Mardarth M12x1.5 Acorn Lug Nuts 20-Pack — 3/4" (19mm) Hex, 60° Cone Seat, 1.26" Black

Mardarth's 20-piece M12x1.5 closed-end acorn lug nut set provides a direct OEM-style replacement with a 60° cone seat, 3/4" (19mm) hex, and 1.26" overall length for secure, corrosion-resistant wheel fastening.

These lug nuts are engineered to match factory specifications for a range of Ford and Lincoln models, including Focus, Fusion, Escape (aluminum wheels only), Ranger, Bronco, MKC, MKZ and Corsair. Each nut features a one-piece solid construction and closed-end design to keep out contaminants and reduce the risk of rust. The set of 20 makes it simple to replace all wheel nuts or keep spares on hand for wheels with larger bolt patterns or aftermarket setups.

Will these lug nuts fit my stock or aftermarket wheels?

Yes — the thread pitch (M12x1.5), 60° cone seat, and 3/4" hex size match many OEM wheel specifications for the listed vehicles so they install like factory parts. They are also suitable for many aftermarket wheels that accept M12x1.5 cone-seat lug nuts.

• Thread pitch: M12 x 1.5
• Seat type: 60° cone (OEM-style)
• Hex size: 3/4" (19 mm) for standard sockets
• Overall length: 1.26" to match factory lug depth

How do these lug nuts resist corrosion and wear?

The Mardarth lug nuts use a single-piece solid design that eliminates the two-piece capped areas where moisture and salt typically cause rust. They are tested with 72 hours of salt spray to demonstrate improved corrosion resistance compared with capped alternatives.

• Closed-end construction blocks dirt and moisture
• One-piece solid body minimizes crevice corrosion
• Durable black finish shields metal surfaces
• Tested for salt-spray resistance for longer life

Are these easy to install and compatible with standard tools?

Installation is straightforward: the 3/4" (19 mm) hex fits common sockets and impact tools used in shops and home garages. Because the nuts conform to OEM dimensions, you can use the same torque specifications recommended by the vehicle manufacturer.

• Standard 3/4" socket or impact wrench required
• Direct replacement for part numbers like #611303, ACPZ1012H, CV6Z1012C
• Closed end prevents thread contamination during installation
• Set of 20 covers complete installs and spare needs

What advantages do these lug nuts offer over factory-capped types?

Mardarth's one-piece acorn nuts remove the common weak point found in capped two-piece designs where corrosion and loosening start. The closed-end profile also helps maintain clean threads, reducing the chance of cross-threading and improving long-term reliability.

• Stronger single-piece construction versus two-piece caps
• Reduced maintenance from sealed thread area
• Better long-term fit; lowers risk of loosening on the road
• Universal look with a black finish to match many wheel styles

Who is this for: This 20-piece Mardarth lug nut set is aimed at drivers and technicians who need a dependable, OEM-form replacement for Ford and Lincoln vehicles listed, or for anyone fitting aftermarket wheels that accept M12x1.5 cone-seat nuts. It's a practical choice for DIYers refreshing wheel hardware, fleet maintenance, or performance-minded owners who want corrosion-resistant, easy-to-install lug nuts that maintain factory fit and torque specifications.
