Rough Country's M12 x 1.5 Bulge Acorn lug nut set gives 2021-2026 Bronco owners a direct-fit hardware upgrade that pairs security with a clean chrome finish. Cold-forged from carbon steel, these lug nuts exceed OEM specifications for strength and hardness, making them a reliable foundation for any aftermarket wheel swap. The set includes 24 pieces and a dedicated socket key so installation and removal stay straightforward.
More seating surface, more clamping confidence. The bulge acorn profile provides over 6% more seating surface area than a standard acorn lug nut, spreading clamping load more evenly across the wheel seat. That added contact area reduces the risk of wheel movement and fastener loosening under real-world driving conditions.
Chrome finish built to last. Each lug nut receives a corrosion-resistant chrome plating that holds up against moisture, road salt, and brake dust. The finish stays presentable through repeated wheel removals without peeling or pitting under normal use.
