OEM design & safety PLUS Beauty, Style, Precision & Durability!

The floating seat (2-piece) design provides optimum safety and performance. This protects against galling and helps prevent seized/difficult to remove bolts.

Precision manufacturing exceeds OEM requirements.

Beautiful chrome & black finish enhances the look of any wheel. The triple-nickel black & chrome plating is guaranteed for life not to chip, peel or rust.

Available in Wheel Installation Kits that include wheel locks and bulk boxes of 50.
 

Corrosion test

We tested our regular and bulge style acorn lug nuts against four competitors in a CASS (copper-accelerated acetic acid-salt spray) chamber. This test was developed by the American Electroplaters Society to measure the specific corrosion resistance of nickel-chromium platings. It involves subjecting plated parts to a salt solution at a specific temperature, pressure and length of time to emulate exposure to the elements. Accelerated tests like these are employed by car manufacturers to measure quality and performance.

A 22 hr. CASS cycle is considered to be equivalent to one year of exposure in Detroit weather conditions. Before each 22 hr. CASS cycle the lug nuts were installed and removed using a lug wrench to simulate normal use.

As you can see on these unretouched photos, our lug nuts look great even after 1, 3 and 5 years of exposure. If you were to wipe off the residue from the CASS test you’d have a hard time telling they weren’t new. Unlike the other brands, McGard lug nuts are designed and built to be used!
 

McGard invented its unique one-piece wheel lock for the automotive aftermarket in 1963. It functions like an existing lug nut, but requires a special key tool for removal. Our wheel lock is easy to use, yet provides a high level of wheel & tire security. It is also adaptable enough to allow for an unlimited number of different computer designed lock and key patterns.

McGard employs the same innovative design & high quality standards used in the production of wheel locks to manufacture chrome plated lug nuts. In-house plating technology and experienced personnel enables McGard to produce superior quality lug nuts in large volumes that are strong, safe, durable and exceed typical corrosion resistance standards.
