ABSTRACT:
A multifunction wheel nut cap is used on motor vehicle to indicate loosening and rotation of a lug nut. On large trucks on which the lug nuts have to be frequently torqued to prevent the lug nut from loosening and turning until it drops from the wheel bolt, the indication of rotation and limiting of the rotation prevents the lug nut loss and requires tightening only when there is an indication that the lug has become loose. The Wheel cap nut device gives a visual warning when a nut has become loose. It also prevents water and contaminants from penetrating the lug nut and bolt threads.
