The thread pitch on a hub pilot they’re pretty much all the same. I believe it’s 22 mm x 1.5 mm. The head of the stud, length and knurled shank is wants different. If you’re looking for replacement, studs, you have two options either knock one out take it to the parts store. They’ll bring out a Euclid book and you match up the stud you have. Second option, you can call the manufacturer. They should be able to tell you a part number. When it comes to stud pilots, hub pilots and even Dayton hubs. The studs are completely different from one another.

The knurle on the stud fit on wheel bearing. The hole is smooth bore

Are the studs standard size?
