ABSTRACT:
A stud fastener for attaching one body member to the irregular surface of a second body member so that the axis of the stud fastener is not obliquely cocked with respect to the plane of the second body member. The stud fastener has an annular collar with struck-out contact portions thereon which remain connected to the collar by a reduced area of contact to provide a yieldable connection with the second surface, permitting movement of the contacts toward the plane of the collar as a nut fastener brings the collar against the irregular surface of the second body member. In a preferred embodiment, three pads or contacts are formed and when all three have engaged the second surface, the nut fastener is torqued out so that the stud is solidly secured to the second surface without cocking of its axis with respect to the plane of the second surface.
