Milwaukee 49-66-6124 3/8 in Drive 11/16 in Deep Impact Socket

Product Description

The Milwaukee Electric Tool Corp 49-66-6124 is a deep 6-point impact socket designed for heavy-duty fastening applications. Built as part of the Shockwave Impact Duty line, it features a 3/8 inch drive and a 11/16 inch opening with a deep-well profile that reaches recessed fasteners standard sockets cannot access. The 6-point geometry reduces rounding on hex fasteners compared to 12-point designs, making it a reliable choice for high-torque impact driver and impact wrench use. Licensed electricians, HVAC technicians, plumbers, and general trade professionals use this socket for production and service work.

This socket is suited for residential and light commercial trade work where a 3/8 inch drive impact wrench or ratchet is the standard tool. The deep-well design accommodates longer bolt studs, threaded rod, and recessed fastener applications common in electrical panel work, mechanical equipment installation, and plumbing fixture mounting. It is sold individually as a single unit and is compatible with standard 3/8 inch drive impact wrenches and ratchets.

• 11/16 inch opening covers a common fastener size across electrical, mechanical, and plumbing work
• Deep-well design reaches recessed fasteners and long threaded studs

Compatibility

Installation Notes

A licensed trade professional or experienced technician should select the correct socket size before applying torque to avoid fastener damage. Always confirm the drive size of the tool matches the 3/8 inch square drive of this socket before use. Do not use impact sockets with hand-ratchet-only tools beyond their rated torque capacity. Inspect the socket for cracks or wear before each use and replace if deformation is visible.
