Osg 1069002 Straight Flute Tap 10-24 Unc Plug Hss

Product Description

The OSG 1069002 is a straight flute plug tap designed for producing internal threads in a wide range of metallic workpiece materials. Configured to a 10-24 UNC thread standard with a right-hand thread direction, it features 2 flutes and a plug chamfer, which provides a gradual lead-in that balances cutting forces across several starting threads. Constructed from high-speed steel, the tap delivers consistent thread quality across production and maintenance tapping applications. The overall length is 2.375 inches with a thread length of 0.875 inches. It carries a thread limit designation of H2, indicating a close tolerance fit suited to general-purpose threading work.

This tap is suited for hand tapping and machine tapping operations in jobshop, maintenance, and light manufacturing environments. The plug chamfer makes it a practical choice for through-hole applications where the tool can pass fully through the workpiece. It is cataloged under OSG Series 104 and is appropriate for use in drill presses, tapping heads, and CNC machining centers operating at feed rates matched to the 10-24 pitch.

Compatibility

Compatible with aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpiece materials. Designed as a standard OEM-style replacement or new-installation tap for any setup requiring 10-24 UNC internal threads.

Installation Notes

Installation should be performed by a machinist or qualified trades professional familiar with tapping operations and speeds appropriate to the workpiece material. Always ensure the tap is properly aligned with the drilled pilot hole before engagement to avoid tap breakage or cross-threading. Secure the workpiece firmly and use a tapping fluid or cutting oil appropriate to the material being threaded. Inspect the tap for wear or chipping before each use.
