KOBSERT® thread inserts for metals

Thread reinforcement for metals

High-strength joints

You can use KOBSERT® thread inserts to create vibration-resistant and torsion-proof nut threads in metals with low shear strength.

Plus factors

Advantages of KOBSERT®

  • High-strength threads

    Benefit from high-strength fastenings in metal materials with low shear strength, even with small screw-in depths.

  • Strong joint

    KOBSERT® thread inserts are anchored mechanically without additional securing pins or washers and without chemical adhesion or sealing materials.

  • Fully sealed

    No leaks. The KOBSERT® thread insert with sealing ring ensures gas and liquid-tight joints.

Method and principle

Easy handling

When installing KOBSERT® thread inserts, the locking flange is pressed until it is flush with the surface of the workpiece. This causes the pipe-shaped neck area below the locking flange to shorten and bend outwards towards the mounting thread. Following installation, the thread inserts are reliably protected against unscrewing, even when the part is exposed to dynamic screw load or extreme temperatures. Setting also prevents thread backlash between the insert and the thread in order to minimise setting phenomena under load.
