M6 Fine Thread Grade 8.8 Hex Flange Nut (Plain)

A hex flange nut is a type of fastener that combines a hexagonal nut with an integrated, non-spinning washer (flange) at one end. This design serves to distribute the pressure of the nut over a wider surface area, which helps prevent damage to the material being fastened and makes the assembly less likely to loosen due to vibration.
