Value Collection MSC-04438263 Tap 10-24 Unc 4 Flute Hss

Product Description

The VALUE COLLECTION MSC-04438263 is a straight flute hand tap designed for cutting internal threads in through-holes and open-work materials. Built from high-speed steel with a bright, uncoated finish, this tap produces 10-24 UNC threads in a right-hand direction. The taper chamfer — typically 7 to 10 threads of lead — allows gradual thread engagement, making it well suited for starting threads accurately and reducing torque demand at the point of entry. Thread length measures 0.875 inches and overall length is 2.375 inches. The H3 thread limit keeps finished threads within a controlled tolerance range for consistent fit across production runs.

This tap is used in general machining, maintenance, and fabrication work where 10-24 UNC internal threads are required. The taper chamfer style is most common for through-hole applications and initial thread-starting in harder materials. It covers both 2B and 3B class of fit, giving machinists flexibility across standard commercial and closer-tolerance applications. Straight flutes perform reliably in cast iron, steel, aluminum, and other short-chipping materials where chip evacuation out the flute is not a concern.

Key Features

• 10-24 UNC right-hand thread profile for standard unified coarse fastener applications
• High-speed steel construction provides good wear resistance across a range of workpiece materials
• Taper chamfer with 4 flutes eases thread starting and distributes cutting load gradually
• H3 thread limit ensures dimensional control for 2B and 3B class of fit requirements
• Bright, uncoated finish — suitable for use with cutting fluid in most standard tapping operations
• Compact 2.375-inch overall length fits standard tap handles and machine setups

Compatibility

Designed as a standard replacement or working tap for any application requiring 10-24 UNC internal threads. Fits conventional tap handles and machine tap holders sized for this shank diameter.

Installation Notes

Machinists and maintenance technicians should use the correct tap drill size for 10-24 UNC threads before tapping to ensure proper thread engagement and avoid tap breakage. Apply appropriate cutting fluid throughout the tapping operation. Back off periodically to break chips, particularly in deeper holes, even though straight flutes are best suited for through-hole work. Secure the workpiece firmly and align the tap perpendicular to the work surface before applying torque.
