Ensat® - 3F thread forming
1 / 7Pages

The Ensat® – self-tapping threaded insert … Ensat® is a self-tapping threaded insert 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 around its periphery Fields of application The Ensat® is used throughout the whole of the metal and plastics processing industry. – Automotive – Household appliance and office machinery production – Electrical and laboratory supplies – Plant and equipment construction – Sports and lifestyle equipment – Railed vehicles industry Product features ț Universal application for all types of plastic, thermoset plastics, thermoset plastics, PU/PUR foam, Fibre-reinforced plastic (FRP), for hardwood and plywood, hard paper and metal. ț Maximum strength values in comparison to other systems. The diagram illustrates the withdrawing force in thermoplastic materials: In thermoset plastics and FRP, the values tend to be higher. ț Thin-walled Ensat® for restricted space conditions (residual wall thicknesses), and also suitable for screwing in using a thread tapping machine (same inside and outside pitch). Slot version: WN 303, Three-hole version: WN 347/348 page 16 and 17. 3 chip reservoirs around the periphery Approx. pull-out force [kN] ➞ Ensat® Typ 302 female thread ➞ Ensat®-SBS 337/338 These cutting bores are shaped to serve as chip reservoirs. The chips created during the driving process stored here and cannot drop into sensitive equipment parts. For additional sealing from below: Ensat® with closed floor Works standard 357/358.

... technologies for a reliable hold The Ensat® should be processed appr. 0,1 – 0,2 mm recessed (fig. 4). After processing, the Ensat® can be immediately subjected to load. If the component material permits subsidence of the Ensat® under load, the Ensat® can only execute an axial movement of 0,1 to 0,2 mm. In other words, the pretension of the screw union is largely retained, loosening of the screw connection under dynamic load is impeded. Retaining hole The receiving hole (L, fig. 5) can be simply drilled or already provided for in the casting. Countersinking (N) the borehole (fig. 5) is...

Ensat®– driving tools... On this page, you can configure the optimum tool for your application. A configuration is provided in the following as an illustrative example. The article number is composed of two sequences of numbers and starts with the tool shank (fig. 8) which should be selected in accordance with your output. Also encrypted in this number are the special versions for thin-walled Ensat® (620 1 and 621 1) and for very high driving torques (622 0 and 623 0) which are available as standard only as a square shank. Other non-standard geometries can be evaluated as standard besides...

You can of course also use power tools for the manual assembly. If doing so, it needs to be ensured that the rotatable sleeve (2, see fig. 6) is in the corresponding correct position (see fig. 15 procedure description).

Machine driving process 1. Precisely position the workpiece so that the bore and machine spindle are at right angles to each other (do not tilt). Set the machine to the precise installation depth (appr. 0.1 to 0.2 mm below the surface of the workpiece see page 5). 2. Actuate the operating lever of the machine. The rotatable outer shell of the tool must be resting against the outer visible stop pins at the beginning of the turning process so that it is driven by the pins in the clockwise direction. 3. Feed the Ensat® towards the tool (slot or cutting hole facing downwards) and grip for the...
