Milwaukee Tool 45-34-2121 Deep Hand Socket 1/2 Drive 6 Point

Product Description

The MILWAUKEE TOOL 45-34-2121 is a deep hand socket designed for use with 1/2 inch square drive ratchets and breaker bars. It features a 6-point internal geometry that maximizes contact with fastener flats, reducing the risk of rounding under torque. The chrome finish provides corrosion resistance for long service life in shop and field environments. This socket is suited for professional mechanics, maintenance technicians, and trade contractors who require reliable metric fastener engagement in deep-reach applications. It is not tether capable and is sold as a single unit.

This deep socket is used in residential and commercial maintenance, mechanical service, and industrial applications where standard-length sockets cannot reach recessed fasteners. The 1/2 inch drive size makes it compatible with common ratchets, torque wrenches, and impact-ready adapters found in professional tool kits. Its metric sizing and standard-length profile suit a wide range of fastener configurations encountered in HVAC equipment, plumbing assemblies, and general mechanical work.
