"This paper investigates behaviour of bolts? defects (cracks) of varying magnitude that may occur in bolt production processes (compression, upsetting). The objective has been to determine whether surface micro-cracks in the bolt semi-products can be a source of macro-cracks that might occur during the further processing stages leading to a serious damage of the material utilised [1]." .
