Value Collection MSC-04948345 Straight Flute Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04948345 is a straight flute tap designed for cutting 10-32 UNF internal threads in a left-hand direction. Built from high-speed steel with a bright uncoated finish, it features a taper chamfer for gradual thread engagement and a 2B class of fit for standard tolerance threading applications. With an H3 thread limit, it accommodates a controlled oversize condition suitable for plated or coated fastener applications. This tap is used by machinists, maintenance technicians, and tool-and-die professionals working on precision threaded assemblies where left-hand thread orientation is required.

This tap is suited for use on manual tapping operations or low-speed machine tapping in ferrous and non-ferrous materials. The 4-flute straight flute design provides rigidity and chip control in through-hole applications. With a 0.875 inch thread length and 2.375 inch overall length, it fits standard tap holders and handles common production and repair threading tasks in machine shops, industrial maintenance environments, and fabrication operations.

Key Features

• 10-32 UNF thread form for fine-pitch unified national thread applications
• Left-hand thread direction for applications requiring reverse-thread fasteners
• Taper chamfer (7-10 threads) for gradual thread engagement and reduced starting torque
• H3 thread limit for controlled oversize tolerancing
• 4 straight flutes for rigidity and chip evacuation in through-hole tapping
• High-speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish — no coating build-up affecting thread tolerances

Compatibility

Designed as an OEM-style replacement or production tap for applications requiring a 10-32 UNF left-hand straight flute tap with a 2B class of fit and H3 thread limit.

Installation Notes

This tap should be installed by a qualified machinist using an appropriate tap wrench or machine tap holder rated for the shank size. Always ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the surface before starting the thread. Use a compatible cutting fluid for the workpiece material to extend tap life and improve thread quality. Because this tap cuts left-hand threads, confirm thread direction requirements before use to avoid scrapping the workpiece.
