We have created all of the components needed to economically install the steel nutsert or Riv-nut for the exterior mirrors that mount to the car doors.
Our steel Riv-nut uses a 1/4 inch hole. You will need a 5/32 Allen or hex key, 3/8 inch wrench, and a 7/16 inch wrench.
The Riv-nut needs to be assembled on the kit as shown prior to installation.
The assembly is installed flush, in the pre-drilled hole. The Allen wrench and the 7/16 are held stationary, while the 3/8 wrench is used to tighten the nut clockwise. With the possibly different sheetmetal thicknesses, we are unable to give a definitive torque for tightening. Watch for the upcoming video showing the easy installation.
Kit also includes a spare nut, easily does 4 Riv-nuts.
