Value Collection MSC-04439279 12-24 Unc Tap Set 3 Pc

Product Description

The VALUE COLLECTION MSC-04439279 is a 3-piece tap set designed for cutting 12-24 UNC internal threads in metal workpieces. Built from high-speed steel with a bright uncoated finish, this set includes the taper, plug, and bottoming taps needed to complete a full threading sequence by hand or machine. The 4-flute geometry provides clean chip evacuation and consistent thread form. Overall length is 2.375 inches with a thread length of 0.9375 inches. The H3 thread limit designates a standard tolerance class suited for general-purpose threading applications in production and maintenance environments.

This tap set is used in machine shops, maintenance facilities, and fabrication environments where 12-24 UNC threaded holes are required in steel, aluminum, brass, or similar materials. The right-hand thread direction covers the vast majority of standard fastener applications. The 3-piece set allows the technician to progress from taper to plug to bottoming tap, making it practical for both through-hole and blind-hole threading operations.

Key Features

• Thread size: 12-24 UNC, right-hand direction
• High-speed steel construction for durability across a range of workpiece materials
• 4-flute design promotes chip clearance and thread accuracy

Compatibility

Designed as a general-purpose replacement or addition for any 12-24 UNC tapping application requiring right-hand thread cutting in standard tap wrenches or tapping heads accepting this shank size.

Installation Notes

Secure the workpiece firmly before tapping and use the appropriate cutting fluid for the material being threaded. Start with the taper tap to establish thread alignment, then progress through plug and bottoming taps as needed. Apply steady, even pressure and back off periodically to break chips and prevent tap breakage. Follow applicable shop safety standards when operating tapping equipment.
