Not worth the small savings to endanger yourself and everyone around you, the threads are absolutely awful, the difference between 17 year old factory lugs is very noticeable. I could feel my truck pulling sideways while driving, upon inspection I noticed one of my wheel studs was shearing due to excessive play in those cheap nuts, now I need to replace at least one set of wheel studs, the pictures say it all I'm an aircraft mechanic and installed them to OEM torque specs and I'm telling you the price isn't worth the risk when it comes to something that will hold your car's wheels. Luckily I have a spare car while I wait for a quality replacement and set of wheel bolts. Don't put yourself or others on the road at risk to save a few bucks. You will return as soon as possible.
