The Milwaukee Tool SHOCKWAVE Impact Duty 1/2 Drive Lug Nut Wheel Sockets are designed for tire installations and removals. The sockets feature a durable, non-marring sleeve to protect rims during tire changes while ensuring the durability of the sleeve. With this Armor-Guard sleeve, each socket protects against crackling or shredding. The lasting-protection sleeves are color-coded gray and red to distinguish between metric and SAE sizing and include stamped, ink-filled markings on the socket for easy size identification. The sockets also have a plastic insert, preventing the lug nut from marring while being used. Constructed with thin walls, the sockets are optimized for users to access the tight spaces around lug nuts.
