Mardarth 14x1.5 Chrome Lug Nut Set 20pc — 1.5" Closed-End Acorn Seat, 7/8" Hex

Mardarth 20-piece 14x1.5 chrome acorn-seat lug nut set — 1.5" long, closed-end, 7/8" (22mm) hex — for many Chevy models and compatible aftermarket wheels.

These lug nuts are a complete 20-piece replacement set designed for vehicles that use 14x1.5 thread pitch lug nuts with a conical (acorn) seat and 1.5" overall length. Finished in chrome and produced as a one-piece solid design, they replace worn or missing hardware and give wheels a polished, corrosion-resistant look. The set includes hardware compatible with many Camaro, Corvette, Equinox, Impala, Silverado, Tahoe and other GM model years; confirm fitment for your specific wheel before purchase.

How do these Mardarth lug nuts fit my vehicle and wheels?

Fit is determined by thread pitch, seat type and nut length: these are 14x1.5 threads with a 60-degree conical (acorn) seat and 1.5" overall length. They are intended for wheels that accept acorn-seat lug nuts and may not work with factory wheels that require different OE-style nuts.

• Thread pitch: 14x1.5
• Seat type: conical/acorn, 60°
• Length: 1.5" (38 mm) overall
• Hex size: 7/8" (22 mm) socket required

Are these lug nuts durable and corrosion resistant?

The nuts are manufactured as a one-piece solid construction to reduce the risk of internal rust and loosening that can affect two-piece or capped designs. They have been subjected to corrosion testing and are chrome plated for added protection and visual appeal.

• One-piece solid construction for improved longevity
• Chrome finish for corrosion resistance and shine
• Salt-spray tested to help resist rusting

How easy is installation and what tools are needed?

Installation is straightforward if the wheel accepts 14x1.5 acorn seat lug nuts. Use a 7/8" (22 mm) socket or wrench and torque to the vehicle manufacturer’s specified wheel nut torque. These are closed-end nuts, so they thread fully onto the stud without exposing the stud end.

• Tool required: 7/8" (22 mm) socket or wrench
• Closed-end design protects studs from dirt and corrosion
• Torque to factory-recommended spec for your vehicle/wheel

Which models are commonly compatible with this set?

This 20-piece set is commonly used on a range of GM models that employ 14x1.5 acorn-seat lug nuts, particularly with many aftermarket wheels. Always verify your wheel seat type and thread pitch before ordering.

• Common fits include Camaro (2010–2022) and Corvette (2020–2023)
• Also compatible with Equinox, Impala, Malibu, Silverado, Tahoe and various GM trucks and SUVs listed in specifications
• May not fit certain OE factory wheels—confirm wheel specs

Who is this for? This Mardarth set is aimed at car owners and mechanics replacing multiple lug nuts at once — particularly those upgrading worn, corroded or missing hardware on compatible GM vehicles or retrofitting aftermarket wheels that accept 14x1.5 acorn-seat nuts. If you need a full 20-piece chrome set with a closed-end, one-piece design and standard 7/8" hex, this kit offers a ready replacement with a corrosion-resistant finish and a one-year warranty for peace of mind.
