How many different threads are there on a midget spindle to hold hub bearing on. Got a new set of nuts and they don’t thread on spindle. Looks like the thread is to coarse

i would get them from whoever made them.they are not all the same.cg

Yes, you need to contact who you bought them from, they usually come with the spindle, with usually adjusting cups so you can get the fine tension, or it's off to Fastenal with a spindle in one hand. Bob

Whatever the manufacture of the spindle is who you want to contact for the right spindle nut.

MPD spindles are fine thread but they used to make a fine thread and coarse thread spindle nut.

Winters, dmi and sanders I believe are all the coarse thread on them

Picked them up used. Don’t see a name on them. Indy race parts says he’s got nuts to fit
