Value Collection JY4945440 5-44 Unf Straight Flute Tap

Product Description

The VALUE COLLECTION JY4945440 is a straight flute tap designed to cut 5-44 UNF internal threads in a left-hand direction. Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread quality in small-diameter applications. The plug chamfer provides a gradual lead-in, making it well suited for through-hole tapping where chips can exit freely. With 3 flutes and an H2 thread limit, the tap holds tight dimensional tolerances appropriate for 2B class of fit assemblies. Overall length is 1-15/16 inches. The tool weighs approximately 0.0074 pounds. Machinists, maintenance technicians, and tool-and-die professionals are the primary users.

This tap is used in applications requiring left-hand 5-44 UNF threads, which appear in precision assemblies where counter-rotation or anti-loosening thread orientation is specified. Common installation scenarios include small fastener work in instrument panels, optical equipment, and mechanical sub-assemblies. The plug chamfer style makes it appropriate for through-hole work across a range of materials compatible with high-speed steel cutting tools, including mild steel, aluminum, brass, and plastics.

Key Features

• 5-44 UNF left-hand thread form for counter-rotation thread applications
• Plug chamfer for gradual thread engagement in through-hole tapping
• 3-flute design provides chip clearance and stable cutting action in small bores
• H2 thread limit holds 2B class of fit tolerances
• High-speed steel construction for general-purpose cutting across common workpiece materials
• Bright, uncoated finish — no coating buildup to affect thread geometry

Compatibility

Designed as a standard replacement or supplemental tap for any setup requiring 5-44 UNF left-hand internal threads with a 2B class of fit and H2 thread limit.

Installation Notes

Tapping should be performed by a machinist or qualified technician using a properly aligned tap wrench, drill press, or tapping machine. Always drill a correctly sized tap drill hole before starting — using an undersized hole risks tap breakage. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Back the tap out periodically to clear chips, especially in blind holes, even though the plug chamfer is optimized for through-hole work.
