Ranger Trailer Socket Size

I just purchased a 2015 Ranger 621 and the previous owner said that the trailer requires a thin walled socket. Does anyone know what size it is or a cheap set on Amazon that would work?

I thought I would check on here before I start buying all sorts of different brands.

Most trailers are usually close to a 13/16" or 3/4"......

Thanks in advance...

I'm referring to the lugnut size...

Sorry I forgot to mention that.

13/16 for my 2014 Ranger 620 👍
