Discover more about the Metric Serrated Flanged Hexagon Nuts range

Serrated Flanged Hexagon Nuts are ideal for applications under vibration. Along with providing increased load distribution, the serrated flange prevents the nut becoming loose by biting into the surface of the mating assembly.

Serrated Flange Nuts can be used as an alternative to a Hex Nut and Anti-Vibration Washer, reducing the part count of the assembly. This approach is ideal when trying to achieve a value-engineered locking solution.

Metric Non-Serrated Flange Nuts are also available from Accu, designed for applications where an integrated washer is required for load distribution, but needs to be flat to the surface material so it doesn't contain serrations.


Stainless Steel Serrated Flange Nuts in this range are manufactured in A2 and A4 Stainless Steel, with either a natural or Matte Black finish available.

Thread sizes M5 up to M12 Serrated Flange Nuts can be purchased in Zinc Plated 8.8 Hardened (High Tensile) Steel.

Metric Serrated Flange Nuts

Metric Flange Nuts with a serrated underside are available from Accu in thread sizes M3 up to M16, with Flange Diameters ranging from 8mm to 42mm.

Imperial Serrated Flange Nuts

Please see Accu’s Imperial Serrated Flange Nut range for imperial sizes.
