Milwaukee Tool 45-34-8021 3/8 Drive 6 Point Metric Socket

Product Description

The MILWAUKEE TOOL 45-34-8021 is a standard hand socket designed for use with 3/8 inch square drive ratchets and extensions. Built for metric fastener applications, it features a 6-point contact geometry that reduces the risk of rounding fastener heads under torque. The chrome finish provides corrosion resistance for long service life in demanding shop and field conditions. At 0.2 pounds, this socket is lightweight and suited for everyday use by HVAC technicians, plumbers, electricians, and other trade professionals who require dependable hand tools for mechanical assembly and service work.

This socket is appropriate for residential and commercial service environments where metric fasteners are common. Typical applications include equipment installation, panel work, and mechanical service tasks requiring a 3/8 inch drive tool. The standard length profile fits most accessible fastener locations without the bulk of a deep socket. It is packaged as a single unit and is well suited for replacing a worn socket or supplementing an existing set.
