#8-56 HSS Plug Hand Tap

This #8-56 HSS plug hand tap is designed for cutting internal threads in through holes. It suits machinists, maintenance technicians and hobbyists who need to create precise #8-56 threads by hand or under power in a variety of materials.

Plug style for through-hole tapping

The plug chamfer leads the tap smoothly into a drilled hole, reducing the risk of cross-threading during initial engagement. Applying steady alignment and suitable cutting lubricant prevents tap breakage and ensures clean thread formation in most metals.

Limited to #8-56 thread form

This tap produces only the specific #8-56 thread size and cannot be used for other diameters or pitches. Users requiring different thread standards or blind-hole threading to full depth will need separate tooling such as bottoming taps or alternative sizes.

Questions about this item

How can I confirm the #8-56 plug tap is cutting threads correctly after setup?

The plug style is designed for through holes; verify that threads run the full depth and accept a matching #8-56 fastener without binding.

What comes in the package and what must I supply separately?

The listing covers a single #8-56 HSS plug hand tap; a tap wrench, cutting fluid and the workpiece are not included.

Should I choose the taper, plug or bottoming version for a through-hole job?

The plug style is generally used for through holes, while taper starts threads square and bottoming cuts to the bottom of blind holes.
