ISO 4161 Non-Serrated Hex Flange Nut by Material, Finish and Size
Non-Locking Flange Nuts are hex nut with an enlarged circular base (or flange) flaring out from the bottom of the nut, which acts as an integrated, non-spinning washer. Since the tightening torque is distributed over a larger area, there is less chance of deformation.
