Frequently Asked Questions

What is the OSG spiral point tap #8-32 UNC used for?

The OSG spiral point tap #8-32 UNC is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral-point geometry pushes chips forward, reducing chip clogging and enabling faster tapping cycles in production environments.

What are the specifications of the OSG spiral point tap #8-32 UNC?

This OSG tap has a #8-32 UNC thread size, H4 / 2B-3B tolerance, 3 flutes, and a plug chamfer. The manufacturer part number is 2812908. It is a general-purpose spiral-point tap suitable for through-hole applications.

Where to buy the OSG spiral point tap #8-32 UNC worldwide?

You can source the OSG spiral point tap #8-32 UNC worldwide through 3G Electric. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct OSG spiral point tap for through-hole threading?

Select an OSG spiral point tap based on thread size, tolerance class, and material. For through holes, spiral point taps push chips ahead. Match the H limit to your desired thread class (e.g., H4 for 2B-3B). Always verify the tap's flute count and chamfer type for your application.
