Value Collection MSC-04422598 Tap Set 2-56 Unc

Product Description

The VALUE COLLECTION MSC-04422598 is a 3-piece tap set ground to cut 2-56 UNC threads in a right-hand direction. Made from high-speed steel with a bright, uncoated finish, this set is suited for threading small-diameter holes in metal workpieces where precision and thread form accuracy matter. The set covers the full tap sequence for 2-56 UNC work, with an overall length of 1.75 inches and a thread length of 0.4375 inches. Each tap features 3 flutes to support chip evacuation during the threading operation. An H2 thread limit designation indicates the tolerance class ground into the tap, which is relevant when selecting taps for close-tolerance threaded fastener applications.

This tap set is intended for use in machine shops, maintenance environments, and production settings where 2-56 UNC threaded holes are required. The 2-56 thread size is common in small instrumentation, electronics hardware, and precision mechanical assemblies. The 3-flute geometry works well in a range of materials including mild steel, aluminum, and similar machinable metals. The set is packaged as a single unit and is suitable for use with a standard tap handle or tapping attachment on a drill press or milling machine.

Key Features

• 2-56 UNC thread form, right-hand direction
• High-speed steel construction for durability across a range of machinable metals
• 3-flute design supports chip clearance during tapping
• H2 thread limit for close-tolerance thread production
• Bright, uncoated finish — no coating to affect thread geometry
• 3-piece set covers the full tap sequence for this thread size

Compatibility

Designed for cutting 2-56 UNC threads in standard machinable materials; compatible with manual tap handles and powered tapping attachments sized for small-diameter taps.

Installation Notes

Tapping operations should be performed by a machinist or qualified technician familiar with thread-cutting procedures. Always ensure the workpiece is securely fixtured and the tap is properly aligned before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Do not force a tap through a hole that is undersized — verify the correct tap drill diameter for 2-56 UNC before drilling.
