Value Collection MSC-04471264 Straight Flute Tap 5/16-24 Unf

Product Description

The VALUE COLLECTION MSC-04471264 is a straight flute tap designed to cut internal 5/16-24 UNF right-hand threads in ferrous and non-ferrous materials. Built from high-speed steel with a bright uncoated finish, this 4-flute taper tap provides a gradual thread engagement that reduces cutting force and helps align the tap on entry. It carries a 3B class of fit and an H3 thread limit, making it suitable for standard tolerance threaded holes in production and maintenance applications. Machinists, tool and die makers, and maintenance technicians are the primary users of this tool.

This tap is suited for hand tapping and machine tapping operations where a standard 5/16-24 UNF internal thread is required. The taper chamfer makes it well-suited for through-hole applications or as the first tap in a sequence when threading blind holes. It performs reliably in mild steel, aluminum, brass, and similar materials commonly encountered in general manufacturing, maintenance, and repair environments.

Key Features

• 5/16-24 UNF thread form for fine-pitch internal threading
• Taper chamfer provides gradual thread engagement and easy starting
• 4 flutes for balanced chip clearance and cutting stability
• High-speed steel construction handles a broad range of workpiece materials
• H3 thread limit and 3B class of fit for standard tolerance applications
• Right-hand thread direction compatible with standard tapping equipment

Compatibility

Designed as a standard replacement or production tap for any application requiring a 5/16-24 UNF internal thread. Compatible with standard tap handles, tapping heads, and CNC tapping attachments that accept this tap shank size.

Installation Notes

Secure the workpiece and ensure the tap is properly aligned before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. When hand tapping, advance the tap with steady forward pressure and periodically reverse to break chips. Inspect the tap for wear or chipping before each use and replace if damaged to avoid thread damage or tap breakage in the workpiece.
