When you are fabricating a custom bracket or repairing a stripped thread on a piece of heavy equipment, you need a tap that won't snap halfway through the job. The Walter 9/16-18 NF Plug Tap is built for the reality of the welding and fabrication shop. Made from tough High Speed Steel, this tap bites into metal and cuts clean, precise threads without binding or dulling prematurely. It is an essential tool for any metalworker dealing with fine thread fasteners.
This tap is a "Plug" style, which is the workhorse of the tapping world. It has enough taper at the tip to help you get it started straight in the hole, but it threads deep enough to be useful in almost any situation, especially through-holes in plate or tubing. The 9/16-18 size is a standard fine thread often found in automotive assemblies and precision machinery. Because it is made by Walter, you know the steel quality is top-notch, meaning you spend less time fishing out broken taps and more time finishing your project.
Using the right tool makes all the difference. This HSS tap handles heat better than cheap carbon taps, making it suitable for tougher materials like stainless steel and aluminum alloys commonly found in modern fabrication. Whether you are cleaning up existing threads after welding or cutting new ones in a fresh drilled hole, this tool provides the smooth, low-resistance cutting action you need. Pair it with a quality cutting fluid for even better results and longer tool life.
