Common questions
How do I confirm 12x1.25 is the right thread for my studs?
Check your vehicle's stud specification or an existing lug nut. A correctly matched nut threads on smoothly by hand; if it binds after a turn or two, the pitch is wrong. Never force a mismatched nut, since that damages the studs.
Are these interchangeable with standard conical seat lug nuts?
No. ET style uses a shank and separate conical washer designed for old style E-T wheels. Conical, mag, and ball seats each require their own matching hardware.
