Common questions
How can I verify my studs are 5/8"-18?
Measure the stud diameter at 5/8" and count 18 threads per inch, or test-fit one of your current nuts against this spec. Trailer and truck axle documentation usually lists the stud size as well.
Does the seat style really matter?
Yes. Conical, mag, and ball seat designs are not interchangeable, and the wrong seat will not hold torque or center the wheel properly. Confirm your wheel takes a duplex acorn style nut like the one shown in the drawing.
