Frequently Asked Questions

What is the OSG Spiral Point Tap #12-28 UNF used for?

The OSG Spiral Point Tap #12-28 UNF is used for threading holes in through-hole applications in metalworking. Its spiral-point design pushes chips ahead, reducing chip clogging. It is suitable for general-purpose tapping in materials like steel, aluminum, and cast iron, commonly used in automotive and industrial manufacturing.

What are the specifications of the OSG Spiral Point Tap MPN 1214501?

The OSG Spiral Point Tap MPN 1214501 has a #12-28 UNF thread size, H3 / 2B-3B tolerance class, 2 flutes, and a bottoming chamfer. It is a general-purpose spiral-point tap designed for through-hole threading. The H3 tolerance ensures precise fit for 2B-3B class threads in production environments.
