Thank you. You have rated this product.
Tough enough for an impact gun, yet super light. Less than half the weight of steel lugs. This design is as light and strong a design as possible, just like the 6UL. Notice no 90 angles, chamfers and radiuses everywhere = no stress risers. Will not rust. 19mm hex is not a random size. Much stronger than 17mm and far easier to get a socket onto that 21mm lugs. If you're taking wheels on and off a lot for racing these details matter!
