Replacement Screw and Nut for Bulldog 10K / 12K Square Trailer Jack

Updated 03/14/2025 | Published 04/22/2014

Question:

I am looking for a screw and nut for my square trailer jack. I think it is a pre-2003 Bulldog 10k or 12k jack. Do you have the part and can you send me a picture of it so I can compare it to mine? Thanks,

The screw and nut assembly, # BD500250, fits Bulldog jacks rated at 10,000 lb lift and 12,000 lb support.

We also have kit, # BD500217, which is designed to fit Bulldog series 182 jacks from 2003 to present with a 12,000 lb capacity.

I have included a picture to give you the dimensions of each product.
