Experience reliable torque and a confident grip with the Milwaukee 5/16 in. SAE 6-Point Deep Socket, designed for serious hand-tool lovers who demand precision in tight spaces. This compact, 1/4 in. drive socket is built to reach fasteners deep inside assemblies where standard sockets can’t tread, making it a go-to for automotive, motorcycle, and equipment maintenance.
Why this 5/16 in. SAE deep socket stands out
-
Six-point hex design → maximum bite on 5/16 in. fasteners, reducing rounding and slippage under torque.
-
Deep reach with a 2.559 in. length to access recessed nuts on engines, suspensions, and hard-to-reach components.
-
1/4 in. drive compatibility with compact ratchets and adapters for tight workspaces without sacrificing control.
-
Chrome Vanadium steel construction delivers lasting strength and fatigue resistance for daily shop use.
-
Polished chrome finish offers corrosion resistance and easy cleanup after grease-filled jobs.
-
Carded packaging keeps the tool organized and ready for display or travel.
-
Not impact rated—designed for hand-rle, precision tightening rather than impact use.
Real-world scenarios and best-fit applications
Ideal for automotive maintenance where fasteners sit deep inside a crowded engine bay, such as securing exhaust hangers, engine brackets, or suspension components. It’s also a dependable choice for motorcycles, lawn equipment, and machinery that require a lengthier socket to reach through guards or panels. The 6-point design makes it especially forgiving when dealing with slightly worn fasteners, helping you avoid cam-out and finished work that looks pristine.
How this socket fits into your toolkit
Pair it with a 1/4 in. drive ratchet or a compact wrench for a nimble setup in cramped spaces. Its durable chrome vanadium composition means you’ll get consistent performance across multiple jobs without premature wear. For best results, use with a properly sized 5/16 in. nut or bolt and avoid using with high-torque impact tools to preserve the finish and socket geometry.
What’s included
1 socket in carded packaging, ready to hang on a pegboard or drop into a tool tray for quick access on the job.
