Keep your wheels torqued down securely with the Dorman - Autograde Wheel Lug Nut 611-580, a one-piece carbon steel replacement that drops in on the 2011-2012 Chevrolet Colorado and 2011-2012 GMC Canyon. This OE FIX nut carries M12-1.50 threads, a dome top, an 18mm hex, and a 62mm length to install like the original hardware on the listed applications.

The factory lug nuts on certain vehicles use a failure-prone two-piece design where a thin outer veneer can be damaged with repeated use; when moisture works underneath, the cover can bulge and deform, making the nuts difficult or impossible to remove without damaging the wheel. This Dorman replacement addresses that with a solid one-piece build.

  • One-piece design: intended to improve durability and longevity versus the two-piece factory nut that often warps over time.
  • Corrosion resistant: with no outer veneer, there's no cover for moisture and rust to bulge and deform.
  • Thoroughly tested: subjected to proof load, salt spray, hardness, and thread check testing to meet strict standards.
  • Quality engineering: designed in the United States and backed by decades of aftermarket experience.

Frequently Asked Questions

What vehicles does this lug nut fit?

It fits the 2011-2012 Chevrolet Colorado and 2011-2012 GMC Canyon. See the Buyer's Guide tab to confirm your exact vehicle.

What are the specifications of this lug nut?

It's a dome-top nut with M12-1.50 threads, an 18mm hex, and a 62mm length, built as a one-piece carbon steel design.

Why is a one-piece design better than the factory nut?

The two-piece factory nut can warp and its veneer can bulge if moisture gets underneath, making removal difficult. The one-piece build is intended to improve durability and longevity.

Is this lug nut corrosion resistant?

Yes. By removing the outer veneer of the OEM design, there's no cover for moisture and rust to get under and cause it to bulge or deform.

Has this part been tested?

Yes. It has undergone proof load, salt spray, hardness, and thread check testing to meet strict standards.
