Value Collection MSC-04473161 Straight Flute Tap 7/16-14

Product Description

The VALUE COLLECTION MSC-04473161 is a straight flute tap designed for cutting internal threads in through-holes and open-ended applications. Built from high-speed steel with a bright, uncoated finish, this taper-chamfer tap features 4 flutes and is ground to an H3 thread limit for consistent tolerance control. It cuts a 7/16-14 UNC right-hand thread, making it a standard choice for general-purpose threading operations in ferrous and non-ferrous metals. The taper chamfer distributes the cutting load across the lead threads, reducing stress and easing entry into the workpiece. Licensed machinists, toolmakers, and maintenance technicians install this tap in manual tap handles or machine tool spindles.

This tap is suited for production and maintenance threading in job shops, fabrication facilities, and industrial maintenance environments. The 7/16-14 UNC thread specification is widely used in structural fastening applications, making this tap appropriate for threading bolt holes in steel plate, machinery frames, fixtures, and general hardware assemblies. Its straight flute geometry is best applied in through-hole or blind-hole threading where chip evacuation is managed manually or with coolant flushing from above.

Key Features

• 7/16-14 UNC thread form for standard unified coarse fastener applications
• Taper chamfer entry distributes cutting load and aids thread lead-in
• 4 straight flutes provide rigidity and consistent chip clearance
• H3 thread limit ensures controlled tolerance fit for standard bolt clearances
• High-speed steel construction handles a broad range of workpiece materials
• Bright uncoated finish suitable for use with cutting fluid in general threading operations

Compatibility

Designed as a standard replacement or stocking tap for 7/16-14 UNC threading operations using compatible tap handles, T-handle wrenches, or machine tap holders sized for this shank diameter.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench or machine holder sized to the shank. Always secure the workpiece fully before tapping and ensure the tap is started square to the drilled hole to prevent breakage or cross-threading. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Never force a tap that has stalled in a blind hole — back off to clear chips before continuing.
