Milwaukee Tool 49-66-6288 Impact Socket 1/2 in 27mm

Product Description

The MILWAUKEE TOOL 49-66-6288 is a 1/2 inch drive, 27mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Constructed from steel with a black phosphate finish, this standard-length socket resists corrosion and withstands the high-torque demands of impact tooling. The non-sparking construction makes it suitable for environments where ignition risk is a concern. At 0.65 pounds, it delivers a solid, durable feel without adding unnecessary bulk to a tool bag or socket set.

This socket is suited for residential and commercial mechanical work, including HVAC equipment installation and service, plumbing rough-in fastening, and general trade applications where a 27mm hex fastener is encountered. The standard-length profile fits most accessible fastener locations without the need for an extension. The non-sparking rating makes it appropriate for use near gas lines or in environments with flammable vapors, a consideration relevant to HVAC and plumbing professionals working around fuel-burning equipment.

Key Features

• 1/2 inch drive fits standard impact wrenches and ratchets
• 27mm 6-point socket geometry reduces fastener rounding under high torque
• Non-sparking construction rated for use in ignition-sensitive environments
• Steel construction with black phosphate finish for corrosion resistance
• Standard-length profile for everyday fastener access
• Not insulated — confirm appropriate PPE and lockout/tagout procedures before electrical work

Compatibility

Designed as a standard OEM-style 1/2 inch drive impact socket compatible with 1/2 inch drive impact wrenches, torque wrenches, and ratchets accepting 27mm hex fasteners.

Installation Notes

This socket is installed by HVAC technicians, plumbers, electricians, and general mechanical tradespeople using 1/2 inch drive impact or hand-drive tools. Always verify the tool drive and fastener size match before applying torque. Shut off power, gas, or water supply as required by the work area before servicing equipment. Note that this socket is non-insulated and should not be used on energized electrical components.
