A closing actuator for a sheet material clamp has a first threaded orifice in a lower clamping jaw with a threaded interior wall, a second non-threaded orifice formed in an upper clamping jaw which has a retention groove formed around the non-threaded interior wall; and an actuating screw with a retention shoulder formed between the head and the threaded shank, such that the threaded shank mates with the threaded first orifice in the lower clamping jaw and the retention shoulder snaps into the retention groove, thereby capturing the actuating screw in the upper clamping jaw when threaded into the lower clamping jaw. The second orifice may be a slotted or oval shape to allow the actuating screw to pass through the upper jaw at an angle other than perpendicularly to the upper jaw as the jaws assume various angles of relationship to each other during clamp closing and opening.
