Value Collection MSC-04473229 Straight Flute Tap 7/16-20 Unf

Product Description

The VALUE COLLECTION MSC-04473229 is a straight flute tap designed for cutting internal 7/16-20 UNF right-hand threads in metal workpieces. Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread geometry across production and maintenance applications. The taper chamfer eases entry into the workpiece, reducing the torque required to start the cut. With 4 flutes and an H3 thread limit, it maintains dimensional accuracy in through-hole and open-ended tapping operations. Overall length is 3-5/32 inches with a thread length of 1-7/16 inches, making it suited for standard depth threading tasks handled by machinists, maintenance techs, and tool-and-die professionals.

This tap is used wherever 7/16-20 UNF internal threads are required, including fastener repair, component fabrication, and general machine shop work. The taper chamfer style is the standard choice for starting threads in through holes and for general-purpose hand or machine tapping. It is appropriate for use in ferrous and non-ferrous metals where high-speed steel tooling provides adequate tool life. No coolant-through capability is present, so external cutting fluid application is standard practice during use.

Key Features

• 7/16-20 UNF thread form for fine-pitch internal threading
• Taper chamfer for easy thread start and reduced entry torque
• 4 straight flutes for efficient chip clearance in through-hole applications
• H3 thread limit for consistent dimensional tolerance control
• High-speed steel construction provides durability across common metal types
• Bright, uncoated finish suited for use with standard cutting fluids

Compatibility

Designed as a standard replacement or tooling addition for any application requiring 7/16-20 UNF internal threads. Compatible with standard tap handles, tapping heads, and machine tool holders sized for this shank diameter.

Installation Notes

This tap is installed and used by machinists, maintenance technicians, and tool-and-die professionals. Secure the workpiece firmly before tapping and ensure the drilled hole is sized correctly for a 7/16-20 UNF tap. Apply appropriate cutting fluid throughout the operation to reduce friction and extend tool life. For machine tapping, verify spindle speed and feed rate are set for the material being threaded before starting the cut.
