A clamp for seating a circuit card assembly (CCA) in a chassis, and for thereafter establishing thermal contact between the CCA and the chassis, includes a shaft and two wedges that extend substantially the length of the CCA. One wedge is affixed to the CCA and the other wedge moves laterally relative to the fixed wedge to expand the width of the two wedges and thereby urge thermal contact between the CCA and the chassis. The shaft is disposed in mating slots in the sliding faces of the two wedges and is joined to the fixed wedge to seat the CCA in the chassis by threading the shaft into the chassis, without effecting lateral expansion of the wedges. A flanged nut on the shaft may thereafter be used to effect longitudinal movement of the free-floating wedge to laterally expand the two wedges without affecting CCA seating.
