Each stud matches the original thread pitch and knurl size so it seats in the hub without modification. The extended thread length accommodates thicker wheel spacers or aftermarket wheels that require additional engagement. Grade 10.9 rating provides the clamping force specified for the listed applications.

Fitment for Infiniti M30 and Compatible Models

Questions about this item

How often should these 10.9 grade M12x1.25 studs be inspected or replaced under normal driving?

Inspect the 10pcs set at every wheel removal or tyre rotation; replace any stud that shows thread damage, corrosion or has been over-torqued beyond the 10.9 yield point.

What is the first limiting factor when the 50mm thread-length studs see repeated hard cornering loads?

The 14.3mm knurl diameter governs hub retention; if the knurl loosens in the hub bore the stud can back out under sustained lateral force.

Do the gold-finish 10.9 studs run hotter or change noise after hours of highway driving?

Wheel studs are passive fasteners — they generate no heat or noise of their own regardless of trip length.
