Value Collection JY4845236 Straight Flute Tap 9/16-24 Unef

Product Description

The VALUE COLLECTION JY4845236 is a straight flute plug tap designed for cutting right-hand internal threads in a 9/16-24 UNEF thread form. Manufactured from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in standard tapping applications. The plug chamfer — typically 3 to 5 threads of lead — makes it suited for through-hole and most blind-hole work where a starting chamfer is acceptable. With 4 flutes and an H3 thread limit, it holds close tolerances appropriate for general-purpose threading in a shop or field environment. Overall length is 3-19/32 inches and the tap weighs 0.33 pounds.

This tap is intended for use in metalworking operations where a 9/16-24 UNEF internal thread is required. The UNEF thread form is a fine-pitch unified national extra-fine standard commonly found in thin-walled tubing, bearing retainer nuts, and precision assemblies. It is appropriate for use in manual tap handles, tapping heads, and CNC rigid-tapping setups. Machinists, tool and die makers, and maintenance technicians across manufacturing, automotive, and aerospace maintenance environments are the typical end users. The straight flute geometry is best suited for short-chipping materials such as steel, cast iron, and brass.

Key Features

• 9/16-24 UNEF thread form for fine-pitch threading in thin-walled and precision components
• High-speed steel construction provides durability across a range of ferrous and non-ferrous materials
• Plug chamfer with 4 flutes balances cutting efficiency and chip clearance in through-hole and blind-hole applications
• H3 thread limit ensures consistent fit within standard tolerance classes for UNEF threads
• Bright, uncoated finish suitable for use with cutting oils and standard tapping fluids
• Right-hand thread direction, compatible with conventional tapping tooling and setups

Compatibility

Designed as a straight flute plug tap for cutting 9/16-24 UNEF right-hand internal threads. Compatible with standard tap wrenches, T-handle tap holders, and machine tapping chucks sized for the appropriate tap shank.

Installation Notes

This tap is installed by machinists and tool and die professionals using standard hand or machine tapping equipment. Always ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 9/16-24 UNEF thread prior to tapping. Apply a suitable cutting fluid to reduce friction and extend tap life, especially in steel. Reverse the tap periodically during hand tapping to break chips and prevent binding.
