Value Collection MSC-04466116 Straight Flute Tap 5/8-11 Unc

Product Description

The VALUE COLLECTION MSC-04466116 is a straight flute tap designed for cutting right-hand internal threads in through-holes and moderately interrupted cuts. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap is suited for general-purpose threading in a wide range of ferrous and non-ferrous materials. It features a 5/8-11 UNC thread form, 4 flutes for efficient chip clearance, and a plug chamfer that distributes cutting load across the leading threads. Thread length is 1-13/16 inches and overall length is 3-13/16 inches. Machinists, toolroom technicians, and maintenance trades use this tap in production and repair threading applications.

This tap is intended for use in through-hole threading operations where straight-flute geometry is appropriate for the material and chip evacuation requirements. The plug chamfer style makes it suitable for starting threads partway down a hole or threading completely through stock. It is commonly used in manual tapping, drill press, and light CNC applications across machine shops, maintenance facilities, and fabrication environments where 5/8-11 UNC fastener threads are required.

Key Features

• 5/8-11 UNC thread form for standard unified coarse-pitch internal threads
• 4-flute straight design promotes chip clearance in through-hole applications
• Plug chamfer distributes cutting load across several leading threads for smoother thread entry
• High-speed steel construction provides durability across a range of common workpiece materials
• Bright, uncoated finish — no coating buildup, suitable for use with cutting fluid
• H2 thread limit for controlled tolerance fits in standard UNC applications
• Right-hand thread direction for standard fastener compatibility

Compatibility

Designed for cutting 5/8-11 UNC right-hand internal threads in through-hole applications. Compatible with standard tap holders, T-handle tap wrenches, and machine tool spindles sized for this shank diameter.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using appropriate tap holders or wrenches. Always secure the workpiece before tapping and align the tap perpendicular to the work surface to avoid thread misalignment or tap breakage. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread quality. Never reverse a tap under power without confirming the holder and machine support reverse rotation.
