Value Collection MSC-04519245 Spiral Point Tap 12-24 Unc

Product Description

The VALUE COLLECTION MSC-04519245 is a spiral point tap designed for cutting 12-24 UNC internal threads in through-hole applications. It features 2 flutes and a plug chamfer, making it well suited for machine tapping operations where chips need to be pushed forward and clear of the cutting zone. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in a wide range of ferrous and non-ferrous materials. The H3 thread limit and 2B/3B class of fit ensure compatibility with standard fastener tolerances used across the trade.

This tap is used in machine shop, maintenance, repair, and fabrication environments where 12-24 UNC threaded holes are required in through-hole workpieces. Its plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for general-purpose tapping in production and job-shop settings. Right-hand thread direction is standard for conventional 12-24 UNC fastener installations. The 15/16 inch thread length provides adequate engagement depth for most typical fastener lengths used in light structural and mechanical assemblies.

Key Features

• 12-24 UNC thread form with H3 thread limit for consistent 2B/3B class of fit tolerances
• Plug chamfer (3-5 thread lead) optimized for through-hole tapping applications
• 2-flute spiral point design pushes chips forward ahead of the cutting zone
• High speed steel construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish suits general-purpose use without coating-specific material restrictions
• Right-hand thread direction matches standard 12-24 UNC fastener orientation

Compatibility

Designed as a standard replacement or stock tap for any machine or hand tapping setup requiring 12-24 UNC thread form with a 2B/3B class of fit and H3 thread limit.

Installation Notes

This tap is installed and operated by machinists, toolroom technicians, or maintenance professionals using a tapping head, CNC machine, drill press, or hand tap wrench. Always ensure the workpiece is secured and the spindle speed is appropriate for the material and tap diameter before beginning. Apply cutting fluid or tapping lubricant to reduce heat and extend tool life. Do not reverse the tap to break chips during spiral point tapping in through-hole operations, as the chip-pushing design handles chip evacuation in the forward direction.
