The WORKPRO 1/2″ Drive 21mm Deep Thin Wall Lug Nut Impact Duty Socket is built for car wheel service where space is tight and protection matters.

For cleaner, safer wheel work, it includes a removable transparent protective sleeve to help prevent scratches on wheels, plus an inner white plastic insert that helps protect lug nuts and reduce friction. When you need extra clearance, you can remove the sleeve to make the socket slimmer—useful for narrow lug openings and tight wheel wells.

Pair it with a 1/2″ drive torque wrench for precise installation and removal. Laser-etched size markings and color-coded coating make it easy to grab the correct socket quickly.
