ABSTRACT:
This apparatus is a fastener assembly for retaining a spring, such as used in the brake actuators of heavy-duty trucks, in a compressed state, including a fully-compressed state, the assembly being variably adjustable to accommodate variations in actual spring dimensions and tolerances. The compressed spring is held between first and second members by a fastener assembly comprising a washer and a clip, the washer having an opening therein for receiving the clip. The clip has an enlarged head with sloping shoulders which ride on the periphery of the opening in the washer, and a shank which engages the second member and maintains the clip stationary with respect thereto. The shape of the periphery of the opening in the washer and the slope of the shoulders on the head of the clip are designed such that when the washer or clip is rotated with respect to the other from a rest position the spacing between the first and second members is progressively reduced, whereby the fastener assembly is selectively adjusted to accommodate the compressed spring in its minimum selected dimension.
