Hex Flange Nut - Steel, M6/m8/m10/m12/m14/m16/m20 Sizes | Serrated Flange For Enhanced Locking, Vibration Resistance, Din 6923 Compliant

We are exporting of Hex Flange Nut to our clients. Serrated flange nuts are hex flange nuts with a serrated bearing surface. The nut turns freely until the serrations contact and displace material on the mating surface as the nut is tightened; less torque is needed to install than remove because the gripping action of the serrations create a ratchet-type locking feature that is resistant to vibration.
If the mating surface is painted or plated, corrosion can occur if the nut's wiping action removes the surface treatment.
The protruding circular flange increases the bearing surface of the nut allowing it to be used with irregular and over sized holes.
Used in commercial and industrial applications, serrated flange nuts are also called: serrated face lock nuts, serrated tooth nuts, spin lock nuts, whiz lock nuts.
Because the serrations must contact the mating surface to "lock", serrated flange nuts are not used with flat or lock washers.
