Part Number: 33038U-6 1/2"-20 Thread Set of 6 StudsOverviewThis 6-pack of drive-in wheel studs is a clean replacement option for compatible trailer hubs using a 1/2"-20 wheel stud with a 2" overall length and approximately 0.561" to 0.562" spline diameter. Commonly used in boat trailer service, these studs are intended for applications where the existing hub, stud hole, thread size, spline diameter, and stud length match.
R&P Service InsightWheel studs are small parts, but they carry real clamp-load responsibility. A worn, stripped, spinning, or damaged stud should be matched carefully before replacement.
Compatibility: Designed for hub applications using 1/2"-20 drive-in studs with approximately 0.562" spline diameter and 2" overall length.
Vehicle / System Fit: Commonly found on boat trailers and compatible UFP-style trailer hubs where dimensions match.
Installation Notes: Confirm spline diameter, base diameter, spline length, thread size, and overall length before pressing into the hub.
Performance Insight: A drive-in stud depends on correct spline engagement; an undersized or oversized spline can cause poor retention or hub damage.
Brand & Fitment NoteSelling Brand: R&P Carriages replacement wheel stud set.
Application Reference: Ranger and UFP names describe common compatibility and application style only where the listed dimensions match the customer’s hub.
What This Means: This listing is for a 6-piece replacement wheel stud set, not a guaranteed OEM-branded item unless specifically stated and verified.
Before Ordering: Verify thread size, stud length, spline diameter, spline length, base diameter, hub condition, and lug nut compatibility before installation.
