Material: steel. Property class 17H. Metric fine thread (MF). Uncoated (St), poor weather resistance.
Note! DIN 936 can be replaced with a DIN 439 nut; pay attention to the material strength and differences in dimensions.

Special nuts generally refer to nuts whose design, application, dimensions, or other characteristics differ from a standard hex nut.
Examples include low nuts (thin nuts), flange nuts, castle nuts, rivet nuts, square nuts, diamond nuts (diamond-shaped profile), sheet metal nuts, and welding nuts.
Materials include uncoated or zinc-plated steel (bright zinc, Zn, zinc), stainless steel (A2), and acid-resistant stainless steel (A4).
Choosing the right nut? The rule is that the nut’s hardness, material, and coating should be at least equivalent to those of the fastener used (bolt, screw).
