Product Description

The VALUE COLLECTION MSC-04439246 is a 12-24 UNC straight flute hand tap designed for cutting right-hand internal threads in a range of materials. Built from high speed steel with a bright uncoated finish, this tap delivers consistent thread formation in standard shop and field applications. It features a plug chamfer, which provides a gradual lead-in suited for through-holes and blind holes with adequate clearance. The 4-flute straight flute design aids chip evacuation and helps maintain thread accuracy throughout the cut. Overall length is 2.375 inches with a thread length of 0.9375 inches.

This tap is intended for use in general metalworking, maintenance, and repair applications where 12-24 UNC threads are required. It is well suited for residential and light commercial trade work, including electrical, HVAC, and mechanical assembly tasks where small machine screws are standard. The plug chamfer makes it a practical choice for most standard tapping operations without the need for spiral flute or spiral point tooling.
