Bolts and screws are selected very carefully as components for industrial
applications and integrated precisely into the design. Accurate
determination (via tensile tests) of the elastic tensile modulus and the limits
of elastic loading is essential, as from this the limit forces for a secure,
reliable screwed fastening are established. The huge number of applications requires a vast range of screws and bolts of many different types. Zwick’s comprehensive selection of specimen grips, with the option of customized solutions, simplifies testing in this area.
