Steel High-Torque 12-Point Flange Nuts
With more points of contact than a hex, these flange nuts allow you to get a better grip for more driver torque. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They have a black-oxide finish for mild corrosion resistance in dry environments. Height includes the flange.
