Stops wheel / hub vibrations and many tire wearing problems.No more loose wheels - stops wheel movement (clocking) on the face of the hub.Eliminates wasted fuel caused by rolling resistance - "drag". Meets and exceeds Standards of SAEJ1965 for torque tension.Replaces all style M22 flange nuts on hub-piloted wheels.Special graphite coating prevents the nut from rusting onto the hub.Fills in the gap between the stud and the bolt hole.Skirt Nut's flange washer takes over 2,500 lbs. of force to pop off the nut which is 50 times more than standard 22 mm flange washers!Extended threading allows the Skirt Nut to go down into a Hub-Piloted Disc Wheel an extra 3/16" (5 mm) into the stud hole.
