4 The Ensat® self-tapping threaded insert ... Ensat is a self-tapping threaded insert with external and internal thread, 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. Ensat®-S 302 (with cutting slot) is recommended for most application cases. In certain materials, this Ensat demonstrates a minimal inward springing action, so creating a certain screw locking effect. If this effect is not required, we recommend using...

Connections using Ensat threaded inserts permit substantially smaller overall dimensions and thus pave the way for material-saving and weightsaving designs. The illustration below shows two screw connections with equal pull-out strength. … technologies for a reliable hold 5 The Ensat®– pull-out resistance due to flange cover ...
