Hollow-bar nails

Hollow-bar nails consist of three main components: the nail head, the steel tendon – including sleeve and single-use drill bit – and the grout body. The steel tendon is a hollow steel bar with coldrolled round thread and can therefore be cut or joined at any desired point.



  • Nationally approved system with internal and external quality control
  • Well suited to transport and assembly conditions thanks to delivery in parts with couplers
  • A wide selection of drill bits allows use in a wide range of soil types
  • Easily adaptable to required length on site, e.g. with varying geological conditions by using partial sections with couplers
  • Excellent bond between SHS-bar and cement mortar thanks to threaded ribs
  • Can be closely matched to the required loads thanks to wide range of cross-sections
  • Facilitates rapid building progress since drilling, installation and injection of the nail are carried out in a single operation
