PRODUCT INFORMATION
Product Details
Trailer Wheel Stud 1/2"-20 x 2.70" Press-In Splined 0.54 Knurl (WS-115)
Part Number: WS-115
Single press-in trailer wheel stud with 1/2"-20 threads, 2.70" length, and 0.54" knurl diameter for hub, drum, or rotor applications.
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.
Features
- 1/2"-20 thread size for standard trailer lug nut compatibility
- Press-in splined design for secure, permanent installation
- 2.70" overall length supports thicker wheel assemblies
- Precision 0.54" knurl diameter for proper hub interference fit
