The safety requirements for screws are high. The test system must provide the right prerequisites for a correct test sequence:
The video shows how the universal testing machine inspekt 250 kN can be used for tensile testing of screws. The video shows a possibility for fast and safe clamping and testing of screws according to the standard specifications of DIN EN ISO. Depending on the standard, other clamping variants are also available, e.g. for diagonal tensile testing. For better alignment of the screws in a straight tensile axis during the tensile test, ball nuts are offered in different radius gradations.
