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.
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.
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.
