Value Collection JY4847232 Hand Tap 3/4-27 Uns Plug Hss

Product Description

The VALUE COLLECTION JY4847232 is a 3/4-27 UNS straight-flute hand tap designed for cutting internal threads in metalworking and machining applications. Built from high speed steel with a bright, uncoated finish, this tap delivers reliable performance in a wide range of threading tasks. The plug chamfer style — typically 3 to 5 threads of lead — makes it suitable for through-holes and moderately deep blind holes. With 4 flutes and a right-hand thread direction, it is rated to a Class 3B fit at thread limit H3, ensuring threads meet standard tolerance requirements for close-fit assemblies. The overall length is 4.25 inches.

This tap is used in general machining, maintenance, and repair operations where a 3/4-27 UNS internal thread is required. It is appropriate for manual tapping with a tap wrench in both shop and field environments. Machinists, millwrights, and maintenance professionals working with ferrous and non-ferrous metals commonly reach for this tool when cutting non-standard unified special threads. The bright finish makes it a cost-effective choice for low-volume or intermittent threading work where a coated tap is not necessary.

Key Features

• 3/4-27 UNS thread specification for non-standard unified special thread applications
• Plug chamfer provides a self-starting lead suitable for through-holes and open blind holes
• High speed steel construction offers good wear resistance across common metals
• 4-flute straight-flute design for chip control in through-hole tapping
• Class 3B fit at H3 thread limit for consistent close-tolerance internal threads
• Right-hand thread direction, standard for most manual tapping operations

Compatibility

Designed as a standard hand tap for use with a tap wrench or tapping fixture where a 3/4-27 UNS internal thread is required.

Installation Notes

This tap is intended for use by trained machinists or maintenance professionals using a tap wrench or equivalent manual tapping tool. Always secure the workpiece firmly before tapping and apply appropriate cutting fluid to extend tool life and improve thread quality. Back off the tap periodically to break chips and prevent binding, particularly in deeper holes. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
