Walter 5/8-18 NF HSS Plug Tap for Steel and Stainless

Reliable Threading for Fabrication and Repair

When you are in the middle of a fabrication job or fixing a stripped thread on a critical piece of equipment, you need a tap that won't snap or dull instantly. The Walter 5/8-18 NF Plug Tap (03B105) is built for the welder and fabricator who needs reliable tools in their arsenal. Made from tough High Speed Steel (HSS), this tap cuts clean, fine threads into everything from aluminum brackets to heavy stainless steel plates.

The 5/8-18 NF (National Fine) size is perfect for applications requiring fine adjustments or greater strength due to the larger stress area of fine threads. This plug style tap features a standard chamfer that helps align the tap as it starts the hole, making it easier to get straight threads by hand. It is aggressive enough to cut efficiently but gradual enough to distribute the cutting load, reducing the chance of breakage—a common headache with inferior taps.

Whether you are tapping new holes in a custom frame or chasing damaged threads on a repair job, this Walter tap stands up to the abuse. Its ground threads ensure that the bolts you install later will fit smoothly without binding. The HSS material resists the heat generated during cutting, meaning you can work faster without ruining the temper of the tool. It is an essential component for any shop dealing with custom metalwork or machinery maintenance.

Don't settle for cheap carbon taps that wear out after a few holes. Upgrade to Walter's HSS taps for professional results. Pair this tap with a quality cutting fluid like Walter Coolcut to maximize its lifespan and ensure the smoothest possible threads. Keep your projects moving and your connections secure with high-performance threading tools designed for the trade.
