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 this 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 hour CASS cycle the lug nuts were installed and removed using a lug wrench to simulate normal use.
