DIN 6923 – 1983 Hexagon Nuts With Flange

Short Description:

Equivalent norms: ISO 4161; EU 1661;

Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. They are commonly used in manufacturing assembly lines where operations are speeded by using a single fastener instead of a nut and washer.

We have acquired the reputation of being the most reliable Serrated Flange Nut Supplier of Industrial Flange Nut in this sector. The serrations on Metric Flange Nut are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations, they cannot be used with a washer or on surfaces that must not be scratched.

Heibei Hanwang design a variety of serrated flange nut types in grade 5, grade 8, and Stainless Flange Nuts with A2 and A4 standard, We also offer the best quality Heavy Duty Hex Nuts that meets national and international standards of both DIN and ISO.
