Attention: The DIN 971-2 standard is considered obsolete and has been completely replaced by DIN EN ISO 8674:2013-04.
Technical aspects and scope of DIN 971-2 nuts
The DIN 971-2 standard regulates design requirements, manufacturing precision, and tolerances for type 2 hexagon nuts equipped with metric fine threads. Products complying with these standards are widely used in heavy mechanical engineering, machine tool building, and high-load instrument engineering assemblies where increased reliability of the threaded connection is required.
EV Group China supplies fasteners manufactured from a wide range of materials: from carbon steels with various strength classes to corrosion-resistant stainless alloys and brass. The use of type 2 nuts with fine thread pitch provides higher resistance to self-loosening under vibration loads compared to coarse-threaded counterparts.
