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.

Completely useless
One lug nut is missing.

Do not purchase, they will strip out and you will not be able to remove your wheel
Attempted to use these to mount wheels with tight clearance in lug holes. Do not purchase these, get external spline lugnuts instead
