Cleveland C54273 Hand Tap 8-32 Unc Plug 2-flute Hss

Product Description

The CLEVELAND C54273 is a straight-flute hand tap designed for cutting 8-32 UNC internal threads in both blind holes and through-holes. Manufactured from high speed steel (HSS) with a bright, uncoated finish, it delivers sharp cutting performance across a broad range of workpiece materials. The plug chamfer style — 3 to 5 threads of lead — makes it the standard choice for most general tapping work where a thread starter tap has already been used or where full thread depth from a through-hole is required. Overall length is 2.125 inches, with a thread length of 0.38 inches and a right-hand thread direction. Class of fit is 2B with an H3 thread limit, meeting standard tolerance requirements for most fastener applications.

This tap is suited for use in machine shops, maintenance and repair operations, and production environments where 8-32 threaded holes are required. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. The 2-flute straight-flute geometry is well matched to through-hole threading and shorter blind holes where chip evacuation is managed manually or with cutting fluid. It is part of the Cleveland Series 1002 and is sold individually.

Key Features

• Bright uncoated finish — inspect and resharpen easily
• 2-flute straight-flute design for controlled chip formation
• Compact 2.125-inch OAL suits standard tap handles and tapping heads

Compatibility

Designed as a standard replacement or service tap for 8-32 UNC threaded hole applications in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces. Part of Cleveland Series 1002.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench or tapping head sized for the 0.168-inch shank diameter. Always apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Back the tap out periodically to break chips when working blind holes. Never exceed the torque capacity of the tap — 8-32 taps are small-diameter and susceptible to breakage if torque is applied unevenly or if the hole is undersized.
