We don't have this one tied to a specific figure or model application in our records, so we can't tell you exactly which bracket or assembly it's meant for. If you're matching up old hardware on a rebuild, this is the kind of nut worth keeping a few of in the drawer.
Give us a call if you want to confirm it's the right thread and size for what you're working on before you order.
