Cleveland C54653 Straight Flute Hand Tap
The Cleveland C54653 is a straight flute hand tap designed for creating internal threads in a variety of materials. It features a 7/16"-14 UNC thread size with a plug chamfer for general-purpose threading tasks. Made from high-speed steel with a bright uncoated finish, it offers durability for maintenance and repair work. Right-hand threading ensures compatibility with standard fasteners.
Suitable for machinists and maintenance technicians
This tap suits professionals cutting new threads or repairing damaged ones in through-holes and blind holes where a plug chamfer is appropriate. The H3 thread limit and 2B class of fit meet standard industrial requirements for general applications. Buyers needing a bottoming or taper chamfer for specific hole depths should look at alternative tap styles. Those requiring coated tools for high-volume production or difficult alloys will need a different surface treatment.
7/16"-14 UNC thread size with H3 limit
The defining specification is the 7/16"-14 UNC thread size combined with an H3 thread limit and 2B class of fit. This determines the exact pitch diameter tolerance and ensures the finished thread matches standard Unified National Coarse requirements. The 1.44-inch thread length and 3.16-inch overall length provide adequate reach for typical hand-tapping operations. A 75 percent thread drill size U is specified for preparing the correct hole before tapping.

Questions about this item
Does the Cleveland C54653 tap come with a handle or drill bit, or must they be bought separately?
The tap is a straight-flute hand tap only; a tap wrench or handle and the correct size-U drill bit are sold separately.
How do I choose between the H3 limit and other thread limits for a 7/16"-14 UNC hole?
H3 is the standard limit for a 2B class of fit; select it for general-purpose threading unless a tighter or looser tolerance is specified.
What does the 1.44-inch thread length mean when tapping a blind hole in steel?
It indicates the maximum full-thread depth the tap can cut in one pass; ensure the drilled hole is deeper than 1.44 inches to avoid bottoming out.
