Mardarth Chrome Acorn Lug Nuts 14x2.0mm — 24pc OEM-Style Closed-End, 13/16" Hex

Mardarth 24 chrome acorn lug nuts — 14x2.0mm OEM-style replacements engineered to fit 2001–2014 F-150, 2003–2014 Expedition and Navigator stock wheels.

If you need a direct-fit set of heavy-duty lug nuts that match factory specifications, these 24 Mardarth acorn-seat lug nuts provide a chrome finish, closed end protection and a one-piece solid build for improved corrosion resistance and easy installation. Each nut follows OE dimensions so you can swap them onto stock wheels without adapters. The package includes 24 nuts sized at 14x2.0 thread pitch with a 13/16" (21mm) hex head and 2.126" (54mm) overall length.

Will these lug nuts fit my F-150 or Expedition?

Yes — they are designed to match common factory wheel requirements for many Ford models produced between 2001 and 2014. Confirm your vehicle uses 14mm x 2.0 thread pitch and a bulge/acorn seat before ordering.

• Thread pitch: 14 x 2.0 mm
• Hex size: 13/16" (21 mm)
• Overall length: 2.126" (54 mm)
• Seat type: bulge/acorn (60° cone)

How do these compare to factory or two-piece lug nuts?

Unlike two-piece or capped designs that can trap moisture and rust at the joint, these Mardarth lug nuts are one-piece forged units that eliminate that seam. The closed end keeps contaminants out and a 72-hour salt-spray test improves confidence in long-term durability.

• One-piece solid construction reduces corrosion risk
• Closed-end design protects studs from road salt and dirt
• Chrome finish restores a factory appearance
• Salt-spray tested for enhanced resistance to rust

How do I install and what tools are required?

Installation is straightforward: thread each lug nut by hand, then torque to the vehicle manufacturer’s recommended specification using a 13/16" (21 mm) socket. Always follow a star pattern and re-torque after initial miles driven.

• Tools: 13/16" (21 mm) socket or impact socket
• Torque to manufacturer spec (check vehicle manual)
• Install by hand first, tighten in star pattern
• Re-torque after the first 50–100 miles

Who is this for: These Mardarth lug nuts suit owners of Ford F-150, Expedition and Navigator models (2001–2014) who want a factory-style chrome finish, reliable closed-end protection and a rust-resistant one-piece design. They’re ideal for anyone replacing missing or corroded OEM lug nuts, restoring stock wheels, or preparing a vehicle for seasonal road conditions where salt and moisture are concerns.
