Value Collection MSC-04422580 Straight Flute Tap 2-56 Unc

Product Description

The VALUE COLLECTION MSC-04422580 is a straight flute tap designed for cutting internal threads in a 2-56 UNC thread form. Made from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in standard threading applications. It features a taper chamfer for gradual thread engagement and a 3-flute geometry that provides chip clearance during the threading operation. With an overall length of 1.75 inches and a thread length of 0.4375 inches, it is sized for small-diameter work typical in precision assemblies. The right-hand thread direction and 2B class of fit make it compatible with standard fastener tolerances. Licensed machinists and tool-and-die technicians are the primary users.

This tap is suited for threading small-diameter holes in ferrous and non-ferrous metals, plastics, and similar materials. The taper chamfer style makes it well suited for through-hole applications where the tap can advance progressively through the material. It is commonly used in precision manufacturing, electronics enclosure fabrication, instrument assembly, and general machine shop work where 2-56 UNC threaded fasteners are specified. The H2 thread limit provides a standard tolerance range appropriate for most commercial and industrial threaded connections at this size.

Key Features

• 2-56 UNC thread form with right-hand direction for standard fastener compatibility
• High-speed steel construction provides wear resistance across a range of workpiece materials
• Taper chamfer distributes cutting load gradually, reducing tap breakage risk in through-hole applications
• 3-flute geometry supports chip evacuation during threading
• H2 thread limit and 2B class of fit meet standard commercial tolerance requirements
• Bright, uncoated finish suitable for general-purpose use without specialized coolant requirements

Compatibility

Designed as a general-purpose straight flute tap for 2-56 UNC threaded holes in standard through-hole machining applications.

Installation Notes

Use in a tapping fixture, drill press, or machine tool to maintain axial alignment and prevent tap breakage in small-diameter work. Power down and secure the workpiece fully before beginning the threading operation. Apply a suitable cutting fluid for the workpiece material to extend tap life and improve thread finish. Discard the tap if cutting edges show wear or chipping, as a damaged tap increases the risk of breakage and thread damage in the workpiece.
