Cle-line C62153 Spiral Point Tap 6-32 Unc 2 Flute Plug Hss

Product Description

The CLE-LINE C62153 is a spiral point plug tap designed for through-hole threading operations in steel, cast iron, and non-ferrous metals. It is manufactured from high speed steel (HSS) with a bright uncoated finish and carries an H3 thread limit for consistent tolerance control. The tap cuts a 6-32 UNC right-hand thread using 2 flutes and a plug chamfer, which requires a pre-drilled through hole for proper chip ejection. Overall length is 2.0 inches with a thread length of 0.6875 inches. Machinists and maintenance technicians install this tap by hand or in a tapping machine for small-fastener thread creation in light industrial and precision assembly applications.

The C62153 is suited for through-hole threading in production and maintenance environments where 6-32 UNC fastener threads are required. Typical applications include threading holes in sheet metal enclosures, electronic chassis, and light structural components made from steel or non-ferrous materials. The plug chamfer style distributes cutting load across several leading threads, making it appropriate for both hand tapping and machine tapping setups where full-depth thread engagement is needed from a clear through hole.

Key Features

• 6-32 UNC thread form with H3 limit for close tolerance control
• Spiral point geometry pushes chips ahead of the tap, keeping the flutes clear during through-hole threading
• Plug chamfer distributes cutting load across the leading threads for smooth entry
• High speed steel construction provides wear resistance in steel and cast iron
• Bright uncoated finish suitable for use with cutting fluids and oils
• Right-hand cut, compatible with standard tapping attachments and T-handles

Compatibility

Designed as a standard replacement or stock tap for through-hole threading operations requiring a 6-32 UNC spiral point plug tap with H3 thread limit in HSS. Compatible with materials including steel, cast iron, and non-ferrous metals as noted in the product specifications.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a tap wrench, tapping handle, or tapping head sized for the shank diameter. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for a 6-32 UNC thread before beginning. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Never force a tap if resistance increases unexpectedly, as breakage in the hole can make extraction difficult.
