Tie Down Engineering Roller Shaft 86031 - 5/8 in. X 13-1/4 in. Trailer Roller Shaft with Cap Nuts

The Tie Down Engineering 86031 is a 5/8 inch diameter roller shaft measuring 13-1/4 inches in length, designed to mount boat trailer rollers to the trailer frame. It is zinc plated for corrosion resistance in wet and marine environments, giving it a durable silver finish that holds up to repeated launch-and-retrieve cycles. The packaged kit includes the roller shaft along with 2 cap nuts, which secure each end of the shaft to keep the roller assembly in place during towing and boat loading. This shaft is sized to fit standard boat trailer roller brackets that accept a 5/8 inch shaft, making it a straightforward replacement when an existing roller shaft is bent, rusted, or worn out. Installation is simple: slide the shaft through the roller and bracket, then thread a cap nut onto each end to lock it down. Whether you are rebuilding a roller bunk system or replacing a single worn shaft, the 86031 provides a precise fit for 13-1/4 inch roller applications.
