Steadicam 1/4"-20 Camera-Mounting Screw for Select Rigs

probably not. I don't know if there are multiple models from neewer, but the picture I saw has a standard tripod plate style screw (has part of the post with no thread to account for the thickness of the plate). This screw is specifically designed for actual steadicam brand steadicams, which have a very thin plate and thus don't need the extra post... I'd try getting some normal replacement 1/4 tripod screws first.
