Mardarth chrome 14x2.0mm acorn lug nuts 24pc — 13/16" hex, one-piece closed-end OEM fit

Mardarth 24PCS 14x2.0mm chrome acorn lug nuts are OEM-style, one-piece, closed-end replacements engineered to fit 2001–2014 Ford F150, 2003–2014 Expedition and 2003–2014 Navigator stock wheels.

These lug nuts match factory specifications while offering a one-piece solid design for improved corrosion resistance and simpler maintenance compared with two-piece capped originals. Manufactured to OE thread and hex sizes, they provide direct-fit installation and are sold as a set of 24 to cover full wheel changes and spares. The chrome finish gives a factory polished look and the closed-end construction protects wheel studs from debris.

Will these lug nuts fit my truck or SUV?

They are made to the same key measurements used by Ford OE hardware so they install without modification on compatible models. Confirm vehicle compatibility by matching thread pitch, hex size, and seat style before ordering.

• Thread: 14 x 2.0 mm (metric)
• Hex size: 13/16" (21 mm)
• Overall length: 2.126" (54 mm)
• Seat type: 60° cone (bulge/acorn seat)
• Direct replacements for part numbers: 4L3Z1012A, 7L1Z1012A, 611288, 9100042

How do these differ from original two-piece or capped lug nuts?

These Mardarth lug nuts are a one-piece solid construction rather than the two-piece design with removable caps. That reduces potential points of failure and the ingress paths where corrosion typically begins.

• One-piece solid build for fewer failure points
• Tested for 72 hours in salt spray to assess corrosion resistance
• Closed end seals the stud from dirt and moisture
• Chrome finish preserves factory appearance

What tools and torque specs are needed for installation?

Installation uses a 13/16" (21 mm) socket or wrench and follows your vehicle manufacturer’s torque recommendations. Using a torque wrench ensures safe, even clamping and prevents damage to studs or wheel surfaces.

• Required socket: 13/16" (21 mm)
• Use a calibrated torque wrench for final tightening
• Hand-start each nut to avoid cross-threading
• Follow vehicle-specific torque spec from owner’s manual

What warranty and after-sales support come with this set?

Each set includes a 1 year warranty against defects and is backed by Mardarth’s after-sales team. If you encounter fitment concerns or a manufacturing defect, contact customer support for troubleshooting or replacement options.

• 1 year limited warranty
• Dedicated after-sales support for fitment or quality issues
• Sold as a set of 24 pieces to cover full wheel changes
• Direct-fit replacements for listed OEM part numbers
