DIN 928 specifies the characteristics of square weld nuts, a type of fastener that provides a threaded hole ready for a bolt or screw in metalwork projects. These nuts are designed for use in creating strong, permanent threads in a workpiece without the need for tapping or threading operations. The standard outlines critical dimensions, material specifications, and the mechanical properties required for square weld nuts, ensuring consistency and reliability in their application across various industries. By adhering to DIN 928, manufacturers and engineers are assured that the square weld nuts they incorporate into their projects meet stringent quality criteria, including the ability to withstand the stresses of welding and the load-bearing requirements of the assembly. This standard facilitates the integration of these fasteners into metal assemblies, where they provide robust, threaded attachments for securing components together.
