Detailed Description
Dorman 610-525 is a wheel lug stud engineered for wheel-end service on applications that use an M20-1.50 metric stud with a serrated, non-clip-head design. The steel construction supports the clamping force needed to keep the wheel seated properly against the hub, while the serrations help the stud lock into place during installation. For technicians and owners servicing wheel hardware on vehicles such as Chevrolet Silverado and GMC Sierra applications, this lug stud provides the dimensional specifications needed for a proper replacement. This part cross-references OE number 12546289 for the same application.
Common Problems This Part Can Address
- Stripped or damaged wheel stud threads
- Broken studs from over-torque or corrosion
- Wheel wobble caused by compromised lug hardware
- Difficulty achieving proper lug nut clamping force
- Service issues after hub or brake work that disturbed the original stud
Installation Notes and Tips
Verify thread size, pitch, length, and serration diameter before installation. Press the stud fully into the hub so the serrations seat correctly, and confirm the lug nut engages the full thread length without binding. Use the correct torque specification for the vehicle and recheck wheel fastener torque after service. For Chevrolet Silverado and GMC Sierra wheel service, confirm the hub and wheel hardware match the M20-1.50 metric specification before installation.
Quality Assurance
Dorman manufactures this wheel lug stud from carbon steel and tests it to demanding automotive industry standards to support strength, longevity, and safety. Part number 610-525 is built for consistent wheel hardware replacement in service applications that require a metric serrated stud.
