OSG General Purpose Spiral-Point Taps.

Frequently Asked Questions

What is the OSG spiral point tap #12-28 UNF used for?

This OSG spiral point tap is used for threading blind or through holes in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing clogging. Common applications include automotive, aerospace, and general manufacturing where precise #12-28 UNF threads are required.

What are the specifications of the OSG spiral point tap 2809200?

The OSG spiral point tap model 2809200 has a #12-28 UNF thread size, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general-purpose tap designed for consistent thread quality. These specs ensure compatibility with standard UNF threaded holes in industrial workpieces.

Where to buy OSG spiral point tap 2809200 worldwide?

You can source the OSG spiral point tap 2809200 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; we supply this OSG tap to procurement teams internationally.

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

Select the OSG spiral point tap based on thread size, tolerance, and material. For #12-28 UNF threads, the H3 / 2B-3B tolerance suits general-purpose threading. Use a plug chamfer for through holes. Ensure your tap matches the hole depth and material hardness; consult OSG's technical data for optimal performance.
