Value Collection JY4847208 Straight Flute Tap 3/4-24 Uns

Product Description

The VALUE COLLECTION JY4847208 is a straight flute tap designed for cutting 3/4-24 UNS internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading applications. The plug chamfer style provides a balanced entry, making it suitable for through-hole and moderately deep blind-hole threading. With 4 flutes and an H3 thread limit, it holds tight tolerances to a Class 3B fit. Overall length is 4.25 inches. Right-hand thread direction is standard. Machinists, toolmakers, and maintenance trades use this tap in manual tap handles, tapping fixtures, and machine setups.

This tap is suited for production and maintenance threading tasks where a UNS 3/4-24 thread form is required. The 3/4-24 UNS designation is common in precision mechanical assemblies, instrumentation fittings, and specialty fastener applications where standard UN or UNC thread counts do not apply. The 4-flute straight flute geometry performs well in shorter-chipping materials such as steel, cast iron, and brass. The plug chamfer allows the tap to start easily in pre-drilled through holes and is the most common general-purpose chamfer style for shop use.

Key Features

• 3/4-24 UNS thread size with right-hand thread direction
• 4 straight flutes for stable cutting in short-chipping materials
• Plug chamfer for easy entry in through-hole and open blind-hole applications
• Class 3B fit with H3 thread limit for close-tolerance threading
• High-speed steel construction for durability across common shop materials
• Bright, uncoated finish — no additional surface treatment

Compatibility

Designed as a general-purpose straight flute tap for use in standard tap handles, T-handle wrenches, tapping arms, and CNC or manual tapping attachments that accept the corresponding shank size.

Installation Notes

This tap is installed by machinists and toolroom trades using manual or machine tapping equipment. Always pre-drill the correct tap drill size for a 3/4-24 UNS thread before use, and secure the workpiece firmly before starting. Apply appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. Reverse the tap periodically when hand-tapping to break chips and prevent binding.
