Review: Perfect - Just what I was looking for. High quality and good price. I dislike the look of standard “tuner lugs” these have a clean appearance and fit just as well. Most splined lugs can be removed by a thief with a standard socket, the hex adds a bit of security without the hassle of keeping track of a special key. They are steel and have a lot of material around the bore. The specs in the description are totally accurate. I trust them to keep the wheels on the hub 100p.
