Overview

This listing is for a set of eight replacement trailer wheel studs for hub and wheel mounting service. Each stud measures 1/2" thread diameter, 2.25" overall length, with a .62" spline diameter and 1.5" long threaded section. These studs are intended for replacing worn, damaged, stripped, or missing trailer wheel studs when the listed measurements match the existing hub setup.

R&P Service Insight

Wheel studs should be matched by measurement, not by appearance alone. The thread diameter, spline/knurl diameter, overall length, and thread length all matter for correct hub fitment.

  • Thread Size: Verify the 1/2" thread diameter before ordering.
  • Spline Fit: Confirm the hub accepts a .62" spline/knurl diameter.
  • Length Check: Match both the 2.25" overall length and 1.5" threaded section to your application.

R&P Knowledge Hub

Compatibility: Use only where 1/2" wheel studs with .62" spline diameter and 2.25" overall length are required.

Vehicle / System Fit: Commonly used in trailer hub and wheel mounting service when the stud dimensions match the hub.

Installation Notes: Press-in wheel studs require proper seating in the hub. Do not force an incorrect spline size into the hub bore.

Performance Insight: Correct spline engagement helps maintain a secure hub-to-wheel connection and supports proper lug nut torque retention.

Brand & Fitment Note

Selling Brand: R&P Carriages

Application Reference: Replacement trailer wheel stud hardware for matching hub and wheel mounting applications.

What This Means: This listing includes eight replacement wheel studs only, supplied as a lot of eight.

Before Ordering: Compare your old wheel stud to the listed thread diameter, overall length, spline diameter, and thread length.

R&P Repair Insight

A damaged wheel stud can affect lug nut engagement and wheel security. When replacing studs, inspect the hub, lug nuts, wheel holes, and surrounding hardware before putting the trailer back into service.

  • Inspect the Hub: Make sure the stud bore is not wallowed out or damaged.
  • Check Lug Nuts: Replace lug nuts if threads are worn, rounded, or cross-threaded.
  • Torque Properly: After installation, torque wheel nuts to the trailer or wheel manufacturer specification.
