Three-Piece Tap Kit for #5-40 Threads

This Cleveland C54191 kit supplies taper, plug and bottoming taps for cutting #5-40 UNC threads. The three-piece set covers the full threading sequence from start to finish in a single package. It is aimed at mechanics and hobbyists who need to create internal threads in metal workpieces.

High-Speed Steel Holds Up in Extended Use

High-speed steel construction resists heat buildup during prolonged tapping operations. The uncoated bright finish allows cutting fluid to cling directly to the flutes for consistent lubrication. Three flutes on each tap provide steady chip evacuation so the tool stays free-cutting through deep holes.

Right-Hand Threads with Standard Fit

Thread limit H2 and class of fit 2B produce standard right-hand threads compatible with common #5-40 fasteners. The 75 percent thread drill size #39 guides accurate hole preparation before tapping. Overall length of 1 15/16 inches and thread length of 5/8 inch suit typical hand-tapping reach requirements.

Questions about this item

How much heat or noise does the #5-40 tap generate during extended use?

As a hand-operated cutting tool, the Cleveland C54191 produces no motor noise, vibration, or heat buildup regardless of how long the threading session lasts.

What drill bit must I already own to prepare the hole for this #5-40 UNC tap?

A #39 drill bit is required to create the 75 percent thread engagement hole before starting the taper, plug, or bottoming tap.

Will the H2 thread limit and 2B class of fit work with older #5-40 bolts I have on hand?

Yes, the H2 limit and 2B fit are standard for UNC #5-40 threads, so the taps will cut internal threads that accept existing #5-40 external threads.
