4 The Ensat® self-tapping threaded insert ... Ensat® is a self-tapping threaded in - sert with external and internal threads, cutting slots or cutting bores. A continuous process of further development has brought about a number of major improvements to product characteristics. These inserts are protected by German and also foreign patents. The Ensat is screwed into a pre-formed or pre-drilled receiving hole and so automatically taps its own thread into the hole wall. This ensures a backlashfree fit with extreme loading capacity. Ensat®-3F 305 is a thread forming insert with 3 longitudinal grooves...
