It seems the Cordial using Metric type screws. Unfortunately the uTrack24 compatible with UNC 4-40 type of screws.
Usually the European manufacturers are including two different type of screws with the DB25 connectors, probably it may worth to ask the Cordial to get a spare screw for the connector.
The Newark also has a very wide range of accessories for DB25 connectors
Sorry for the inconveniences
