Standard DIN 7516
Thread cutting screws - Cross recessed head screws
This standard specifies dimensions, requirements and test methods for heat-treated hexagon head and slotted head thread cutting screws with an ISO metric thread as specified in DIN 13-12, with cutting flutes extending from the point of the screw to its head and designed to cut their mating thread during assembly. See the various din norms for head styles, Iso 8992 for general requirements, Iso 3269 for acceptance. This standard is intended to ensure that thread cutting screws are capable of performing the above functions without their own thread fracturing or becoming deformed. To that end requirements have been specified for thread cutting capacity, surface hardness, tensile strength and torsional strength.
