Flange Nut, Non-locking (ANSI ASME B18. 2.2)

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.
