Value Collection JY4847323 Straight Flute Tap 3/4-32 Uns

Product Description

The VALUE COLLECTION JY4847323 is a straight flute tap designed to cut internal threads in a variety of materials encountered in trade and industrial settings. Built from high-speed steel with a bright/uncoated finish, this tap produces a 3/4-32 UNS right-hand thread to a 3B class of fit. The H3 thread limit provides consistent, controlled oversize tolerance for plated or tight-tolerance applications. With 4 flutes and a plug chamfer, it is suited for through-hole tapping where chips can evacuate forward. Overall length is 4.25 inches. Machinists, maintenance technicians, and tool-and-die professionals are the primary users of this tap.

This tap is used in applications requiring the Unified National Special (UNS) thread form at a 3/4-32 pitch, which falls outside standard UNC and UNF series. Typical install scenarios include threading hydraulic fittings, precision instrument housings, and specialty mechanical assemblies where a fine, non-standard thread pitch is specified. The plug chamfer style with 4 to 5 lead threads is appropriate for through-hole work and moderate-depth blind holes where lead-in alignment is manageable.

Key Features

• 3/4-32 UNS thread form for non-standard fine-pitch threading applications
• Plug chamfer with 4 to 5 lead threads for through-hole and moderate blind-hole tapping
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• 4 flutes promote chip evacuation during straight-flute tapping operations
• H3 thread limit supports applications requiring controlled tolerance for plated threads
• Bright/uncoated finish suitable for general-purpose use without coating-related dimensional concerns

Compatibility

Designed as an OEM-style replacement or standard tooling selection for any application requiring a 3/4-32 UNS internal thread with a 3B class of fit.

Installation Notes

This tap should be installed in a tapping head, CNC spindle, or hand tap wrench appropriate for the tap shank size. Ensure the workpiece is securely fixtured and properly center-punched or pilot-drilled to the correct tap drill diameter before tapping. Apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Never force a tap against resistance — back off periodically to break and clear chips, particularly in deeper holes.
