Will these lug nuts fit my Chevy or GMC vehicle?

These lug nuts use an M14x1.5 thread and a 60° conical seat designed for aftermarket wheels that require a 23mm flange limit. They are intended as replacements for many common GM models but only fit wheels that accept M14x1.5 conical-seat hardware.

• Compatible with Chevy Avalanche, Blazer, Colorado, Equinox, Express 2500, Silverado 1500/2500/3500, Suburban, Tahoe, Traverse
• Compatible with GMC Acadia, Canyon, Savana 1500, Sierra 1500/2500/3500, Terrain, Yukon, Yukon XL
• Measure flange limit (max 23mm) and confirm conical 60° seat on your aftermarket wheels

How durable and corrosion-resistant are these nuts?

MIKKUPPA treats the lug nuts to a thorough 72-hour salt spray process and an infrared drying step so the chrome-like finish bonds tightly to the metal. The nuts are cold-forged, heat treated and feature a thick coating to resist rust, chipping and wear under road conditions.

• 72-hour salt spray resistance for improved oxidation protection
• Infrared-dried paint integration reduces peeling and flaking
• Cold-forged, heat-treated steel for higher strength and anti-stripping

What is the design and size specification of each nut?

Each one-piece lug nut is a closed-end bulge style with a 60° conical seat, measuring 45mm (1.8") in overall length and a 19mm (3/4") hex drive. The nut body is approximately 23mm wide, offering an extended shank for deeper thread engagement on compatible wheels.

• Thread: M14 x 1.5
• Overall length: 45mm (1.8") with 23mm wide body
• Drive size: 19mm (3/4") hex; closed-end bulge/conical 60° seat

How do I install and care for these lug nuts?

Installation follows standard lug nut torque procedures for your vehicle and wheel type; use a properly sized 19mm socket and torque wrench to the manufacturer-recommended spec. Routine inspection and cleaning will preserve finish and function, and the one-piece design reduces the risk of loosening compared with two-piece sets.

• Tighten with a 19mm (3/4") socket and follow vehicle wheel torque specs
• Inspect periodically for corrosion or stripped threads; clean with mild soap and water
• Set of 24 covers most full-wheel replacements and spare hardware needs
