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

Mardarth 20-piece M12x1.5 closed-end acorn lug nut set with 3/4" (19mm) hex and 1.26" overall length, engineered to match OEM 60° cone-seat specifications for a secure, corrosion-resistant wheel fit.

This complete set of 20 lug nuts is built to replace factory acorn lug nuts on a range of Ford and Lincoln models, including Focus, Fusion, Escape (aluminum wheels), Ranger, Bronco, MKC, MKZ and Corsair. Each nut is a one-piece solid design finished in black and tested for corrosion resistance to keep threads protected from road grime, salt and moisture. The closed-end configuration, standard 3/4" hex, and M12x1.5 thread pitch make these nuts an easy, direct swap for stock wheels and many aftermarket wheels that use a 60° cone seat.

Will these nuts fit my vehicle and wheels?

These lug nuts are manufactured to OEM-style dimensions: M12x1.5 thread pitch, 3/4" (19mm) hex, 1.26" total length, and a 60° cone seat. They are designed as direct replacements for specific Ford and Lincoln factory wheels and many compatible aftermarket wheels using a 60° bulge/cone seat.

• Fits models: Ford Focus (2012–2018), Fusion (2012–2020), Escape (2013–2025 aluminum wheels), Ranger (2013–2025), Bronco (2021–2025)

• Direct replacement for OEM part numbers: #611303, ACPZ1012H, CV6Z1012C

How do these lug nuts resist corrosion and wear?

The Mardarth lug nuts use a one-piece solid construction instead of the typical two-piece capped design, eliminating a common rust trap. They undergo salt spray testing (72 hours) to verify corrosion resistance and use a closed-end to keep contaminants out of wheel studs and threads.

• One-piece solid construction reduces trapped moisture and rust points
• Closed-end design protects threads from dirt and salt
• Black finish adds an extra barrier against corrosion and meets aesthetic needs

Are these lug nuts easy to install and use with standard tools?

Yes — the universal 3/4" (19mm) hex size works with common sockets and impact tools used in home garages and professional shops. The nuts are designed for a straightforward swap with factory wheels, minimizing installation time for both DIYers and mechanics.

• Standard 3/4" (19mm) hex fits common sockets and impact wrenches
• Closed-end, solid design installs like OEM nuts with no special adapters
• Sold as a set of 20 to cover full-wheel replacement or emergency spares

What safety and compatibility details should I confirm before buying?

Always verify your vehicle’s thread pitch, seat type, and desired stud engagement length before purchasing lug nuts. While these nuts match many OEM specifications, wheel manufacturers sometimes specify different seat styles or extended length requirements.

• Confirm M12x1.5 thread pitch and 60° cone/bulge seat on your wheel
• Check that 1.26" overall length provides proper stud engagement for your wheel
• Consult wheel or vehicle manual if using aftermarket wheels with special seat types

Who is this for: This 20-piece Mardarth lug nut set is ideal for owners of compatible Ford and Lincoln models who want an OEM-style replacement that resists corrosion and simplifies maintenance. It’s also a good choice for mechanics and enthusiasts who need a reliable, closed-end acorn nut set in a standard 3/4" hex size for quick installation on factory or many aftermarket wheels.
