Value Collection MSC-04423562 Straight Flute Tap 3-56 Unf

Product Description

The VALUE COLLECTION MSC-04423562 is a straight flute tap designed for cutting 3-56 UNF internal threads in a wide range of materials. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features a plug chamfer for general-purpose through-hole and blind-hole tapping. The 3-flute geometry provides efficient chip clearance during hand or machine tapping operations. With an overall length of 1-13/16 inches and a thread length of 0.5 inches, this tap is sized for small-fastener applications common in precision assemblies, electronics, and light mechanical work. The H2 thread limit ensures a 2B class of fit tolerance for standard threaded fastener engagement.

This tap is suited for threading 3-56 UNF holes in light-duty production and maintenance applications. The right-hand thread direction is standard for conventional fastener installation. Plug chamfer taps are the most common choice when starting a thread in a pre-drilled hole, making this tool appropriate for both through-holes and deeper blind holes where a few lead threads are acceptable. Machinists, tool and die technicians, and maintenance mechanics working with small-frame assemblies will find this tap useful for new thread creation and thread repair work.

Key Features

• 3-56 UNF thread form for fine-pitch small-fastener applications
• High-speed steel construction provides good wear resistance across a range of workpiece materials
• Plug chamfer design suitable for through-holes and blind holes with adequate depth
• H2 thread limit maintains 2B class of fit tolerance for standard fastener compatibility
• Right-hand thread direction for conventional tapping operations
• Bright, uncoated finish with no coolant-through requirement

Compatibility

Designed as a standard straight flute tap for use in any hand tap wrench, T-handle, or machine tapping setup sized for small-diameter taps producing 3-56 UNF right-hand threads.

Installation Notes

Install and remove taps using properly sized tap wrenches or machine tap holders to avoid breakage on small-diameter tools. Always drill the correct tap drill size for 3-56 UNF threads prior to tapping and ensure the workpiece is secured before beginning. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Back the tap off periodically to break chips, especially in blind-hole applications.
