Cleveland #6-40 UNF Hand Tap Set
This three-piece Cleveland tap set cuts #6-40 UNF threads in right-hand direction. The set includes taper, plug and bottoming straight-flute taps made from high-speed steel with a bright uncoated finish. Each tap measures two inches overall with an eleven-sixteenths inch thread length. Three flutes provide chip clearance during hand threading operations.
Suitable for internal threading in through
Mechanics and hobbyists cutting #6-40 UNF threads in metal will find the three tap styles cover the full threading process. The H2 thread limit produces a class 2B fit for standard applications. Builders needing left-hand threads, different thread standards or larger diameters must select alternative tooling. Coated taps for extended wear in abrasive materials are not included in this set.
Thread size #6-40 UNF determines compatibility
The #6-40 UNF designation specifies a number six diameter with forty threads per inch in the Unified National Fine series. A number thirty-three drill at seventy-five percent thread engagement prepares the correct hole size. Verify the workpiece requires this exact thread specification before purchase.

Questions about this item
Should I pick the taper, plug or bottoming tap first for a #6-40 UNF hole?
Start with the taper tap to begin the thread, follow with the plug tap to deepen it, and finish with the bottoming tap to reach the bottom of a blind hole.
What does the 11/16 in thread length mean when I am tapping a part?
The cutting portion of each tap is 11/16 in long, so the full thread depth you can produce in one pass is limited to that length.
How does the H2 thread limit affect the fit of a #6-40 UNF thread?
The H2 limit sets the pitch-diameter tolerance for a class 2B fit, giving a standard medium fit for general-purpose UNF fastening.
