1/2"-20 Lug Nuts

1/2"-20 Lug Nuts

Every 1/2"-20 lug nut we carry: half-inch thread diameter with 20 threads per inch, the classic SAE size. Stocked in mag, acorn, bulge acorn, ET, spline and spike styles, in chrome, black and specialty finishes.

This size is commonly found on classic Ford and Mopar vehicles, older Jeeps, many trailers and a wide range of aftermarket wheels. Always verify your thread size before ordering. Unsure which size you need? Start with our wheel fitment guide before you order.

1/2"-20 lug nut common questions

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.
