The DIN 6923 nut is designed with a flat or serrated flange, which increases the contact area and reduces the pressure on the workpiece surface. And the notches (teeth) create pressure when unscrewing, which prevents the nut from being unscrewed.
Such a strong and reliable connection is used in many areas of the national economy, machine tools, and mechanical engineering.
The nut with DIN 6923 flange is manufactured in accordance with GOST 50592-93 from steel with strength class 6.0, 8.0, 10.0, as well as from steel with zinc-coated and galvanized coating and stainless steel A2-70, A2-80, A4-70, A4-80.
By purchasing this fastener at www.eurobolt.com.ua, you can reduce costs, as the hardware can be used without additional washers and growers.
