Cleveland C55162 Hand Tap 5-40 Unc Plug 3-flute Tin Hss

Product Description

The CLEVELAND C55162 is a 5-40 UNC straight-flute hand tap designed for cutting internal threads in metalworking applications. Built from high speed steel with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction during threading operations. It features a plug chamfer for general-purpose use in both blind and through-hole applications. The 3-flute geometry and right-hand thread direction make it a standard production choice for machinists and maintenance technicians working with fine-pitch unified threads. The H2 thread limit holds a 2B class of fit, suitable for most standard fastener thread tolerances.

This tap is suited for threading operations in ferrous and hard materials including steel, cast iron, and stainless steel. The 5-40 thread size is commonly used in small fastener and instrument work. With a thread length of 0.31 inches and an overall length of 1.938 inches, this tap fits standard tap wrenches used in bench work and light production environments. It is appropriate for job shop, maintenance, and light manufacturing settings where consistent thread quality in small-diameter holes is required.

Key Features

• TiN coating extends tool life and reduces built-up edge in steel and stainless steel
• Plug chamfer allows starting in through-holes or partially blind holes
• 3-flute straight-flute design provides chip clearance in short-chipping materials
• H2 thread limit produces 2B class of fit for standard unified thread tolerance
• Right-hand thread direction for standard tap wrench operation
• High speed steel construction handles a range of ferrous material applications

Compatibility

Designed for blind hole and through-hole threading in cast iron, stainless steel, and steel. Fits standard tap wrenches sized for small-diameter taps with a 0.141-inch shank diameter.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap wrench or tapping fixture. Ensure the workpiece is securely clamped and the tap is started perpendicular to the hole to avoid thread damage or tap breakage. Apply appropriate cutting fluid for the material being tapped. Back the tap off periodically during cutting to break chips and prevent binding, particularly in blind holes.
