Perfect combination of space-spacing and wear-resistant thread strength


  • In low-strength metal materials

  • In plastics


Optimal force distribution


Flexibility of the thread inserts compensates for pitch and angle errors



Thread insert sits securely



Minimised thread friction torque and minimised torsional stress



Increased corrosion resistance



Space and weight minimisation


Smaller number of required connection points and/or reduced screwing dimensions



Costs minimised


By reinforcing the thread, which effectively minimises the repair costs



Integrated loss protection

The clamping torques are comparable with the values of DIN 267 Part 15 or DIN EN ISO 2320.
