Walter 1/2-13 NC HSS Plug Tap for Steel and Stainless

Reliable Taps for the Fabrication Shop

Every welder knows that fabrication isn't just about joining metal—it's often about assembly and repair, too. The Walter 1/2-13 NC Plug Tap (03B082) is a must-have tool for your shop's bench. When you need to tap a hole for a bolt or clean out a thread that's been damaged by weld spatter or corrosion, this high-quality High-Speed Steel (HSS) tap gets the job done right the first time. Cheap taps can snap off in the hole, turning a five-minute job into a two-hour nightmare, but Walter taps are built to last.

This 1/2"-13 National Coarse (NC) tap features a plug chamfer, which is the standard style for most applications. It has a slight taper at the beginning to help start the thread easily while still being aggressive enough to cut full threads relatively close to the bottom of a hole if needed (though best for through holes). The ground threads cut smoothly through mild steel, aluminum, and even stainless steel, which is notorious for work-hardening and destroying lesser tools.

Don't let a stripped thread slow down your project. Keep a Walter 03B082 in your tool chest for those moments when you need to bolt a bracket, mount a fixture, or repair a piece of equipment. Its superior cutting geometry reduces the force needed to turn the tap, saving your wrists and ensuring a clean, professional finish every time.
