OVERVIEW

Reliable Taps for Fabrication and Repair

When you are in the middle of a fabrication job or repairing critical equipment, a stripped thread or a missing bolt hole can bring everything to a halt. The Walter 7/16-20 NF Taper Tap is built to get you back to work fast. Known for their industrial-grade toughness, Walter tools are a favorite among welders and fabricators who need equipment that doesn't quit. This tap is made from heavy-duty High-Speed Steel, meaning it bites into metal and stays sharp long after cheaper carbon taps have dulled or snapped.

The "Taper" style of this tap is your best friend when you are starting a fresh hole. Because the first several threads are ground down at an angle, the tap centers itself easily in the drilled hole. This makes it much easier to get the tap started straight by hand without fighting it. It is perfect for cutting National Fine (NF) threads into brackets, plates, and machinery parts. Whether you are working with mild steel, aluminum, or even harder stainless steel, this tool cuts smoothly and leaves a clean, usable thread every time.

Don't let a broken bolt or a stripped hole slow down your production. The Walter 03B074 is designed to handle the heat and stress of professional metalworking. Its precision ground flutes help clear chips out of the way, preventing binding and breakage. Add this essential threading tool to your shop's inventory and ensure you have the right solution for creating strong, precise 7/16-20 threads whenever the job demands it.
