DIN
Detailed Information

This standard covers heat-treated thread rolling screws with an ISO metric screw thread as specified in DIN 13-12 which allows them to form a thread capable of accommodating screws with an ISO metric thread. It specifies dimensions which are intended to ensure that the screw thread will not become deformed when the screws are driven in or when they are in service, and that screws will not fracture when subjected to normal loads.

To that end, requirements have been specified for the drilling and thread forming capability, surface hardness, torsional strength and tensile strength of thread rolling screws.

See ISO 3269 for acceptance inspection of fasteners.
