Cleveland C54264 Hand Tap 8-32 Unc Plug 2-flute Hss

Product Description

The CLEVELAND C54264 is a straight-flute hand tap designed for cutting 8-32 UNC internal threads in both blind holes and through-holes. Ground from high speed steel with a bright, uncoated finish, it delivers consistent thread form across a wide range of workpiece materials. The plug chamfer — typically 3 to 5 lead threads — allows the tap to start easily in a pre-drilled hole and is the go-to choice for most general tapping work. With a 3B class of fit and an H2 thread limit, this tap produces threads suited to standard tolerance applications where reliable fastener engagement is required. It is sized for use with a standard tap wrench or tapping fixture.

This tap is suited to production and maintenance machining environments where 8-32 UNC threads are common. It performs in blind-hole and through-hole applications on alloy steel, carbon steel, aluminum, and free-machining stainless steel. Machinists, tool-and-die makers, and maintenance technicians reach for this style of tap when hand-tapping or running low-speed machine tapping operations on ferrous and non-ferrous workpieces.

Key Features

• 8-32 UNC thread form with plug chamfer for general-purpose hand tapping
• High speed steel construction for durability across steel, aluminum, and stainless applications
• Bright, uncoated finish — no coating buildup to affect thread tolerance
• 3B class of fit with H2 thread limit for standard tolerance threads
• 2-flute straight flute design for chip clearance in both blind and through-hole work
• Right-hand thread direction, compatible with standard tap wrenches and tapping fixtures

Compatibility

Designed for cutting 8-32 UNC threads in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces in blind-hole and through-hole configurations.

Installation Notes

A licensed machinist or qualified maintenance technician should select the correct tap drill size for 8-32 UNC threads before beginning. Secure the workpiece fully before tapping and apply a cutting fluid appropriate to the workpiece material. For hand tapping, use a properly fitting tap wrench and back off the tap periodically to break chips, especially in blind holes. Inspect the tap for wear or chipping before each use — a damaged tap can seize in the hole or produce out-of-tolerance threads.
