Lug Nuts
Description
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!
