A metric hex nut with 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.
We've listed this M12 X 1.25 FINE THREAD METRIC FLANGE NUT here, although it is not to JIS specifications. We show it here as well on our page for standard metric flange nuts. It is listed here simply because it has the common pitch of 1.25 that pertains to other JIS fasteners. The head dimensions are that of a standard 12mm metric flange nut, which is 18MM AF.
