Review on McGard 64012 Chrome Bulge Cone Seat Lug Nuts (M12 x 1.5) - 4-Piece Set: Secure & Stylish Wheel Fastening Solution by David Miller

Ring nuts are a much better quality than stock Ford nuts. I don't have to deal with swollen nutshells every time I take a tire off while owning my 2005 Ford Focus ZX4 ST, it's worth the replacement price. The only thing to worry about is a little rusting in 2 of the 4 packs I bought - possibly from old stock - which others have mentioned in their reviews. I didn't deduct a star because I knew that might be the case from other reviews and because they are so much better than OEM. Buy and enjoy!
