Cleveland C54267 Hand Tap 8-32 Unc Plug 3-flute Hss

Product Description

The CLEVELAND C54267 is a straight-flute hand tap designed for cutting internal 8-32 UNC threads in a wide range of metallic workpieces. Built from high speed steel (HSS) with a bright, uncoated finish, it is ground to a Class 3B fit and an H2 thread limit, providing the dimensional precision required for close-tolerance threaded assemblies. The plug chamfer (3-5 threads) allows easy thread starting in both through-holes and blind holes. With three straight flutes, the tap suits general-purpose hand tapping and low-speed machine tapping operations where chip flow is manageable. Overall length is 2.125 inches with a thread length of 0.38 inches (19.05 mm).

This tap is suited for job shop, maintenance, and production environments where 8-32 threads are needed in alloy steel, carbon steel, aluminum, and free-machining stainless steel. It is equally functional for through-hole and blind-hole applications, making it a practical all-around choice for machinists, tool-and-die technicians, and maintenance tradespeople working on light fastener assemblies, instrument enclosures, and general fabrication work. The straight-flute geometry keeps the tool straightforward to sharpen and resharpen in the field.

Key Features

• 8-32 UNC thread form, Class 3B fit, H2 thread limit for precise tolerance control
• Plug chamfer (3-5 thread lead) starts easily in through-holes and most blind-hole applications
• High speed steel construction provides good wear resistance across steel, aluminum, and free-machining stainless
• Bright, uncoated finish allows visual wear monitoring and suits most cutting-fluid environments
• Three straight flutes support hand tapping and low-speed machine tapping
• Right-hand thread direction; standard tapping wrenches and T-handles fit the 0.25-inch square drive

Compatibility

Designed for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring 8-32 UNC internal threads. Suitable for both blind-hole and through-hole threading applications per Cleveland Series 1002.

Installation Notes

Secure the workpiece fully before tapping and apply a suitable cutting fluid for the material being threaded. Use a properly aligned tapping wrench or T-handle to avoid tap breakage from side loading. Back the tap off periodically to break chips, especially in blind-hole applications. High speed steel taps are brittle — do not force the tap if resistance increases unexpectedly.
