Hey Sterling, thanks for reaching out. The Terran Industries Trailer Hub and Drum Assembly # TX28VJ has 9/16" studs. I am not sure why our page says 1/2" but I will work on getting that edited. Sorry for any confusion.
The hub fits a standard 5.2L-7K axle with 25580 (1.750" inner diameter) inner bearing and 14125A (1.250" inner diameter) outer bearing.
What kind of trailer do you have? Are you replacing all the hubs or just grabbing one for a spare?

Thank you for the reply Jesse. I have a trailer with 6 lug square tube axles that uses that same spindle spud. I also have 8 lug aluminum wheels that I want to use instead of the rusty crappy 6 lug steelies. I will check my lug hole size but I suspect it can make it work one way ore another. What’s a 16th of an inch amongst friends! Lol
