Value Collection JY4838447 Straight Flute Tap 10-48 Uns

Product Description

The VALUE COLLECTION JY4838447 is a straight flute tap designed for cutting internal threads in a variety of materials. Built from high-speed steel with a bright/uncoated finish, this tap produces a 10-48 UNS right-hand thread with a plug chamfer and 3B class of fit. The H2 thread limit provides a controlled oversize allowance suited to standard tolerance threading applications. At 2.375 inches overall length, it fits standard tap handles and machines used in general metalworking and maintenance operations. Machinists, tool and die workers, and maintenance technicians rely on this type of tap for thread repair and new thread creation in ferrous and non-ferrous workpieces.

This tap is suited for threading operations where a 10-48 UNS thread form is required. The plug chamfer — typically 3 to 5 threads of taper — makes it appropriate for through-hole applications and for starting threads in blind holes when paired with a bottoming tap for final depth. The 4-flute straight design works well in shorter-chipping materials. It is commonly used in general machining shops, assembly operations, and field maintenance where fine-pitch UNS threading is needed in small fastener applications.

Key Features

• 10-48 UNS thread form with right-hand thread direction
• Plug chamfer for through-hole and general-purpose threading
• High-speed steel construction for durability across a range of workpiece materials
• 3B class of fit for standard tolerance internal threads
• H2 thread limit for controlled oversize allowance
• 4 straight flutes suited to shorter-chipping materials
• Bright/uncoated finish — no coating buildup affecting thread tolerance

Compatibility

Designed as a standard straight flute tap for use with conventional tap handles, tapping heads, and CNC tapping attachments that accept tooling of this shank size and overall length.

Installation Notes

Tapping operations should be performed by a qualified machinist following standard threading procedures. Secure the workpiece fully before beginning and use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Do not force the tap if resistance increases — back off to clear chips before continuing. Inspect the thread with a go/no-go gauge after tapping to verify 3B class of fit compliance.
