These nuts are very worn. It looks like they're nickel plated anyway, making glitter their only saving grace. The closed ends have tool marks that differ from one nut to the next, giving the appearance of an inferior KIA factory. The wrench is pretty thin-walled and I don't think it will withstand bludgeoning weapons. They are longer than the OEM and weigh 0.1 ounces less than the OEM. They get the job done, but you have to use hand tools to keep the key socket from breaking or cutting off. It might be a good idea to buy another wrench, just in case, and coat the threads with non-stick compound. Probably best for cars and definitely not for trucks or vans. Knowing what I know now, regardless of Revain's installation recommendations, I would choose a different brand. Any nut with a 12mm x 1.2 boss will work as long as it has the required 60Β° taper in the seat base for the same installation recommendations.
