Cleveland C55222 Hand Tap Purpose
The Cleveland C55222 is a straight flute hand tap designed to cut internal threads in pre-drilled holes. It suits maintenance technicians and machinists who need to create or repair UNF threads using hand tools or a tapping head.
Users and Limitations
This tap fits buyers who require a 5/16"-24 UNF thread form with a bottoming chamfer for threading to the bottom of blind holes. It is not for buyers who need a taper or plug chamfer for easier starting in through-holes. It is also not for operators who require a spiral flute design to evacuate chips from deep holes in ductile materials.
Critical Specification
The thread limit is H3 and the class of fit is 2B, which together determine the allowance and tolerance of the finished thread. Selecting a different limit or class will change the fit between the internal thread and the mating external part.

Questions about this item
What comes in the box with the Cleveland C55222 tap and what else is needed?
The box contains the straight-flute hand tap only; a 75-per-cent thread drill size I and a suitable tap wrench must be purchased separately.
How do I choose the right version of this tap for my job?
This model is a single specification: 5/16"-24 UNF, bottoming, H3 limit, 2B class of fit, TiN-coated high-speed steel; select it when those exact thread parameters are required.
What does the 5/16"-24 UNF designation mean when I use the tap in a real workpiece?
It cuts a unified fine thread with a 5/16-inch major diameter and 24 threads per inch, producing a class 2B fit in a hole drilled to size I.
