OSG Spiral Flute Tap: 3/8"-24 UNF, H3 / 2B-3B, 3 Flute, Plug Chamfer

The OSG spiral flute tap is used for threading blind holes in materials such as steel, stainless steel, and aluminum. Its spiral flute design pushes chips upward, preventing clogging and ensuring clean threads. It is ideal for automotive, aerospace, and general manufacturing applications requiring precise UNF threads.

The OSG 1431000 is a spiral flute tap with thread size 3/8-24 UNF, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and is designed for general-purpose threading. The H3 tolerance ensures precise fit for 2B-3B class threads.

Select an OSG tap based on thread size, pitch, material, and hole type. For blind holes, use a spiral flute tap like the 3/8-24 UNF model to evacuate chips. Match the tap tolerance (e.g., H3) to the required thread class (2B-3B). Consult OSG's technical guides for material-specific speeds and feeds.
