Thread reinforcement in metals

KOBSERT® threaded bushes are the ideal solution for creating vibration-resistant and torsion-proof nut threads in metal low-strength materials, such as aluminium, aluminium alloys and magnesium alloys.

General

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 proberly.

The benefits

Technology

The KOBSERT® technology is ideal for both reinforcing threads and repairing defective threads. The threaded bush is mechanically anchored without additional securing pins or washers and without chemical adhesion or sealing materials.

The sealing ring version is designed for gas and liquid-tight joints.
