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 pushes chips forward, preventing clogging and enabling faster tapping. Common applications include automotive, aerospace, and general manufacturing where clean, accurate threads are required.

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

This OSG tap has a #8-32 UNC thread size, H5 tolerance for the tap and 2B class for the nut. It features 3 flutes and a plug chamfer. The manufacturer part number is 2817800. It is a general purpose spiral-point tap designed for through-hole threading in various materials.

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

You can source the OSG spiral point tap #8-32 UNC (MPN 2817800) through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other OSG tapping tools.

How to select the correct OSG spiral point tap for my application?

Select the OSG spiral point tap based on thread size, pitch, and material. For through holes, spiral point taps are ideal as they push chips forward. Ensure the tap tolerance (e.g., H5) matches the required thread class (e.g., 2B). Consult OSG's technical data for material-specific speeds and feeds to optimize tool life.
