Straight Flute Hand Tap 3/4"-16

The Cleveland C54846 is a straight flute hand tap designed to cut internal threads in a 3/4 inch -16 UNF size. It is intended for manual threading operations where a taper lead eases the start of the cut. The high speed steel construction provides durability for general-purpose use in maintenance or repair tasks. This tap suits technicians and hobbyists creating new threads by hand.

Taper Lead and UNF Thread Standard

The taper chamfer requires a longer engagement to reach full thread depth compared to plug or bottoming styles. This makes it less suitable for blind holes where clearance is limited or for threading close to a shoulder. The unified fine thread form demands a precise 75 percent thread drill size of 17.50 mm for a class 2B fit. Users must ensure the workpiece material is compatible with uncoated high speed steel.

High Speed Steel Bright Finish

The bright uncoated surface means no additional lubricity or heat resistance from coatings such as titanium nitride is present. Cutting fluid is essential to prevent galling and to extend tool life during operation. The H3 thread limit controls the pitch diameter tolerance for the class 2B fit specification. Buyers needing coated performance or a different thread limit should select an alternative tap.

Questions about this item

Should I pick the 3/4"-16 Taper tap or a different size for my threading job?

Choose this 3/4"-16 Taper tap when you need to cut UNF threads in a 3/4 inch hole with a 16 threads-per-inch pitch; the taper lead helps start threads straight in through-holes or blind holes.

What does the 4.25 inch overall length mean when the tap is in my wrench?

The 4.25 inch overall length gives enough reach for deeper holes while keeping the tool manageable in a standard tap wrench; the 2 inch thread length limits the maximum full-thread depth you can cut in one pass.

How does the H3 thread limit affect the fit with a 2B class nut?

The H3 limit produces threads that fall within the 2B class of fit, giving a standard free-running assembly with a 75 percent thread engagement when drilled with the 17.50 mm tap drill.
