System is in place, they serve to complement each other. For this reason, KerbKonus has invested heavily also in developing and expanding a system of internal production surveillance in its thread coating producing division....

8 TufLok®/Nytemp® for self locking internal threads Self-locking internal threads are coated with a highly elastic nylon layer, TufLok® –„der blaue Fleck“® (the blue patch). When screwing on the internal thread, this blue TufLok spot brings about a high level of surface pressure against the flanks of the mating thread. The nylon layer also fills out the axial backlash between the threads of the screw and nut, producing a vibrationproof connection which prevents the thread from working loose under dynamic stress, but can be released at any time. Self-locking TufLok internal threads have proven...
