Value Collection MSC-04502563 Spiral Point Tap 2-56 Unc

Product Description

The VALUE COLLECTION MSC-04502563 is a spiral point tap designed to cut internal threads in through-hole applications. Built from high speed steel (HSS) with a bright, uncoated finish, this tap drives chips forward ahead of the cutting zone, making it well suited for continuous production threading. It is configured as a plug chamfer with a 7/16 inch thread length, and produces a 2-56 UNC thread form to a 2B class of fit. Licensed machinists, tool-and-die makers, maintenance mechanics, and precision fabricators will find this tap appropriate for small-diameter threading work in a wide range of materials.

This tap is used for threading small-diameter through-holes in ferrous and non-ferrous metals, plastics, and similar machinable materials. The 2-56 UNC designation places it in the fine end of the coarse-thread unified inch series, a common size in instrument panels, electronic enclosures, small fixtures, and light mechanical assemblies. It is intended for use in a tap handle, tapping head, or CNC rigid-tapping setup.

Key Features

• 2-56 UNC thread form with 2B class of fit for standard tolerance through-hole threading
• Spiral point geometry pushes chips forward, reducing clogging in through-hole applications
• High speed steel construction provides good wear resistance across common machinable materials
• Bright uncoated finish for straightforward use without coating compatibility concerns
• H2 thread limit for consistent fit within standard 2B tolerances
• Right-hand thread direction, plug chamfer entry for general-purpose starting in pre-drilled holes

Compatibility

Designed as a standard replacement or production spiral point tap for any application requiring a 2-56 UNC internal thread in a through-hole configuration.

Installation Notes

This tap should be installed by a qualified machinist or maintenance mechanic familiar with tapping procedures. Always use the correct tap drill size for a 2-56 UNC thread before tapping, and apply an appropriate cutting fluid for the workpiece material. Secure the workpiece and ensure the tap is started perpendicular to the hole to prevent breakage. If using a tap handle, apply steady, even pressure and back off periodically to break chips.
