Milwaukee 3/8"-24 NF Plug Tap

Milwaukee 3/8"-24 NF Plug Tap

The Milwaukee 49-57-5151 3/8"-24 NF Plug Tap is a precision-machined threading tool built to create or restore clean, accurate internal threads without turning your workpiece into an expensive paperweight. Designed for reliability in common shop applications, this plug-style tap handles through-hole threading with ease while its high carbon steel construction and black oxide coating keep it working longer and resisting corrosion. Clear laser-etched markings mean no squinting or second-guessing—because guessing thread size is a gamble nobody wins.
