Description
The 6-203 / E540 Trailer Axle Spindle Nut is a heavy-duty hex spindle nut used to secure the hub assembly onto the trailer axle spindle. It threads onto the spindle and holds the inner bearing, outer bearing, washer, and hub firmly in place while allowing for proper bearing preload.
Made from high-strength steel, the 6-203 / E540 is built to withstand the constant vibration, heavy loads, and road shock experienced by trailers in South Texas. It is a standard replacement part for many common trailer axles and should be installed with the correct torque specification and a matching lock washer for safety.
This spindle nut is commonly used on utility trailers, flatbeds, equipment haulers, and ranch trailers.
