Cle-Line #2-64 UNF Hand Tap
This straight-flute hand tap cuts #2-64 UNF threads with a taper lead for easy starting. It is made from high-speed steel with a bright finish and suits general-purpose threading in maintenance or small-batch work.
Consistent cutting under sustained load
Three flutes distribute chip load evenly during continuous hand or powered tapping. The 1.75 in overall length and .44 in thread length provide stable engagement so the tap resists wandering through deeper holes.
Verify drill size and fit class before ordering
A 1.80 mm drill produces the recommended 75 percent thread depth for this H2 limit tap. The 2B class of fit matches standard Unified fine threads; tighter or looser fits will require a different limit.

Questions about this item
How much heat does the #2-64 UNF tap generate during extended use?
The high-speed steel construction dissipates heat well during normal hand-tapping operations, but continuous power tapping may require cutting fluid to manage temperature.
What drill size do I need before using this #2-64 tap?
A 1.80 mm drill creates the 75 percent thread depth recommended for the #2-64 UNF thread form.
Will this H2 limit tap fit older 2B class threaded holes?
Yes, the H2 thread limit is designed for standard 2B class of fit, matching legacy UNF specifications.
