Common questions
How do I confirm 12x1.25 is the right thread for my vehicle?
Match it to your wheel studs, not the wheels. Check your current lug nuts, thread one onto a spare stud by hand, or use a thread gauge. A 12x1.25 nut will not thread smoothly onto a 12x1.5 or 12x1.75 stud.
Will these seat on wheels made for conical, mag, or ball seat nuts?
No. Seat styles are not interchangeable. These are ET style nuts built for old style E-T wheels, and other wheel designs need the nut style that matches their own seat.
