Drill America 7/16"-12 HSS Plug Tap

This Drill America HSS plug hand tap cuts internal threads in a 7/16"-12 size. It is designed for general machine tapping or CNC operations across a wide range of materials. The tool suits professionals and hobbyists creating new threads or repairing damaged ones in through-hole applications.

Verify hole size and material compatibility

Before ordering, confirm the workpiece material is suitable for high-speed steel tooling. Ensure the drilled hole matches the required tap drill size for a 7/16"-12 thread to achieve proper thread engagement. The plug style is intended for through holes; it is not designed for threading to the bottom of a blind hole.

Replaces worn or missing 7/16"-12 taps

This tap replaces a dull, chipped, or lost 7/16"-12 plug tap to restore thread-cutting accuracy. The upgrade is worth it when an existing tool no longer produces clean threads or when a specific 7/16"-12 size is required for a new repair job. It does not suit blind-hole work requiring a bottoming chamfer.

Highlights

  • HSS construction resists wear during threading
  • Plug style suited for through-hole applications
  • 7/16"-12 size matches specific thread requirements
  • Taper start aligns threads square with workpiece

Questions about this item

What comes in the box with the Drill America 7/16"-12 HSS Plug Hand Tap and do I need to buy a tap handle separately?

The package contains the single HSS plug tap. A tap handle or wrench is not included and must be purchased separately to turn the tool.

Should I choose the plug style or a different style for a through hole in steel?

The plug style is designed for through holes. Choose a taper style to start threads square or a bottom style only when threads must reach the bottom of a blind hole.

What does the 4375 decimal equivalent mean when I use this tap in a drill press?

The 4375 figure is the decimal inch size of the 7/16"-12 tap. Drill a 0.4375 inch hole before tapping to produce the correct thread depth.
