Review on McGard 65457BK SplineDrive Wheel Installation Kit (M12 x 🔧 1.5 Thread Size) - Black, Ideal for 4 Lug Wheels by Justin Bradford

This kit contains a great set of small diameter nuts and locks. The quality seems to be very good. I've had to unscrew the nuts half a dozen times now, and the black finish is just as polished as when I bought it. The split-piece design works very well, allowing the seat (the surface that comes into contact with the wheel) to remain stationary once tightened. This will help you get a torque much closer to correct torque the first time (always double check). They look great on darker gunmetal wheels (I have Kosei K1 TS wheels). A bit pricey but definitely the best when you need small diameter lock nuts.
