The DIN 2510 NF nut for flange connections complies with DSTU 10495-80.
This type of nut is considered special in use, as it was manufactured specifically to resist high temperatures, and the structure of the DIN 2510 nut is designed to allow screwing onto a pin with a thin rod.
It is used in industries with harsh conditions where the material is able to withstand extremely hot temperature conditions, such as for engines of ships, rockets, and automobiles.
DIN 2510 NF nuts are made of heat-resistant materials and have non-standard steel markings: 42CrMo4, 24CrMo5, Sk35.
