R&P Service Insight
Wheel studs should be matched by measurement, not just by axle rating. A stud that is too long, too short, or the wrong knurl diameter can create installation and lug-nut seating problems.
- Check the Knurl: The knurl must match the hub or drum bore for proper press-fit retention.
- Check the Length: This listing is for the 2" version, not the 2.25" 007-150-00 version.
- Check the Application: Confirm hub, drum, axle capacity, and existing stud measurements before ordering.
R&P Knowledge Hub

Vehicle / System Fit: Trailer hub and brake drum wheel stud replacement for compatible press-fit applications.
Installation Notes: Press the stud into the hub or drum squarely. Do not rely on the lug nut alone to force an improperly matched stud into place.

R&P Repair Insight
Replace wheel studs when threads are damaged, stretched, cross-threaded, or when the stud no longer seats properly in the hub or drum. If multiple studs are damaged, inspect the wheel, lug nuts, hub face, and drum condition before returning the trailer to service.
- Thread Check: Confirm 1/2"-20 lug nuts are being used with this stud.
- Seating Check: Make sure the stud head seats flat after installation.
- Torque Check: Re-torque wheel hardware to the trailer or axle manufacturer’s specification after installation.
