Aftermarket wheels deserve hardware that matches their quality. Rough Country's chrome closed-end bulge acorn lug nuts replace the factory hardware on 1997-2014 F-150 and 1999-2002 F-250/F-350 Super Duty trucks with cold-forged carbon steel fasteners built to exceed OEM strength and hardness standards. The 32-piece set covers all four corners with matching hardware and includes a socket key for straightforward installation and removal.
More seating surface than a standard acorn. The bulge acorn profile provides over 6% more seating area than a conventional acorn lug nut, distributing clamping load more evenly across the wheel seat and reducing the chance of wheel movement or damage to the mounting surface.
Cold-forged construction with a lasting finish. Cold forging aligns the grain structure of the carbon steel, producing a denser, stronger fastener compared to cast or machined alternatives. A chrome plating over the finished nut resists corrosion and holds its appearance over years of use, complementing polished or chrome aftermarket wheels.
Closed-end design for a clean look. The closed tip caps off the exposed end of the wheel stud, blocking road debris, moisture, and salt from contacting the stud threads, adding protection beyond what an open-ended lug nut provides.
