The WORKPRO 1/2" Drive Impact Lug Nut Socket (21mm) is an essential tool for automotive technicians and DIY enthusiasts who perform frequent tire rotations or wheel maintenance. Built for high-torque applications, this socket features a non-marring protective sleeve that prevents damage to expensive alloy wheels, though its specialized length may be bulkier than standard thin-wall impact sockets for extremely tight wheel wells.

Yes, it fits any standard 1/2-inch drive tool, though it is specifically optimized for impact wrenches.
No, the sleeve is specifically designed to be non-marring to protect sensitive wheel finishes.
Yes, as long as the fastener is a 21mm hex head and the application fits the 1/2-inch drive requirements.
The 86 mm measurement refers to the total length of the socket, providing deep access for recessed lug nuts.
It serves as both a high-visibility marker and a protective electrophoretic layer to prevent corrosion.
No, the pin and O-ring are typically sold separately or provided with your specific impact wrench.
Verify that the lug nut size is exactly 21mm and ensure there is no debris or excessive rust buildup inside the socket cavity.
If using a through-hole anvil, ensure you have properly installed a pin and O-ring to lock the socket into place.
The sleeve is designed to spin freely. This is normal and serves to minimize friction against the wheel surface during tightening or loosening.
To ensure optimal performance, verify that the 1/2-inch drive anvil of your impact wrench is compatible with the socket's locking mechanism. If your impact wrench uses a through-hole anvil, secure the socket using a standard pin and O-ring (not included) to prevent it from detaching during operation.
For maintenance, wipe the socket clean with a dry rag after use to remove grease and road grime. Although the electrophoretic coating is rust-resistant, storing the tool in a moisture-controlled environment will significantly extend its lifespan. Avoid using the protective plastic sleeve as a pry bar, as excessive side-loading can damage the plastic insert.
