The principle When installing the threaded inserts, the safety flange is pressed into the surface of the parent material. (This reduces the pipe-shaped neck area under the safety flange and covers as far as the mounting thread). After installation into the part, the threaded inserts are reliably protected against unscrewing, even when the part is exposed to dynamic screwload or extreme temperatures. Due to the installation process where the KOBSERT® body is pulled into the same direction like the screwload, the clearance of the external thread is compensated. The external thread is pre-setted...

KOBSERT® Installation guidelines Mounting thread Metric ISO threads according to DIN 13, tolerance 6 H. The mounting thread should checked with a thread gauge tolerance 6 H. Thread hole The minor diameter of the thread hole has to be drilled according to DIN 13 tolerance 6 H. In general, the tapped hole should not be countersunk. Chamfering is permissible, within the diameter, but should not be greater than the specified diameter of the mounting thread. If the KOBSERT® or the KOBSERT® HP is used with a sealing ring, a cylindrical partion in accordance with pages 3 to 7 should be created. Installation...

Wall thickness specifications for aluminium materials (casted and forging alloys) The minimum width S or the wall thickness SR depends on the tenside strength and the E-Modul of the parent material. The following formula only gives guide values for aluminium alloys. For other materials, e. g. copper or brittle materials, the required wall thickness should be established by performing tests. Dimensions of the mounting thread see page 5 to 9. S = Minimum width of workpice SR = Minimum wall thickness DR = Outer diameter of safety flange (knurl diameter) Pull out load in relation to screw class on...
