Value Collection MSC-04473146 Straight Flute Tap 7/16-14

Product Description

The VALUE COLLECTION MSC-04473146 is a straight flute plug tap designed for cutting right-hand internal threads in through holes and shallow blind holes. Manufactured from high-speed steel with a bright uncoated finish, this tap produces 7/16-14 UNC threads and features four flutes for efficient chip clearance during the threading operation. The H3 thread limit provides a slightly oversize tolerance class suitable for use with standard coatings or platings applied after tapping. Machinists, maintenance technicians, and tool-and-die professionals install this tap in drill presses, CNC machines, lathes, or by hand with a tap wrench.

This tap is suited for general-purpose threading applications in ferrous and non-ferrous metals, plastics, and similar materials where 7/16-14 UNC threads are required. The plug chamfer — typically 3 to 5 threads — makes it the most versatile chamfer style for starting a thread in a drilled through hole or continuing after a taper tap. It is commonly used in production and maintenance environments for creating machine-screw and fastener threads in a wide range of workpiece materials.

Key Features

• 7/16-14 UNC thread form for standard fractional inch fastener applications
• Four straight flutes promote chip evacuation in through-hole and shallow blind-hole applications
• Plug chamfer style provides a good balance of cutting ease and thread lead-in versatility
• High-speed steel construction offers toughness and wear resistance across a broad range of materials
• Bright uncoated finish allows compatibility with post-process coatings or platings
• H3 thread limit class accommodates standard plating tolerances

Compatibility

Designed as a standard replacement or stock tap for any application requiring right-hand 7/16-14 UNC internal threads; accepts standard tap wrenches and holders sized for the shank diameter of this thread class.

Installation Notes

Secure the workpiece firmly before tapping and use the correct tap drill size for 7/16-14 UNC to achieve proper thread engagement. Apply a suitable cutting fluid or tapping compound to extend tool life and improve thread finish. Back the tap out periodically to break and clear chips, especially in deeper holes. De-energize and lock out any machine before installing or removing taps from powered spindles.
