Excellent nuts, well made, tapered fit very well (taper machined very concentric to thread). The only issue I have is the weight difference between the lug nuts and the locks. Each nut weighs 54g (1.9 oz) and wheel lock weighs 71g (2.5 oz); It's too big a difference and it unbalanced my bike. So I had to buy a set of 4 regular nuts separately, plus I can't use a wheel lock. McGard must find a way to redesign his wheel locks to match the weight of regular nuts.
