Cleveland C54924 Hand Tap — Thread Cutting Tool
The Cleveland C54924 is a straight-flute hand tap designed to cut internal UNC threads in a 1 inch minus 8 pitch size. It suits maintenance technicians and machinists who need to create or repair threaded holes in steel, cast iron and similar materials using hand or light machine operations.
Plug Chamfer Limits Starting Ease
A plug chamfer engages the workpiece with moderate lead threads, making it practical for through holes and blind holes with adequate clearance. The 75 percent thread drill size of 22.25 mm defines the maximum hole diameter before thread depth drops below specification, so holes drilled larger than this will not yield full thread engagement.
High-Speed Steel Construction and Bright Finish
The tap is made from high-speed steel with a bright uncoated finish and a right-hand cutting direction. Its overall length of 5.13 inches and 2.5 inch thread length provide reach for deeper holes, while the H4 thread limit and 2B class of fit ensure standard tolerance for general-purpose assembly work.

Questions about this item
Which thread size and tap style should I select for a 1"-8 UNC hole?
This tap is a 1"-8 UNC straight-flute hand tap with a plug chamfer, suited for through or blind holes in general-purpose threading.
What does the 2.5 inch thread length mean when I am tapping a workpiece?
The 2.5 inch thread length is the cutting portion of the tap; it determines the maximum depth of full-form threads you can produce in a single pass.
How does the H4 thread limit and 2B class of fit affect the finished thread?
H4 is the pitch-diameter limit for this tap, and 2B is the standard internal-thread fit class; together they define the tolerance zone for the finished 1"-8 UNC thread.
