Mardarth 14x1.5 Chrome Lug Nuts 20Pc — 1.5" Closed-End Acorn, One-Piece Durable Finish

These are a set of 20 Mardarth 14x1.5 acorn-seat, closed-end chrome lug nuts, 1.5" long, made as a direct replacement for specified stock wheels on Camaro, Corvette, Equinox, Impala and similar models.

Designed to replace worn or damaged lug nuts on compatible GM vehicles, this 20-piece kit provides a one-piece solid construction with a chrome finish for corrosion resistance and a clean, factory-style appearance. The nuts use a 14x1.5 thread pitch, a 60° conical seat, and require a 7/8" (22 mm) socket for installation. They are closed-end acorn nuts, 1.5" (38 mm) overall length, intended for stock wheel applications listed in the compatibility section.

Will these lug nuts fit my car?

They are engineered to match wheels that require a 14x1.5 thread pitch and a 60° conical (acorn) seat. Check your vehicle’s factory lug nut specifications before purchasing to ensure compatibility.

• Thread pitch: 14x1.5
• Seat type: 60° conical (acorn)
• Socket size: 7/8" (22 mm)
• Overall length: 1.5" (38 mm), closed-end design

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

Mardarth lug nuts use a one-piece solid construction rather than a two-piece or capped design. One-piece nuts reduce the number of potential corrosion points and eliminate the internal cap seam that can trap moisture and rust.

• One-piece solid design for increased durability
• Salt-spray tested (72 hours) for improved corrosion resistance
• Chrome finish for an OEM-style look and easier cleaning
• Closed-end head helps keep threads cleaner than open-end nuts

How easy is installation and what tools do I need?

Installation is straightforward when the lug nuts match your wheel specifications. Use a 7/8" (22 mm) socket and a torque wrench to tighten to your vehicle manufacturer’s recommended torque specification.

• Required socket: 7/8" (22 mm)
• Recommended: torque wrench set to factory torque values
• Direct replacement for matching stock wheels—no adapter required
• Closed-end design prevents contaminants from entering the nut

What warranty and quality checks are included?

Mardarth provides a 1-year warranty covering manufacturing defects under normal use. The lug nuts are tested for corrosion resistance and built from high-quality materials, but always inspect fitment and finish upon receipt.

• 1-year limited warranty from Mardarth
• Salt-spray corrosion test: 72 hours
• Manufactured as a one-piece solid unit for longevity
• Customer support available for fitment or product questions

Who is this for: This kit is ideal for owners of compatible GM vehicles who need a full set of replacement lug nuts for stock-style wheels, prefer a closed-end acorn appearance, and want a durable one-piece chrome option. It suits DIYers replacing worn fasteners, professional mechanics servicing wheel assemblies, or anyone restoring the factory look on Camaro, Corvette, Equinox, Impala, and other listed models. Note: confirm your wheel’s thread pitch, seat type, and length match the Mardarth specifications before ordering to ensure proper fit.
