Value Collection MSC-04422564 Straight Flute Tap 2-56 Unc

Product Description

The VALUE COLLECTION MSC-04422564 is a straight flute tap designed for cutting internal threads in through-holes and shallow blind holes. Manufactured from high-speed steel with a bright uncoated finish, it cuts a 2-56 UNC right-hand thread and is ground to a 2B class of fit with an H2 thread limit. The plug chamfer, with its moderate lead-in, makes it well suited for through-hole tapping where the tap can pass fully through the workpiece. With a thread length of 0.4375 inches and an overall length of 1.75 inches, this tap is sized for small-diameter precision work. Machinists, tool-and-die makers, and maintenance technicians install it in hand-tapping handles or machine-tapping setups.

This tap is used in general-purpose metalworking and maintenance applications where a 2-56 UNC thread is required. Typical use cases include tapping holes in thin sheet metal, small instrument enclosures, electronic hardware, and precision mechanical assemblies. The straight flute geometry is appropriate for short-chipping materials such as brass, aluminum, and mild steel. It is sold individually and is appropriate for both low-volume hand tapping and light-duty machine tapping operations in job shop, maintenance, and assembly environments.

Compatibility

Designed as a standard replacement or stock tap for any application requiring a 2-56 UNC plug chamfer straight flute tap in H2 ground limits and 2B class of fit.

Installation Notes

Install in a properly sized tap wrench or machine tap holder rated for the shank diameter before use. Always drill the correct tap drill size for a 2-56 UNC thread prior to tapping, and apply a suitable cutting fluid to extend tool life and improve thread quality. Power down or disengage the spindle before changing or inspecting the tap in a machine setup. Back off the tap periodically to break chips and prevent tap breakage in blind-hole applications.
