Its multi-stage retention layout preserves adjustment accuracy by resisting back-off during vibration, helping wheel-end assemblies operate with consistent bearing load. The nut’s heavy-profile machining helps it mate firmly to spindles found on many trailer axles, and the tool socket design simplifies torque checks during scheduled inspections. This fastening approach gives fleet shops a dependable method for holding critical wheel components firmly in place. Shop the Stemco 447-4743.
