1 x Trailer Caravan Castle Nut 1" UNF Black Finish For Parallel & 2 Tonne Bearings

Secure your trailer hub with confidence using this 1" UNF Trailer Castle Nut, designed to suit trailer hubs fitted with Parallel and 2 Tonne bearing combinations. Manufactured with a durable black finish and precision-machined fine thread, this castellated nut is an essential component for safely retaining your trailer hub and wheel assembly.

Featuring a 1" UNF fine thread and a traditional 6-slot castellated design, the nut is used together with a split pin to lock the bearing adjustment in place, helping prevent the nut from loosening during towing. It is commonly fitted to 50mm square trailer axles used on many Australian trailers and caravans.
