The efficient and low-cost production of large-scale product series isone of the strengths on which we havebased our our high-volume production outputin no way compromises are able to quickly and efficientlyproduce even small batches of non-standard state of the art stock control systempermits the reliable, prompt delivery ofstandard products, keeping your production running to schedule at all time sand helping to minimize your ware-housing are particularly proud of a cost-to-performance ratio which ensures satisfiedcustomers the world over. This has madeKerbKonus a reputable and respectedpartner to industry in the global issues at KerbKonus. Qualityconsciousness is a continuous threadrunning through every aspect of thecompany's work and all its products andservices. Quality is lived and breathed manufacturer in the metal processingindustry we are aware of our responsi-bility for an environmentally compatibleproduction.

Threaded inserts from KerbKonus aremanufactured in large piece human lives and safety can oftendepend upon just these tiny compo-nents, for instance in the case of airbagretaining we bear this heavy responsibi-lity, our products are tested and moni-tored in line with the most stringentdirectives. In the case of particularlycritical applications, each and everypart is exhaustively tested on state-of-the-art test equipment before it is deli-vered to you. For Example: dimensional check foreign particlesTest methodsThe loading capacity of a thread dependsin the main on the surface shell of thecomponent which is exposed to shearingstress.

7 Ensat is a self-tapping Threaded insert with external and internal thread, cutting slots or cutting continuous process of further development has brought about a number of major improvements to product -S 302(with cutting slot) is recommended formost application cases. In certainmaterials, this Ensat demonstrates aminimal inward springing action, socreating a certain screw locking effect.(see page 7 to page 10)If this effect is not required, we recommend using Ensat -SB 307 -SB 307/308(with cutting bores) was developed for materials with difficult cutting properties. This insert has a thick walland the cutting force is distributed overthree cutting short version Ensat 307 is particularly suitable where minimal material thicknesses are involved(see page 11 to page 15).Thin-walled Ensat -SBD 347/348for applications involving special space conditions (residual wall thicknesses), and also suitable for driving using a thread tapping machine (same internaland external thread pitch, see page 19).

8 Ensat -SBS 337/338with three chip reservoirs. Used primarily wherever only a small amount of chips may be permitted tooccur during the tapping process(see page 16 to page 18).Ensat -SBT 357/358with closed floor for additional sealingfrom below. (see page 21).Fields of applicationThe Ensat is used throughout thewhole of the metal and plastics proces-sing industry. Automotive Plant and equipment construction Railway supply industry Electro-technics and laboratorytechniques Household appliance Medical engineering OffshoreThread reparationEnsat is ideally suited for the fast repair of torn and damaged same screw size can be used features The Ensat has a large effective shearing surface, so ensuring a higherdegree of pull-out strength, an Ensat M4 is often sufficientinstead of a cut M5 thread(see page 5, Fig. 2). The Ensat is driven subsequentlyinto the finished workpiece. Thismeans a higher casting machine output, no rejects due to incorrectly cast-in insert components, no moulding sand trapped in the thread.

9 A pre-cast or pre-drilled retaininghole with normal tolerance requirements is sufficient for drivingin the Ensat . The thread is always precisely positioned. The Ensat is insensitive to smallareas of shrinkage. The Ensat -systemprevents damage caused by torn coverIn a workpiece made of a light alloy,the Ensat 302 achieves almost maxi-mum pull-out strength with only 30%flange cover (Fig. 3).Pull-out strengthThe Ensat is capable of withstandinghigh loads. When used in light alloys,for example, a degree of pull-outstrength is achieved which far exceedsthe yield strength of the mating (Fig. 4). technologies for a reliable using Threaded insertEnsat permit substantially smaller dimensions and consequently materialand weight-saving illustration below (Fig. 2) shows ascrew connection with different screwcross-sections.
