Swapping wheels on your F-150, Super Duty, or Raptor means the factory lug nuts often stay behind. Rough Country's chrome closed-end spline lug nut set gives you 32 cold-forged replacements engineered to exceed OEM strength and hardness, with a bulge acorn seat that delivers over 6% more seating surface area than a standard acorn lug nut. A matching spline socket key is included so installation and removal stay straightforward from the start.
Cold-forged construction where it counts. Each lug nut starts as cold-forged carbon steel, a process that compresses the grain structure for enhanced rigidity and superior strength compared to cast alternatives. The result meets and exceeds OEM specifications for material hardness, giving you confidence that your wheels stay where they belong under load.
Chrome finish built to last. A chrome plating process coats every nut for long-term corrosion resistance and a clean, polished appearance that complements aftermarket wheel finishes. The closed-end design seals the stud tip from moisture and road debris, adding another layer of protection against corrosion at the thread contact point.
Bulge acorn seating geometry. The bulge acorn taper spreads clamping load across a wider surface area than a standard acorn profile, reducing the risk of wheel deformation around the lug hole and maintaining consistent torque retention over time.

- Bulge Acorn Seat: Provides over 6% more seating area than a standard acorn lug nut for improved clamping distribution.
- Cold-Forged Carbon Steel: Exceeds OEM strength and hardness standards for secure wheel retention.
- Chrome Closed-End Design: Corrosion-resistant finish with a sealed tip to protect exposed stud threads.

Note: Fits 2015-2022 F-150 and 1999-2022 F-250/F-350 Super Duty. Verify wheel seat type compatibility before installation; bulge acorn lug nuts require a conical acorn seat in the wheel.
