Common questions
What does 1/2"-20 mean? The stud is 1/2 inch in diameter with 20 threads per inch. You may also see it written as 1/2-20 or 1/2x20.
Are these right for my trailer? Many trailer axles use 1/2"-20 studs, but not all. Confirm your axle's spec before ordering.
Mag or acorn seat? Use the seat your wheel was drilled for: mag seats use a flat washer and shank, acorn seats taper. Every listing states its seat type.
You may also need 7/16"-20 lug nuts, 9/16"-18 lug nuts left hand thread lug nuts and all wheel lug nuts. See our torque reference chart for recommended tightening specs.
