Threaded steel coupler system Coupler

Reinforcing steel screw connection for force transmission for static and dynamic loads

A screw connection consists of a threaded sleeve and a thread into which the reinforcing bars to be connected can be screwed.

The Coupler is designed as a screw connection reinforcement on formwork of working joints in concrete. It combines reinforced concrete components with maximum force transmission for static and dynamic loading.

The Coupler system offers a method of connecting steel – even with larger diameters from 12 mm – simply, quickly and economically.

A wide range of standard and special variants of the screw connection allows the MAX FRANK screw connections Coupler to be combined in any configuration.


  • Reliable protection of CA socket rods with thread protection caps
  • Optimum force transmission in the working joint
  • Use of the static advantage of an "indented joint" by consideration of the geometry
