These flange nuts are designed to thread onto our stone countertop rectangular insert threaded studs for attaching sinks to stone countertops, or to the screws used in attaching sinks to solid surface countertops.
The flange nut has an enlarged circular base flaring out from the bottom of the nut. The bearing surface of the flange has serrations which displace material on the mating surface when the nut is wrenched into place, forming a connection which resists loosening.
