Cleveland C54523 Straight Flute Hand Tap

The Cleveland C54523 is a three-piece straight flute hand tap set designed for creating UNF threads. It suits mechanics and technicians who need to cut precise internal threads in metal workpieces using hand tools. The high-speed steel construction provides durability for general-purpose threading tasks in maintenance and repair environments.

Verify thread specification and drill size

Confirm the required thread size is 5/16"-24 UNF with a Class 3B fit before ordering. Ensure the workpiece material is compatible with high-speed steel cutting tools and uncoated bright finish. Check that a 75 percent thread drill size I is available for the pilot hole preparation.

Fits manual threading operations

The tap requires a suitable tap wrench for hand operation and cutting fluid for effective chip evacuation. It frees the user from needing powered threading equipment for small batch or field repair work. The four-flute design helps maintain alignment during manual thread cutting in through or blind holes.

Questions about this item

Does the Cleveland C54523 kit include the 75 percent thread drill size I bit or must it be purchased separately?

The kit contains three straight-flute hand taps sized 5/16"-24 UNF with H3 limits and 3B class of fit; the 75 percent thread drill size I bit is not included and must be bought separately.

How do the three taps in the Cleveland C54523 kit differ from one another?

All three taps share the same 5/16"-24 UNF size, high-speed steel construction, bright finish, four flutes, 1 1/8 in thread length and 2 23/32 in overall length; they are supplied as a matched set rather than as taper, plug and bottoming variants.

What does the 5/16"-24 UNF 3B designation mean when I use these taps in a workpiece?

It means each tap cuts a unified fine thread with 24 threads per inch to a 3B class of fit, producing a right-hand internal thread 1 1/8 in deep that meets H3 pitch-diameter limits for close-tolerance assemblies.
