The document highlights the Crown-Nut, a solution for creating threaded seats in round and square tubes, addressing anchoring issues in machining processes. It is available in various sizes and suitable for tubes with different internal diameters.
Advantages of the Crown-Nut
  • Accommodates tubes with large internal diameter tolerances due to crown elasticity.
  • Maintains the aesthetic of the receiving material without damage.
  • Offers an easy and cost-effective press-in fit, eliminating welding and crimping.
Caution
  • Avoid heat and galvanic processes post-insertion to maintain specifications.
  • Not suitable for stainless steel pipes or structural loads.
