Cleveland C55130 Straight Flute Hand Tap

The Cleveland C55130 is a straight flute hand tap designed for creating internal threads in a variety of materials. It suits machinists and maintenance technicians who need reliable thread cutting for repair or small-batch production work. The H3 thread limit provides a standard fit for general-purpose applications.

Practical limits of UNF 7/16"-20 plug tap

This tap cuts a Unified National Fine thread with a 7/16 inch diameter and 20 threads per inch. The plug chamfer offers a moderate lead for starting threads in through holes or blind holes with adequate depth. The 75 percent thread drill size of 9.95 mm must be observed to achieve the correct Class of Fit 2B engagement.

High-speed steel construction with TiN coating

The tap is manufactured from high-speed steel and features a titanium nitride coating that enhances wear resistance and extends tool life. Right-hand cutting direction matches conventional threading operations. An overall length of 3.16 inches with a 1.44 inch thread length provides sufficient reach for typical hand-tapping tasks.

Questions about this item

Should I choose the 7/16"-20 UNF tap or a different thread size?

Choose the 7/16"-20 UNF tap when you need to cut fine-thread holes of that exact diameter and pitch; other sizes will not match the required fastener.

What does the 1.44 in thread length mean when I use the tap in a real machine?

The 1.44 in thread length is the cutting portion that forms full threads; it determines the maximum depth of usable threads in a single pass.

How does the H3 thread limit affect the class of fit in practice?

The H3 limit produces a 2B class of fit, giving standard tolerance for general-purpose assemblies with the 7/16"-20 UNF thread.
