Extended Wheel Studs M12x1.25 50mm

These 50mm extended wheel studs feature M12x1.25 threads and a 14.3mm knurl diameter. The set includes ten gold-finished grade 10.9 pin bolts designed for front and rear axle applications. They suit a wide range of Nissan and Infiniti models from 1987 to 2016 plus select Subaru vehicles up to 2016.

Installation notes and common issues

Installation requires pressing the knurled section into the hub flange until fully seated; a press or careful hammering with a drift is typical. The 14.3mm knurl must match the hub bore exactly or the stud will spin under torque. Over-length studs can contact brake components or wheel pockets if the rotor hat or wheel centre bore is shallow.

Compatibility checks before ordering

Verify your vehicle appears in the listed application range covering specific Nissan, Infiniti and Subaru models and years. Confirm the hub accepts a 14.3mm knurl diameter and that the M12x1.25 thread pitch matches the original hardware. Ensure the 50mm thread length provides sufficient engagement with your lug nuts without bottoming out or protruding excessively.

Questions about this item

How do I verify the 10.9 grade M12x1.25 studs are seated correctly after installation?

Torque each stud to the vehicle manufacturer's specification for M12x1.25 hardware, then confirm the 14.3 mm knurl is fully drawn into the hub with no visible gap and the 50 mm thread length engages the lug nut fully.

The box lists 10 pieces; do I need to purchase lug nuts or any other hardware separately?

The pack contains only the 10 extended wheel studs; matching M12x1.25 lug nuts are not included and must be bought separately if your current nuts do not suit the 50 mm thread length.

My car is a 2005 Nissan 350Z Roadster — are these the correct 50 mm M12x1.25 studs or do I need a different length?

The 50 mm M12x1.25 studs with 14.3 mm knurl are specified for the 2004-2009 350Z Roadster Z33, so this kit matches your vehicle.
