Cleveland C54349 Hand Tap 10-32 Unf Plug 4-flute Hss

Product Description

The CLEVELAND C54349 is a 10-32 UNF straight-flute hand tap designed for threading operations in both blind holes and through-holes. Built from high speed steel (HSS) with a bright, uncoated finish, this plug-chamfer tap cuts right-hand threads to a 3B class of fit at an H2 thread limit. With 4 flutes and 32 threads per inch, it delivers consistent thread form across a range of workpiece materials. The overall length is 2.375 inches, and the thread length is 0.5 inches. At 0.06 pounds, it is a lightweight, precision hand tool suited for machine shops, maintenance facilities, and fabrication environments.

This tap is designed for threading 10-32 UNF fastener holes in applications where a plug chamfer entry is appropriate. The plug chamfer provides a balance between starting ease and thread engagement, making it suitable for both blind hole and through-hole work. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. It fits into a standard tap wrench and works in scenarios where manual thread cutting is required for repair, production, or prototype work.

Installation Notes

This hand tap is installed and driven using a tap wrench by a machinist, toolmaker, or maintenance technician. Always secure the workpiece and ensure the hole is properly drilled and chamfered to the correct tap drill size before beginning. Apply cutting fluid appropriate to the workpiece material to reduce friction and extend tool life. Back off the tap periodically to break chips, particularly when working in blind holes.
