Walter 5/8-11 NC HSS Plug Tap for Steel and Stainless

Reliable Tapping for Tough Metal Fabrication

When you're in the middle of a fabrication job or a critical repair, you need a tap that won't snap or dull halfway through the hole. The Walter 5/8"-11 NC Plug Tap (03B102) is built for exactly that kind of reliability. Made from heavy-duty High Speed Steel, this tap bites into metal and cuts clean, precise threads without fighting you all the way. It's designed to handle the materials welders and fabricators work with every day, from standard mild steel to gummy aluminum and tough stainless steel.

The "Plug" style design features a slight taper over the first 3 to 5 threads. This is the sweet spot for general-purpose tapping—it starts easily enough but gets to full thread depth quickly, making it perfect for open-ended (through) holes. If you are cleaning up splatter-damaged threads or tapping a new hole for a heavy bolt, this tool clears chips efficiently and maintains its edge. The ground threads reduce drag, which means less heat buildup and less chance of the tap binding up in the workpiece.

Don't settle for cheap carbon taps that lose their edge after a few holes. This Walter HSS tap is tempered for toughness, giving you the confidence to apply the necessary force without fear of shattering the tool. It fits standard tap handles and is ready to work as hard as you do. Whether you are tapping a mounting plate, repairing a machine part, or fabricating a custom bracket, the Walter 03B102 delivers professional results that hold tight.
