Extended Wheel Studs for Infiniti Q50

These gold-finished m12x1.25 studs measure 50 mm in thread length and carry a 10.9 grade rating. They are sold as a set of ten pieces designed for the Infiniti Q50 V6 3.5 from 2014 to 2015.

Knurl diameter and bolt type guide installation

Each stud features a 14.3 mm knurl head that matches the specified hub bore for a press-fit seat. The pin-bolt design means they install with standard lug nuts and no special adapters.

Replaces factory studs when spacing changes

The 50 mm length suits applications that add wheel spacers or thicker rotors on the listed Nissan, Infiniti and Subaru models. Stock-length studs remain appropriate when no extra clearance is needed.

Questions about this item

What thread standard do these m12x1.25 studs follow, and what clamping force does the 10.9 grade provide?

They use the metric M12 x 1.25 thread pitch. The 10.9 grade rating indicates a high-strength alloy steel suitable for wheel-hub clamping loads on the listed Nissan and Infiniti models.

What hub bore and knurl diameter must the wheel hub have for these 14.3 mm knurl studs to seat correctly?

The knurl measures 14.3 mm (0.565 inch). Your hub's stud holes must match this diameter so the serrated collar bites securely without looseness.

How are these 50 mm extended studs installed, and what common mistake should be avoided when torquing the lug nuts?

Press each stud through the hub flange until the knurl seats fully, then tighten lug nuts in a star pattern to the vehicle's specified torque. Do not use an impact gun for final torque — it can stretch the 10.9 studs unevenly.
