Value Collection MSC-04466124 Straight Flute Tap 5/8-11

Product Description

The VALUE COLLECTION MSC-04466124 is a straight flute bottoming tap designed to cut internal threads in pre-drilled holes where threads must extend as close to the bottom of a blind hole as possible. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread formation in a wide range of ferrous and non-ferrous materials. It cuts a 5/8-11 UNC right-hand thread and carries a thread limit of H2, indicating a Class 3 ground thread tolerance suitable for standard precision fits. With 4 flutes and a 1-13/16 inch thread length, it provides ample chip clearance for controlled cutting in shop and field applications.

This tap is suited for machine shops, maintenance facilities, and fabrication environments requiring bottoming-style thread formation in through-holes or blind holes where maximum thread depth is critical. The 5/8-11 UNC designation makes it a common choice for general-purpose fastener applications across structural, mechanical, and industrial assemblies. It is typically driven by a tapping head, CNC machine, or manual tap wrench depending on the application. The 3-13/16 inch overall length provides sufficient shank engagement for standard toolholding setups.

Key Features

• Bottoming chamfer allows threading to within 1-2 threads of a blind hole bottom
• High-speed steel construction handles a broad range of workpiece materials
• Bright, uncoated finish works well with standard cutting fluids
• H2 thread limit provides Class 3 tolerance for standard precision fits
• 4 straight flutes promote chip clearance and stable cutting geometry
• Right-hand thread direction compatible with standard tooling and fastener systems

Compatibility

Designed as a standard replacement or production tap for applications requiring a 5/8-11 UNC bottoming tap in high-speed steel with an H2 thread limit.

Installation Notes

A licensed machinist or qualified tradesperson should select the correct tap drill size for 5/8-11 UNC threads prior to tapping. Secure the workpiece fully before beginning the tapping operation, and use an appropriate cutting fluid to extend tool life and improve thread quality. When tapping blind holes, clear chips periodically to prevent tap breakage. Follow shop safety procedures and applicable standards for threading operations.
