A tilting terminal clamp having a clamping plate with a central, raised, frusto-conical annulus is provided with an aperture wall having a straight line portion to engage a retaining ring of a screw. This straight wall portion is preferably coined into the annulus aperture which has an upper, inclined wall portion of a greater diameter than the diameter of the straight portion in order to receive a fillet joining the head of the screw to the screw shank. To avoid cutting strands of wire from a clamped, stranded terminal wire, the lower peripheral edge is formed without a sharp burr edge, and a burr edge is formed on the upwardly facing side of the clamping plate. Increased holding power for gripping the terminal wire is provided by extending the serrations from the frusto-conical annulus to the outer peripheral edge of the clamping plate, and by making the serrations increasingly wider and deeper as they flare outwardly from the annulus to the outer, peripheral edge of the clamping plate.
