Review on Muteki 32905L SR Series Purple 12mm x 1.25mm SR48 Open End Lug Nut Set - (Set of 20) | High-Quality & Stylish Lug Nuts for Secure Vehicle Maintenance by Brent Henderson

Fits my race car with long ARP studs. I also drive on the road, mostly on the Autobahn, I don't drive in winter. The finish on them appears to be less than show quality, but it works well for my needs. I would not recommend them for use on salty roads as the finish will likely be completely ruined and the open end will expose your cleats. They fit Konig Helium and some old unknown braided rims. The manufacturer says to only use its socket and never use a punch. I have to remove them due to lack of time and energy. The socket supplied is ideally suited for these nuts. The 17mm deep Craftsman head fits but can get stuck, especially on impact. I'm assuming consumer grade sockets don't have a fine enough tolerance. The metal, especially the socket, seems softer than I've seen on other nuts and sockets. The hex head of the socket is chewed off. I'm used to gorilla style serrated lugs with a slotted socket. The Gorilla jack has held up better over the years with much more frequent use. The gorilla trim is also better preserved (I have the chrome and black kit on two cars). Unfortunately I was bored with the specific nut and wanted to use an open end nut for my new studs. This one fits the bill but doesn't completely eliminate the need for an outlet. I used them over two weekends.
