Frequently Asked Questions

What is OSG spiral point tap 5/16-24 UNF used for?

This OSG spiral point tap is used for threading blind or through holes in steel, stainless steel, and non-ferrous materials. Its bottoming chamfer and 2-flute design push chips forward, making it ideal for production tapping where chip evacuation is critical.

What are the specifications of OSG tap 1231300?

The OSG tap 1231300 is a 5/16-24 UNF spiral point tap with H3 / 2B-3B tolerance, bottoming chamfer, 2 flutes, and high-speed steel construction. It is designed for general-purpose threading in a wide range of materials.

Where to buy OSG 1231300 tap worldwide?

How to select the right OSG tap for UNF threads?

Select an OSG tap based on thread size (5/16-24 UNF), chamfer type (bottoming for blind holes), flute count (2 for chip control), and tolerance class (H3 for 2B-3B fit). High-speed steel suits general-purpose use; consult OSG's catalog for material-specific coatings.
