4 Lug Nuts Acorn 9/16 Duplex

The GORILLA 4 Lug Nuts Acorn 9/16 Duplex set delivers precision wheel fastening engineered for vehicles requiring robust, corrosion-resistant hardware. These right-hand threaded lug nuts feature a 9/16-18 pitch and 7/8-inch hex head, providing secure engagement on standard automotive wheel studs. The closed-end acorn design with 60-degree seating offers complete protection to stud threads and a professional appearance, making this set ideal for vehicle maintenance, restoration projects, and long-term wheel security.

Each lug nut in this four-piece set is manufactured from steel with a chrome finish, delivering excellent resistance to road salt, moisture, and corrosive environments. The 60-degree tapered seat ensures proper load distribution and prevents loosening from vibration—critical for both highway and off-road driving. Chrome plating provides a protective barrier while maintaining the polished aesthetic expected on restored or custom wheels. The duplex design accommodates duplex studs, a common specification on pickup trucks, heavy-duty vehicles, and commercial applications where dual wheels or reinforced fastening is required.

This set serves owners performing wheel maintenance, restoration work, or replacement on vehicles with 9/16-18 duplex studs. The closed-end acorn design is particularly valuable in environments where stud corrosion is a concern—coastal regions, areas with heavy road salt application, or vehicles stored outdoors. Replacement or spare lug nuts from a trusted brand like GORILLA ensure wheel security across multiple seasons and varied driving conditions. The modest weight and compact packaging make this set convenient for emergency kits, tool storage, or professional automotive shops stocking OEM-compatible hardware.
