Value Collection MSC-04476115 Straight Flute Tap 5/8-11 Unc

Product Description

The VALUE COLLECTION MSC-04476115 is a straight flute plug tap designed for cutting 5/8-11 UNC right-hand internal threads in through holes and shallow blind holes. Built from high-speed steel with a bright uncoated finish, this tap handles general-purpose threading in ferrous and non-ferrous materials. The plug chamfer — typically 3 to 5 threads of relief — allows the tap to start easily and progress smoothly into the workpiece. With 4 flutes and an H3 thread limit, it produces a 3B class of fit suitable for standard fastener engagement. Machinists and maintenance trades use this style of tap in manual tapping operations as well as low-speed machine tapping setups.

This tap is suited for threading operations in manufacturing, maintenance and repair, and fabrication environments. The 5/8-11 UNC thread form is one of the most common coarse-thread sizes used in structural and mechanical assemblies. At 1-13/16 inches of thread length and 3-13/16 inches overall, this tool fits standard tap handles and floating tap holders used in drill press and CNC tapping applications at appropriate feeds and speeds for HSS tooling.

Key Features

• 5/8-11 UNC thread form for high-demand coarse-thread applications
• Plug chamfer for versatile use in through holes and moderately deep blind holes
• 4-flute design provides a balance of chip clearance and thread form support
• H3 thread limit holds 3B class of fit tolerances for standard fastener compatibility
• High-speed steel construction withstands the heat and stress of production tapping
• Bright uncoated finish works across a wide range of workpiece materials without coating compatibility concerns

Compatibility

Designed as a standard replacement or service tap for any operation requiring 5/8-11 UNC right-hand internal threads with a 3B class of fit. Compatible with standard tap handles, T-handle wrenches, and machine holders sized for the shank of a 5/8-inch tap series tool.

Installation Notes

Threading operations with this tap should be performed by a machinist or qualified maintenance technician familiar with speeds, feeds, and cutting fluid selection for HSS taps. Always secure the workpiece and align the tap square to the hole before starting to avoid tap breakage or thread misalignment. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Back the tap out periodically during hand tapping to break chips and clear the flutes.
