Cheap, they're small, strong, light and made of steel. Don't be fooled by other lightweight aluminum nut sets. They clog your rivets over time. They are made of steel and will go a long way. The two downsides to these lug nuts is that you can hit the socket to loosen it. 16mm should fit. Also, the key is very easy to find. Bad news if you really want to protect your wheels. The good news is that you can get a key at most tire shops in case you lose yours.
