Milwaukee Tool 49-66-7806 Deep Wheel Socket 1/2 in 21mm

Product Description

The MILWAUKEE TOOL 49-66-7806 is a 21 mm deep lug nut wheel socket designed for tire service and wheel installation work. Built on a 1/2 inch drive, this 6-point deep socket features an ARMOR-GUARD sleeve — a premium, durable plastic sleeve engineered to protect wheel rims and finished surfaces from marring during tire changes and wheel removal. At 1.22 inches overall length, it delivers the depth needed to fully engage lug nuts without contacting the rim face. Automotive technicians and tire service professionals will find this socket suited for both hand-torque and impact-adjacent wheel service workflows where rim protection is a priority.

This socket is intended for automotive wheel service applications, including passenger vehicle and light truck tire changes. The non-marring sleeve makes it appropriate for use on alloy wheels and finished rims where bare metal sockets risk cosmetic damage. It is well-suited for shop environments handling high-volume tire rotations and seasonal wheel swaps, as the ARMOR-GUARD sleeve is rated to withstand repeated installation and removal cycles without degrading protective performance.

Key Features

• ARMOR-GUARD non-marring plastic sleeve protects alloy and finished wheel rims during tire service

Compatibility

Designed for use with 21 mm lug nuts on passenger vehicles and light trucks where rim protection is required. Fits standard 1/2 inch drive ratchets, breaker bars, and torque wrenches.

Installation Notes

Installation and removal of wheel lug nuts should be performed by a qualified automotive technician following the vehicle manufacturer's torque sequence and specifications. Always secure the vehicle on a stable lift or jack stands before beginning wheel service. Verify the socket seats fully on the lug nut before applying torque to avoid fastener damage. Do not use this socket with high-speed impact drivers that may damage the protective sleeve.
