Technical regulations and scope of application
This normative document defines the key parameters for the production of cheese head screws with a slotted drive. The regulation covers products with metric threads in the diameter range from M1 to M10, corresponding to accuracy class A. Geometric parameters and tolerances for specialized screw versions must comply with the provisions of the DIN 962 standard.
In the engineering practice of EV Group China, when it is necessary to use non-standard characteristics — such as specific strength classes, special grades of alloy steels, or anti-corrosion coatings — it is recommended to follow relevant industry standards that define requirements for materials and mechanical properties of fasteners.
