With reduced outer diameter for improved installation. For producing a lasting, heavy-duty female thread. With an additional screw grip (SG) area. Made of stainless steel.

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

Proof of Performance

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

Instructions

A resistant thread in 4 steps:



Step 1:


Drill a core hole or drill out the damaged thread



Step 2:


Create a receiving thread


  • By cutting using screw tap


OR



  • Without cutting using thread moulding for an even more resilient receiving thread


Step 3:


Set the thread insert


  • The helical insert can be mounted both mechanically and also by hand using the corresponding screw-in tool.


Step 4:


Break the pin


  • Separate the follower pin by tapping gently on the predetermined break point with a pin breaker, and then remove. Automatic pin breakers are also available for series production.
