Value Collection MSC-04502647 Spiral Point Tap 2-64 Unf

Product Description

The VALUE COLLECTION MSC-04502647 is a spiral point tap designed for cutting 2-64 UNF internal threads in through-hole applications. Manufactured from high speed steel with a bright uncoated finish, this tap features a plug chamfer and two flutes that push chips forward ahead of the cutting edge, reducing chip clogging in production and maintenance threading operations. The H2 thread limit holds tight tolerances for a Class 2B fit, making it a reliable choice for precision threaded assemblies. At 0.06 pounds, this is a compact, single-piece tap suited for machine or hand tapping of small-diameter fastener holes.

This tap is intended for threading through-holes in materials such as aluminum, mild steel, and plastics where a 2-64 UNF thread form is required. The spiral point design is most effective in through-hole work where chips can be pushed clear rather than backed out. Typical applications include instrument manufacturing, electronics assembly, and light mechanical fabrication where fine-thread fasteners are standard. It is sold individually and is compatible with standard tap holders and machine tapping setups using a No. 2 screw thread minor diameter.

Key Features

• 2-64 UNF thread size for fine-pitch small-diameter threading
• Spiral point (gun tap) geometry pushes chips forward in through-hole applications
• High speed steel construction provides hardness and wear resistance
• H2 thread limit maintains Class 2B fit tolerances
• Plug chamfer with 2 flutes for efficient chip evacuation
• Bright uncoated finish suitable for use with cutting fluids

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring a 2-64 UNF Class 2B internal thread in a through-hole. Fits standard tap wrenches and machine tap holders sized for No. 2 diameter taps.

Installation Notes

This tap should be installed by a machinist or maintenance technician familiar with thread-cutting operations. Use the correct drill size for a 2-64 UNF minor diameter before tapping, and apply a suitable cutting fluid for the workpiece material. Secure the tap in a properly aligned tap holder to avoid thread angle errors or tap breakage. Back the tap out periodically when hand tapping to break chips if material conditions require it.
