ABSTRACT OF THE DISCLOSURE A locking wedge apparatus for fastening a printed circuit board within an elongated slot in a rack. The apparatus includes an elongated center wedge having sloped surfaces at its opposite ends and two end wedges abutting against the center wedge's slopes surfaces. A screw extends lengthwise through a channel in the center wedge to connect together the two end wedges. rotating the screw in a forward direction draws the two end wedges toward each other, causing them to slide on the center wedge's sloped surfaces and thereby deflect transversely to lock the printed circuit board in place. A clutch mechanism limits the maximum torque that can be applied to the screw, to provide predetermined tightening of the apparatus and thereby prevent physical or functional damage to the printed circuit board. A biasing spring biases the wedges into longitudinal alignment, to facilitate initial installation of the printed circuit board and wedge assembly into the slot.
