The Fabco 688-0592 (also listed as 6880592) is a genuine OEM wheel hub nut featuring a 1 5/16-12 thread specification with a left-hand thread orientation. Left-hand thread nuts are a critical detail on certain axle positions where a standard right-hand nut would back off under normal wheel rotation rather than tighten. Getting the thread direction right matters for wheel-end safety and retention. This is a genuine Fabco OEM part, sold by Pro Gear and Transmission.
