Hi we don’t have the wheel nut for our volt. Does anyone know the type on the picture and where I could order another set?

 

that is a mcgard wheel lock nut. if you are missing just one....they are only sold as a set of 4. Any gm dealer or parts store can get them.approx 50. if you want just a factory oem non locking lug nut...dealer should have them for $10
