Locking Lug Nut Set for Trailers (4 Nuts, 1 Key) 1/2" Stud

Thread: 1/2 - 20
Depth: 1.30"
Hex (Socket Size): 13/16"
Salt Spray Tested: Yes

Each set of locking lug nuts comes with (4) lug nuts and a Key. The key is needed to remove and install the lug nuts. They are tuner style lug nuts, so they can be used with any aluminum wheels. They use a 60 degree seat; which is fairly standard in the trailer industry.

We tested our locking 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.
