Thread reinforcement in metals

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


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.
