Abstract
A fastening apparatus includes a compression limiting member having a dowel portion and a belleville washer portion. A first member defines a first hole, a second member defines a second hole, a third member defines a third hole, and the dowel portion defines a fourth hole. The second member is between the first and third members, and the dowel portion extends through the second hole. The dowel portion is substantially rigid to prevent excessive compression of the second member between the first and third members. The belleville washer portion is elastically compressed between the second and third members such that the washer portion biases the second member toward the first member.
