Abstract: An item such as a passenger assist handle is anchored to an automotive framing component by a mounting stud passing through a hole in the framing component. The mounting stud includes a shaft with a helix at a first end and a threaded portion at a second end. The helix and threaded portion are of opposite hands and the threaded portion receives a stop nut thereon. The automotive framing component has a teardrop shaped opening therethrough having a first diameter substantially equal to the diameter of the shaft and a second diameter substantially equal to the radius of the helix. Upon threading the nut onto the shaft, while the stud is held initially stationary by frictional engagement between its surface and surfaces of the framing component adjacent to the teardrop shaped opening, the stop nut bottoms against a shoulder on the shaft and then begins rotating the shaft to drive the helix through the teardrop shaped opening.
