Mardarth 14mm x1.5 OEM-Style Wheel Lug Nuts — 32‑Piece Zinc‑Gold Set, 7/8" Hex, 60° Cone

Mardarth 32-piece set of 14mm x 1.5 OEM-style bulge acorn lug nuts built to replace factory hardware on Silverado, Sierra and other 8-lug heavy-duty GM trucks.

These lug nuts are made to match original equipment fitment for many Chevrolet and GMC 2500/3500 series trucks and vans. Each nut uses a 60° conical (cone) seat with external dual-thread design, a 7/8" hex, and a zinc-gold finish that resists corrosion. The kit includes 32 nuts so you can service both front and rear wheels or keep spares on hand.

Will these lug nuts fit my Silverado or Sierra?

They are designed to fit vehicles that use 14mm x 1.5 inner thread and a cone-style seat. This set matches factory dimensions including the 7/8" hex and overall length, making them a direct replacement for many GM 8-lug stock wheels.

• Inner thread: M14 x 1.5 (factory spec)
• Seat type: 60° conical (bulge acorn)
• Hex size: 7/8" (22mm) for standard lug wrenches
• Overall length: 1.12" (28.5mm) and 26.5mm diameter

How durable and corrosion-resistant are these nuts?

Manufactured from high-quality materials and finished in zinc-gold, the nuts undergo corrosion testing to extend service life. The supplier reports 72-hour salt spray testing to simulate prolonged exposure and improve rust resistance compared with plain steel hardware.

• Zinc-gold finish for enhanced corrosion protection
• 72-hour salt spray testing for simulated longevity
• Solid construction intended for heavy-duty wheel loads

What makes this kit a direct replacement for OEM parts?

The dimensions and thread pitches mirror common factory parts so these lug nuts will fit without modifications. They’re produced to replace several OE part numbers and work with original stock 8-lug wheels, providing a straightforward swap for maintenance or restoration.

• Dual-thread external design matching OE specifications
• Compatible with many OE part numbers for cross-reference
• Sold as a 32-piece kit to cover most wheel configurations

How should I install and torque these lug nuts?

Installation is the same as other OEM lug nuts: thread by hand first, then tighten progressively in a star pattern to the vehicle manufacturer’s torque specification. Using the correct 7/8" (22mm) socket and a calibrated torque wrench helps ensure safe, even clamping.

• Hand-start each nut to avoid cross-threading
• Tighten in a star pattern for even seating
• Use manufacturer-recommended torque values and a 7/8" socket
