Cleveland C54215 Hand Tap 6-32 Unc Plug Hss Bright

Product Description

The CLEVELAND C54215 is a 6-32 UNC hand tap designed for cutting internal threads in both blind holes and through-holes. Built from high speed steel with a bright uncoated finish, this plug chamfer tap provides a balance of lead-in ease and thread cutting depth suited to production and maintenance threading work. The straight 2-flute design operates right-hand with a Class 3B fit and H2 thread limit, delivering close-tolerance threads in a range of ferrous and non-ferrous materials. Overall length is 2 inches with a thread length of 0.38 inches. Machinists, tool-and-die technicians, and maintenance mechanics reach for this tap when hand-tapping or machine-tapping 6-32 fastener holes.

The C54215 is suited for threading applications in alloy steel, carbon steel, aluminum, and free-machining stainless steel. Its plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for most general threading jobs, whether starting a fresh hole or continuing after a taper tap. It is used in job shops, maintenance facilities, and production environments where 6-32 UNC threads are common in light structural assemblies and electronic enclosures.

Compatibility

Designed as a direct-fit hand tap for 6-32 UNC threaded holes; compatible with standard tap wrenches and machine tap holders accepting a 0.141-inch round shank with a 3/16-inch square drive end.

Installation Notes

Secure the workpiece before tapping and ensure the correct tap drill size is used for 6-32 UNC threads to achieve proper thread engagement. Apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread finish. Back the tap off a partial turn periodically when hand-tapping to break chips and prevent tap breakage. Replace worn or chipped taps rather than forcing them — tap breakage in a hole is difficult to recover from and can scrap the part.
