These are amazing, you can feel the quality when you hold them in your hands. Twist until the end with a smooth hand. Ideal for extended arp cleats if you don't want to use an open end. Note: I use 10mm spacers. That might be the reason I didn't get to the bottom. But there is still enough space. Almost 2 inches in them for rivets. There is no rust on this kit as other reviews have said, but if it was there it would probably be inside, a quick press would do it. The paint is also of good quality. True, they are simply thrown into a bag and placed in a box, while hanging there, maybe there are scratches on it. All in all a great set and looks very good,
