I wanted a slip-on bracket for the front grille of my toyota that slips on from the back, with a 6mm bolt hole centered between the grill slats. They can be snapped into place on the grille without drilling or adhesives. The back piece extends flush with the grille slats. The back face has a hex shaped recess to hold a 6mm nut.
