Factory lug nuts get the job done, but they rarely hold up well under the demands of lifted trucks, larger wheels, and off-road use. Rough Country's M12 x 1.5 spline lug nut set gives your 2019-2026 Ranger or 2021-2026 Bronco a secure, corrosion-resistant fastening solution that exceeds OEM strength and hardness standards, finished in a clean matte black to complement any wheel color or style.
Cold-forged carbon steel construction. Each lug nut in this 24-piece set starts as cold-forged carbon steel, a process that increases material density and rigidity compared to cast alternatives. The result is a lug nut that exceeds OEM specs in both strength and hardness, giving you confidence whether you're daily driving or tackling rougher terrain.
Bulge acorn seating for maximum contact. The closed-end bulge acorn design provides over 6% more seating surface area than a standard acorn lug nut. That additional contact area distributes clamping force more evenly across the wheel seat, reducing the risk of wheel movement and making this set especially well-suited for aftermarket wheels.
Spline drive design with included socket key. The spline drive pattern requires the included socket key for installation and removal, adding a layer of security against wheel theft. The key fits standard drive tools, so swapping wheels on the trail or in the driveway stays straightforward.
Long-lasting black finish. The black finish resists corrosion across seasons and driving conditions, maintaining its appearance through mud, salt, and moisture exposure without flaking or bubbling over time.
