Milwaukee Tool 49-66-7830 Lug Nut Socket Set 3 Piece

Product Description

The MILWAUKEE TOOL 49-66-7830 is a 3-piece metric lug nut socket set built for automotive and light-duty truck wheel service. The set covers three of the most common lug nut sizes — 17mm, 19mm, and 21mm — all on a 1/2 inch drive. Each socket is deep-well and thin-walled, allowing clearance in tight wheel assemblies where standard-wall sockets bind against the wheel hub or caliper. The sockets are steel construction with a gray finish and a 6-point contact geometry that reduces rounding on fasteners under high torque. The set ships on a socket rail for organized storage and quick retrieval at the vehicle.

This set is intended for automotive service professionals, fleet mechanics, and tire technicians who rotate, mount, or torque wheels regularly. The thin-walled design is particularly useful on passenger vehicles and light trucks where aftermarket wheels or closely spaced wheel hardware limits tool access. The 1/2 inch drive pairs with impact wrenches and breaker bars commonly used in bay and roadside service. The deep-well depth accommodates extended lug nut shanks found on many OEM and aftermarket wheel applications.

Compatibility

Designed for use on passenger vehicles and light trucks requiring 17mm, 19mm, or 21mm metric lug nuts driven by a 1/2 inch drive tool.

Installation Notes

Wheel fastener service should be performed by a qualified mechanic following the vehicle manufacturer's torque specifications. Secure the vehicle on a level surface with the parking brake engaged and use appropriate wheel chocks before removing or installing lug nuts. Always verify final torque with a calibrated torque wrench after using an impact tool. Inspect sockets periodically for cracks or wear and remove from service if deformation is observed.
