Selection Guidance
Thread pitch determines lug-nut compatibility, while knurl dimensions determine the press fit where a knurled stud is used. Under-head length includes more than the usable threaded section; an unthreaded nose and any spacer must be accounted for when checking engagement.
Calculate the total number of studs required for the job. A package count identifies individual studs and should not be interpreted as the number of wheels it services.
Installation Considerations
Measure the hub and compare the required stud dimensions before installation. Check clearance behind the hub and inside closed-end lug nuts. Use the installation method for the exact stud design, and confirm full seating without damaging the hub.
