This is the wrong fit (not perfect or totally secure, but still works) for my drives. The description clearly states the specs, but *I* wasn't quite sure what I needed; Hence my mistake and it would be wrong to return it. My problem is the glans, the outer width of the taper area (22mm). I needed at least 23mm because that's what my specific rim requires. However, they appear to be of good quality and workmanship. The only reason I didn't give it 5 stars is the warning not to use an electric/impact wrench. This is a problem as all wheels are eventually exposed to impact tools. Two reasons I can think of why you wouldn't do this: 1) the finish isn't durable; or 2) the taper width is too narrow. In summary and most importantly, I needed a 14x1.5 13/16 head, not 3/4. The difference is that the width of the constriction is larger on the 13/16.
