Quasi already a lifetime I switch to summer / winter tires on our cars themselves. As we become even older, I do that since this season with an electric impact wrenches and even impact these nuts. They serve their purpose perfectly: the white plastic sleeve protects the aluminum rim very effective, as well as to be rotatable about the actual nut, so you can run and keep the nut in it. The sizes - 17, 19 and 21mm - were just right for a VW Eos (studs) and a Hyundai SUV (nuts), so already cover a certain bandwidth from. And although I had to pick on individual bolts and nuts rather (some have 270 NM loosening torque is not enough!), Have the nuts which uncomplainingly taken part. The color coding is especially handy when summer and winter have different dimensions and constantly lying around two different nuts. Even if you can not expect much tool for 15 EUR - the exceeded my expectations here.
