DIN 934 DUPLEX Hexagon nut

Hex Nut
A hex nut is a fastening device with threads that creates a connection using a screw, bolt, or pin.

Field of Application DIN 934 is used for securing and joining parts together with bolts, screws, and other fasteners in machinery and construction.

Material of Manufacture Duplex. Duplex, in its composition, is very similar to austenitic steel. The main difference is that it has a higher chromium content - 20-28%, an increased amount of molybdenum - up to 5%, a relatively low nickel content - up to 9%, and nitrogen content - 0.05-0.5%. This steel is widely used in various applications, including water desalination plants, bioreactors, hydraulics, shipbuilding, as a replacement for austenitic steel, in heat exchangers, marine installations, platforms, and pipelines, as well as in the automotive industry.

Uncoated.

Analogues GOST 7805 (with full threads), GOST 7798, and DIN 931 (with partial threads), ISO 4017, PN 82105.
