What's the 2009 Chevy Cobalt lug nut size?

The 2009 Chevrolet Cobalt uses an m12 X1.50 lug nut with a 19 mm hex size. Lug nuts are made of metal and are frequently designed and treated to prevent rust. However, over time they may develop rust as their protective coatings wear off or if they are neglected. Fortunately, since lug nuts are hardy so that they will hold the wheels of Your car in place, they can also stand up to some pretty serious rust-removal efforts.A torque wrench is a must have when tightening the lugs nuts. Youre never supposed to use an impact gun to put lug nuts on because theres no way to accurately control the torque thats being applied. Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud.
