Drill America 1/4"-18 HSS Plug Hand Tap

This Drill America HSS plug hand tap cuts internal threads in a 1/4"-18 size. It suits maintenance technicians and machinists who need to create or repair threads in through holes. The high-speed steel construction handles general-purpose tapping across common materials. It is not intended for bottoming threads in blind holes where a bottoming tap is required.

1/4"-18 thread capacity and material range

The tap produces a 1/4"-18 thread form with a 0.25 decimal equivalent for the major diameter. It works reliably in through-hole applications on steel, aluminium and similar metals. The plug chamfer starts the thread squarely but does not cut to the bottom of a blind hole. Users needing full-depth threads in closed holes must select a different tap style.

California Proposition 65 notices included

The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm. These notices inform safe-handling practices such as wearing gloves and avoiding dust inhalation. No additional accessories, lubricants or software are bundled with the tap.

Questions about this item

Will the 1/4"-18 thread pitch match my existing NPT pipe fittings?

The 1/4"-18 size corresponds to the standard NPT thread pitch used on 1/4 inch nominal pipe, so it will cut threads compatible with those fittings.

How do I verify the plug tap is cutting threads correctly in a through-hole?

The plug chamfer starts threads squarely; after tapping, the fitting should thread in smoothly for several turns before resistance increases at the taper engagement.

Does the package include a tap wrench or drill bit for the 0.25 inch tap drill size?

The box contains only the HSS plug hand tap; a suitable tap wrench and the correct drill bit for the tap drill size must be purchased separately.
