OVERVIEW

Reliable Threading Solutions for Fabrication and Repair

In the world of welding and metal fabrication, having the right cutting tools is just as important as having the right welder. The Walter 5-40 NC Plug HSS Tap (03A052) is an essential addition to any fabricator's toolkit, offering the reliability needed for creating secure fastening points in metal projects. When threads are stripped or new holes need to be tapped in custom brackets, frames, or machinery, this high-speed steel tap provides the bite and durability required to get the job done right.

Walter Surface Technologies is known for producing heavy-duty industrial consumables, and their line of taps is no exception. This 5-40 NC tap is built to cut through tough materials that welders encounter daily, such as stainless steel and mild steel, as well as softer metals like aluminum. The "Plug" style design is particularly effective for through-holes, allowing the chips to clear effectively while establishing a strong, full-depth thread. Its ground thread construction ensures that every bolt or screw fits perfectly, eliminating the frustration of cross-threading or loose fits.

Durability is key in a shop environment. The hardened and tempered HSS body of this tap resists dulling and breakage, providing a long service life even under rigorous use. Whether you are tapping holes in a newly welded assembly or performing maintenance on shop equipment, this tool offers the performance you can count on. Don't let a broken or dull tap slow down your production; equip your shop with Walter's high-performance threading tools and ensure your connections are as strong as your welds.

FAQ

A plug tap typically has 3-5 tapered threads at the tip, making it ideal for through holes or threading close to the bottom of a blind hole. A taper tap has a longer lead (7-10 threads) and is easier to start but requires more depth to cut full threads.

This tap is made of High-Speed Steel (HSS), which offers superior hardness and heat resistance compared to carbon steel taps.

Yes, the Walter 5-40 NC HSS tap is designed to cut stainless steel, as well as mild steel and aluminum.

For a 5-40 NC thread, the standard tap drill size is a #38 drill bit.

Plug taps can be used for blind holes, but they will not create full threads all the way to the very bottom. For threading to the bottom of a blind hole, a bottoming tap is usually required after starting with a plug tap.

No, this is the tap bit only. You will need a tap wrench or T-handle to operate it manually, or a suitable holder for machine use.

NC stands for National Coarse, which indicates the thread pitch standard. 5-40 means a #5 diameter with 40 threads per inch.
