Milwaukee Tool 49-66-7840 Socket Set 7 Pc 1 in Drive

Product Description

The MILWAUKEE TOOL 49-66-7840 is a 7-piece fractional inch socket set designed for use with 1-inch drive impact wrenches and adapters. The set covers sizes from 13/16 inch to 1-1/4 inch and includes a mix of thin wall extra deep, deep, and standard 6-point sockets finished in black phosphate for corrosion resistance. Stamped and ink-filled diameter markings provide wear-resistant size identification. The SHOCKWAVE Impact Duty construction makes this set well suited for high-torque fastening applications in heavy equipment maintenance environments where standard sockets may not fit within tight clearances.

This socket set is built for heavy equipment maintenance, fleet service, and wheel service work requiring a 1-inch drive. The mix of socket depths — standard, deep, and thin wall extra deep — addresses the range of fastener access situations common in commercial vehicle, agricultural, and construction equipment service. Licensed HVAC technicians, equipment mechanics, and trade professionals working on large mechanical assemblies will find the set covers the common large-fastener sizes encountered in that work. The included case keeps sockets organized and protected between jobs.

Installation Notes

Equipment mechanics and service technicians should ensure the drive tool is powered down or depressurized before changing sockets. Verify the socket seats fully on the drive detent before applying torque. Inspect sockets for cracks or deformation before use on high-torque fasteners. Use within the rated capacity of the drive tool in use.
