Availability of a Replacement Castle Nut for a Harbor Freight Trailer


Hi, I need a castle nut for my Harbor Freight trailer to hold on the hub. I think its a 25mm. Do you have it.


Expert Reply:

25 mm is very close to 1 inch, so there is a good chance the castle nut part # 165686 would fit as it is 1 inch. This has 14 threads per inch, so you will need to compare that to your spindle to determine if it will match up.
