Value Collection JY4846101 Straight Flute Tap 5/8-16 Uns

Product Description

The VALUE COLLECTION JY4846101 is a straight flute tap designed for cutting 5/8-16 UNS internal threads in machined parts and assemblies. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in a range of ferrous and non-ferrous workpiece materials. The plug chamfer — typically 3 to 5 threads — makes it well suited for through-hole tapping where partial engagement is acceptable before full thread formation begins. With 4 flutes and an H3 thread limit, this tap maintains consistent tolerance control to a 3B class of fit, making it appropriate for standard-tolerance threaded fastener applications in production and maintenance environments.

This tap is used in machining, fabrication, and MRO settings where UNS thread forms are required. The 5/8-16 UNS specification is common in specialized mechanical assemblies where neither standard UNC nor UNF pitch series applies. At 3-13/16 inches overall length, the tap accommodates typical drill chuck and tap holder setups on manual mills, drill presses, and CNC machining centers. Machinists, tool-and-die makers, and maintenance technicians handling custom or legacy thread specifications will find this a direct-fit solution for that application.

Key Features

• 5/8-16 UNS thread form for non-standard pitch applications
• High-speed steel construction for durability across a range of workpiece materials
• Plug chamfer (3 to 5 thread lead) suited for through-hole tapping operations
• 4 straight flutes for chip clearance in standard tapping conditions
• H3 thread limit holds 3B class of fit tolerances
• Right-hand thread direction; no coolant-through requirement

Compatibility

Designed as an OEM-style cutting tool replacement for applications requiring a 5/8-16 UNS straight flute plug tap in standard tap holders, collet chucks, or drill press tap fixtures.

Installation Notes

This tap is installed by qualified machinists or tool-and-die professionals using a standard tap wrench, tapping head, or rigid CNC tap holder sized for the shank diameter. Always ensure the pilot hole is drilled to the correct tap drill size for a 5/8-16 UNS thread before beginning the tapping operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect flutes and chamfer for wear or chipping before each use; a damaged tap can ruin the workpiece thread and create a broken-tool extraction situation.
