Use these dedicated sockets every time you remove damaged/distorted lug nuts with steel caps. These lug nuts become distorted due to improper leverage using the factory supplied tire iron. Removing over-torqued lug nuts during extreme cold/heat also distorts lug nut cap. Dual flip 1/2″ drive impact socket design. Comes in a blow molded carrying case. Includes 3 lug nut removal tools and an Extractor Punch.
