Cleveland C54092 Straight Flute Hand Tap #2-56 3-piece pneumatic accessory

Cleveland #2-56 Three-Piece Tap Kit

This Cleveland C54092 kit supplies three straight-flute hand taps for cutting #2-56 UNC threads in a workshop or maintenance setting. Machinists and technicians use the set to create internal threads in metal components. The high-speed steel construction suits general-purpose tapping tasks. Each tap serves a distinct stage in the threading process.

High-Speed Steel Build With Bright Finish

The taps are made from high-speed steel with an uncoated bright finish that resists galling during hand operation. Three flutes on each tap provide chip clearance and cutting stability in through or blind holes. A 7/16 inch thread length and 1 3/4 inch overall length fit standard tap handles and wrenches. Right-hand thread direction matches common fastener conventions.

H2 Thread Limit For 2B Class Of Fit

The H2 thread limit produces a 2B class of fit for #2-56 UNC threads, which determines whether the finished thread meets the required tolerance. A 75 percent thread drill size of 1.73 mm is needed before tapping. This kit will not suit metric thread requirements or larger imperial sizes. Builders needing different pitch diameters must select another limit.
