SKCOAUTO M14x1.5 Lug Nuts 24pc Chrome — Closed-End 60° Acorn for Silverado/Tahoe

If you need a full set of wheel fasteners that match OE thread pitch and seat style, this kit offers 24 chrome-plated, heat-treated lug nuts sized for GM 14x1.5 applications. The one-piece solid construction is made from 10.9-grade steel and finished with corrosion-resistant chrome after passing a 72-hour salt spray test. The closed-end design protects studs from contamination while the 60-degree acorn seat fits factory tapered-wheel pockets for secure clamping.

Will these lug nuts fit my Silverado, Tahoe, or Suburban?

Yes—these lug nuts are manufactured to match the common M14x1.5 thread pitch and 60° acorn seat used on many GM full-size trucks and SUVs. They are intended as like-for-like replacements for factory nuts and for use with compatible aftermarket wheels that accept a 60° acorn seat.

• Thread pitch: M14 x 1.5
• Hex size: 7/8" (22 mm)
• Overall length: 1.77" (45 mm)
• Seat type: 60° acorn (tapered)

How durable and corrosion-resistant are these wheel nuts?

The nuts are forged from 10.9-grade, heat-treated steel for high tensile strength and fatigue resistance under wheel clamping loads. Chromed exterior plating is applied and the parts have been salt spray tested for 72 hours to reduce surface corrosion during regular road exposure.

• Material: 10.9-grade heat-treated steel for strength
• Finish: chrome plating for rust resistance and polished appearance
• Testing: 72-hour salt spray corrosion testing
• Design: closed-end bodies to keep threads cleaner

Which OE numbers or part sets do these replace?

This 24-piece kit is designed to replace many common GM lug nut part numbers, making it simple to match OEM hardware when refurbishing wheels or replacing lost/damaged nuts. It’s supplied as a complete set so you can change all wheel fasteners at once for consistent fit and finish.

• Replaces OEM numbers such as 6509422AA, 6595203, 9596070 and others
• Sold as a full set of 24—enough for four wheels plus spares
• Closed-end acorn shape matches factory tapered seats

How should I install and maintain these lug nuts?

Install using a 7/8" (22 mm) socket and torque to the vehicle manufacturer’s recommended specification to avoid over- or under-tightening. Periodically check for corrosion or loosening, especially after seasonal use or long storage; the closed-end design helps reduce the need for thread cleaning.

• Use correct torque values from your vehicle manual
• Inspect lug nuts after initial drive following installation
• Clean and re-torque during routine wheel maintenance
• Avoid impact guns for initial seating when possible

Who is this for: This 24-piece SKCOAUTO lug nut set is aimed at owners and technicians working on Chevrolet Silverado, GMC Sierra, Tahoe, Suburban, Yukon, Escalade, and other GM models that use M14x1.5 threads and 60° acorn seats. It’s well suited to anyone replacing a full set for refurbishment, upgrading to chrome hardware, stocking a shop, or ensuring a matched set after wheel or stud service. The parts provide OEM-style fit, closed-end protection for stud longevity, and a chrome finish for a factory look without the premium OE price.
