These SKCOAUTO M14x1.5 lug nuts are a 24-piece OEM-style replacement set engineered to fit many GM 6‑lug factory wheels with a 60° conical seat and closed-end design.

If your vehicle uses M14x1.5 lug nuts and you want an exact OE-style swap, this kit offers the correct thread pitch, hex size and seat geometry for a wide range of Chevrolet, GMC and Cadillac models. Machined from SCM steel with a one-piece solid construction and a black finish, these lug nuts match factory fit and appearance while resisting corrosion. The set includes 24 lug nuts — ideal for axles or spare coverage — and is backed by a one-year guarantee.

Which vehicles and wheels will these lug nuts fit?

These lug nuts are built to replace original equipment on many GM trucks and SUVs with 6-lug wheels. Fitment covers specific model years and trims where the factory uses M14x1.5 thread pitch and a 60° bulge conical seat.

• Cadillac: ENCLAVE 2008–2023, ESCALADE 2006–2024, LYRIQ 2023, XT5 2017–2020, XT6 2021, XTS 2014–2019

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

SKCOAUTO uses a one-piece solid construction to avoid the failure modes that affect capped or two-piece lug nuts. A one-piece nut eliminates internal caps and seams where moisture and salt can cause rust, making maintenance easier over time.

• Solid SCM steel body for improved strength and durability
• Tested 72 hours salt spray for corrosion resistance
• Closed-end design prevents debris ingress and protects studs
• Black finish for factory-matching appearance

What are the exact specifications and installation details?

These lug nuts are sized and shaped to match OE dimensions so they thread on and seat properly without modification. Confirm your vehicle uses M14x1.5 pitch and 60° conical seat before purchase.

• Thread pitch: M14 x 1.5; Hex: 7/8" (22 mm)

What warranty and long-term protections are provided?

The set includes a one-year guarantee and passes industry salt-spray testing to help resist rust and corrosion during typical use. While the finish improves longevity, routine inspection and correct torque are recommended for safe operation.

• 72-hour salt spray tested to evaluate corrosion resistance
• One-year limited warranty for workmanship and defects
• Closed-end design reduces exposure of threads to elements
• Designed as direct OE-style replacements — torque to factory spec
