Cleveland C55226 Straight Flute Hand Tap 3/8"-24 UNF

Cleveland C55226 Hand Tap

The Cleveland C55226 is a straight flute hand tap designed for cutting 3/8"-24 UNF threads in a variety of materials. It is intended for machinists, maintenance technicians and hobbyists who need to create or repair internal threads by hand or with a tapping head. The high-speed steel body with TiN coating provides wear resistance and extended tool life during threading operations.

Build integration

The tap has an overall length of 2.94 in and a thread length of 1.25 in, fitting standard tap holders and wrenches for manual use. It requires a 75 percent thread drill size of 8.50 mm to prepare the hole before tapping. The H3 thread limit and Class 2B fit ensure the finished threads meet standard tolerances for general-purpose fastening applications. Right-hand cutting direction matches conventional threading requirements.

Suitability

This tool suits users cutting UNF fine-pitch threads in steel, aluminium or plastic where a bottoming chamfer allows threading close to the bottom of a blind hole. It is not suited for buyers needing a taper or plug chamfer for through-hole work, for those requiring larger or smaller thread diameters, or for automated high-volume production where spiral-point or roll-form taps would be more efficient.
