Steel Wheel Lug Nut | Style: Acorn Open End | Thread: 1/2"-20 | Length: 5/8" | Hex: 13/16" | Finish: Zinc Plated

Replace a compatible wheel lug nut with this zinc plated open-end lug nut. It features a 1/2"-20 thread, 5/8" length, and 13/16" hex.

The open-end design leaves the stud tip exposed rather than enclosing it under a cap — a common factory-style fitment on many passenger cars and light trucks. Before installing this 1/2"-20 nut, confirm the vehicle application, seat geometry, length, hex size, wheel clearance, and manufacturer-specified torque.

Frequently Asked Questions

Q: What's the difference between an open-end and a dometop lug nut?
A: An open-end nut leaves the stud tip visible, while a dometop nut fully encloses it under a rounded cap. Fitment is set by the wheel design — confirm which style your wheel requires.

Q: What thread size is this lug nut?
A: 1/2"-20. Confirm seat style and dimensions match your original hardware before installing.
