DIN 937 low nut, slotted flare nut. It is used together with a cotter pin (DIN 94). The following materials are used to manufacture this unique type of fastener:
– steel 17N, 22N (galvanized);
– stainless steel A2-70; A2-80; A4-70; A4-80;
This type of fastening significantly reduces the weight of large mechanisms, structures and machine tools, which makes it possible to use metal products not only in light but also in heavy industry.
The DIN 937 low flare nut complies with DSTU 5919-73, 5933-73, 5935-73, including international certification ISO 7038.
