Meet the Milwaukee 13 mm X 3/8 in. drive Metric 6 Point Standard Deep Socket—an essential tool for anyone tackling metric fasteners in tight spaces. Built for daily use in repair shops, garages, and home projects, this socket combines durability, reach, and a secure grip you can rely on.
Crafted from high-quality Chrome Vanadium steel and finished in a protective chrome coating, it stands up to repeated torque and resists corrosion. The 6-point interior design delivers a more secure contact with hex fasteners, reducing cam-out and preventing rounding on stubborn bolts.

This socket is ideal for automotive work (engine compartments, engine mounts, and other metric fasteners), motorcycle maintenance, equipment repair, and household projects where a reliable long-reach tool is needed. Its deep design helps you work with recessed bolts and long studs without needing excessive clearance, while the 13 mm size ensures compatibility with a wide range of metric hardware.
Why choose this Milwaukee deep socket over others? It pairs a robust Chrome Vanadium core with a precise 6-point profile and a long, deep reach that minimizes the need for adapters or extensions in cramped spaces. The result is faster, more consistent torque application and fewer stripped fasteners—saving time and reducing frustration on demanding jobs.
Practical tips: pair the 13 mm deep socket with a 3/8 in ratchet and, when working in tight spaces, use a shallow-angle extension sparingly to maintain control. If you’re dealing with stubborn, rusted bolts, apply a penetrating lubricant, allow time to dwell, then reattempt with a steady, medium torque rather than forcing the fastener. This keeps the socket and fastener in good condition for longer.
