Thread size and pitch

The Cleveland C54813 is a straight flute hand tap designed to cut internal threads of 11/16 inch diameter with an 11 threads per inch UNS pitch. It is intended for machinists and maintenance technicians who need to create new threads or repair damaged ones in a variety of materials.

Taper lead and thread depth

This tap features a taper chamfer that eases entry and alignment when starting a thread by hand. The thread length measures 1.81 inches within an overall tool length of 4.03 inches, which limits the maximum depth of full-form threads that can be cut in a single pass.

Material capacity and fit class

Constructed from high speed steel with a bright uncoated finish, the tap handles general-purpose ferrous and non-ferrous metals. It is manufactured to a H3 thread limit for a class 2B fit, providing standard tolerance for general assemblies but not the tighter control required for precision or high-stress joints.

Questions about this item

Should I choose the 11/16"-11 UNS tap or a different thread size for my application?

Select the 11/16"-11 UNS tap only when the drawing or part specifies that exact diameter and 11 threads per inch; other sizes will not produce the correct thread form.

What does the 4.03 in overall length mean when I am tapping a hole?

The 4.03 in overall length determines how deep the tap can reach into a blind hole and whether it clears fixtures or work-holding on your machine.

How does the straight-flute design affect chip removal in a 1.81 in thread length?

Straight flutes push chips ahead of the tap, so for a 1.81 in thread depth you must reverse frequently or use a through-hole setup to avoid packing.
