Abstract: Concrete screws are a new fastening system easy to install. Concrete screws are screwed into predrilled cylindrical holes. During installation, concrete screws cut a thread into the wall of the drilled hole. Therefore, tensile loads are transferred into the base material by mechanical interlock. The load transfer mechanism is similar to that of deformed reinforcing bars cast into concrete.

In the present paper the results of installation and tension tests in non-cracked and cracked concrete are presented. Furthermore, the test results are compared with the prediction of the CC-method for the concrete cone failure load. It is shown that the CCmethod cannot be used for the design of fastenings with concrete screws without some modification.
