Swapping to aftermarket wheels on your 2021-2026 Bronco or 2019-2026 Ranger means the factory lug nuts may not seat correctly against new wheel hub faces. Rough Country's M12 x 1.5 Bulge Acorn Spline Lug Nut Set gives you a full 24-piece solution in a chrome closed-end design, purpose-built to secure aftermarket wheels with confidence and a clean, finished look.
More seating surface than a standard acorn. The bulge acorn profile delivers over 6% more seating surface area compared to a conventional acorn lug nut, distributing clamping load more evenly across the wheel seat and reducing the risk of wheel movement under load.
Cold-forged carbon steel construction. Each lug nut starts as cold-forged carbon steel, a process that increases grain density and produces greater rigidity than cast alternatives. The resulting hardware exceeds OEM standards for material strength and hardness, so these nuts hold up under the stress of off-road use and repeated torque cycles.
Chrome finish built to last. A chrome plating process gives each lug nut long-term corrosion resistance alongside a polished appearance that complements billet wheels, chrome trim, or any build where detail matters. The closed-end design seals the stud tip from exposure to moisture and road debris.
Socket key included. Every set ships with a spline socket key sized for these lug nuts, so installation and removal stay straightforward at the shop or on the trail.
