The castle nut holds the wheel hub and the tapered wheel bearing on the axle spindle. It is tightened with the correct clearance and then mechanically secured with a split pin — a simple but critical safety feature that prevents the nut from loosening due to vibrations. Fits your trailer, caravan, boat trailer, car transporter and horse trailer.
