R&P Knowledge Hub
Compatibility: Fits trailer hub, brake drum, or rotor assemblies designed for press-in studs with a 0.54" knurl diameter.
Vehicle / System Fit: Common on utility, enclosed, and equipment trailers using 1/2"-20 wheel hardware.
Installation Notes: Studs must be pressed into the flange—never hammered. Knurl diameter must match the bore for proper interference fit.
Performance Insight: Splined knurl locks the stud into the hub flange, preventing rotation and maintaining clamp force under repeated torque cycles.
