Description

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.Product BenefitsCold-Forged Carbon Steel: Enhanced rigidity and density that exceeds OEM strength and hardness ratings.Bulge Acorn Design: Over 6% more seating surface area than a standard acorn lug nut for even clamping force.Spline Drive Security: Requires the included socket key, deterring casual wheel theft.Closed-End Construction: Protects threads from debris, moisture, and corrosion.Corrosion-Resistant Finish: Black coating holds up against salt, mud, and weather exposure.24-Piece Set: Covers a full set of five-lug wheels with extras.Includes Socket Key: Ready for installation or removal without sourcing additional tools.Direct Fitment: M12 x 1.5 thread pitch matches factory specs for the Bronco and Ranger.Note: Fits 2021-2026 Bronco and 2019-2026 Ranger.
