Value Collection MSC-04428256 Straight Flute Tap 10-24 Unc

Product Description

The VALUE COLLECTION MSC-04428256 is a straight flute bottoming tap designed for cutting 10-24 UNC internal threads in through-holes and blind holes where full thread depth close to the bottom is required. Manufactured from high-speed steel with a bright, uncoated finish, this tap offers adequate hardness and wear resistance for threading mild steel, aluminum, and similar workpiece materials. It features 4 flutes and an H2 thread limit, providing controlled tolerance for standard fit applications. Overall length is 2.375 inches with a thread length of 0.875 inches. The bottoming chamfer allows threading to within 1-2 thread pitches of the hole bottom.

This tap is suited for use in machine shops, maintenance and repair operations, and light manufacturing environments. The 10-24 UNC thread size is common in fastener applications across HVAC equipment panels, electrical enclosures, and general mechanical assemblies. Right-hand thread direction matches standard fastener convention. The straight flute geometry is appropriate for through-holes and short-chipping materials. It can be used in tapping machines, drill presses with tapping attachments, or hand tap wrench applications.

Key Features

• Bottoming chamfer allows threading to near full depth in blind holes
• 4 straight flutes for chip clearance in short-chipping materials
• H2 thread limit for standard tolerance internal thread fits
• High-speed steel construction provides hardness suitable for ferrous and non-ferrous workpieces
• Bright, uncoated finish — no coating build-up affecting thread tolerance
• Right-hand thread direction for use with standard fasteners

Compatibility

Designed as an OEM-style replacement or standard tooling option for any application requiring 10-24 UNC right-hand internal threads, compatible with standard tapping chucks, tap holders, and hand tap wrenches sized for this shank diameter.

Installation Notes

Use appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Ensure the hole is drilled to the correct tap drill size for 10-24 UNC threads before tapping. Power down any machine fully before changing or setting tooling. When tapping blind holes with a bottoming tap, use a taper or plug tap first to establish the thread before finishing with this bottoming tap.
